I'm planning to build an RC heli UAV, with a control and video uplink through 3G network, based on either stripped down Kaiser, or Eten Glofiish x800. I would need software that would allow Kaiser to receive commands via the internet and transform them into commands for the control surfaces of the Heli, probably via the USB port on the phone. Being able to tap into the raw data from the GPS chip on the phone would also be nice. Can someone with some tinkering experience advise me if this is feasible? Thanks.
try some BT to serial adapter and connect the controls to that serial port.
Should be way easier then using usb.
Great idea. My concern with that is adding another wireless link creates more latency and another potential point of failure. But lacking a viable USB solution, this is worth trying.

As I understand it you are going to try and use the Kaiser as a remote control for a remote control helicopter? Can I come and watch the crash?
The lag time in response is going to be so large you will not be able to control the heli - you need instantaneous response that you will get with RADIO control/RF - internet and no joystick will kill the copter.

No Bill,
I want to use Kaiser as the brains of the heli. Kaiser already has 2 built in cameras, GPS chip, status lights (for switching various components), 3G network (serving as a video and control conduit), a powerful CPU for basic video compression and autonomous logic, memory for hi-res photo storage, All of this is packed in the weight of a few dozen grams (once you strip case, screen, and keyboard), makes it a perfect platform to build a heli on.
The main issue as you correctly point out is latency. On ATT 3G network it's b/w 100 and 200 ms. This seems to be sufficient to control a remote craft, but I havent tested it, provided there is virtually no delay in other aspects of delivering commands to the controls.
Microsoft Robotics Studio is probably the best place to start...but I think that latency will become an issue. http://www.wimobot.com/

I can state catogorically - that no matter how much I love this phone and the current ROM - there are ALWAYS some "pauses" when you are using the internet - where "something" chokes and pukes.
When you are flying a remote control even a 1 second hiccup can be fatal to your craft.
I concur - I believe that latency will be the issue to overcome.

wouldn't there be a way to just add a program with no gui front in to run it. The video and everything lags it. I'm sure you could do something you have to remote into to adjust.. super simple.
I only picked Kaiser because it has 3G, 2 cameras, and GPS chip. If you can suggest an alternative HTC phone, I'd be glad to hear it (no x7500 please). Don't forget though, that the phone will not be used to render graphics on screen, which, as I think, is its main bottleneck due to missing graphics drivers. Also, it will only run programs necessary for aircraft operation, and none of the bloat that most people's phones are loaded with.
Thanks for the Wimobot link. It's very useful.
I heard the iphone 3g can get er done.

Nah, they use it to control the craft. It's surprising that it has even made news. I guess its all due to the iPhone hype. If they had made iPhone the brains of their UAVs, that would be a story then.
That would work well witht that phone, from what I understand it has something inside of it to tell it when it's level and upside down.
I think what he wants is real time operation of an aircraft. That iPhone story seems to say that the iPhone was used to send coordinates to the aircraft and they aircraft did the thinking.
Are you planning on having the phone inside of the heli or using the phone to talk to the heli? I've worked with many WM 6.0 phones and ALL of them seem to go slow. What is needed is a faster processor like the Diamond or Pro will have.
iPhone has a set of built in accelorometers. Unfortunately, I think they are not sensitive enough to use them to stabilize a heli, but I have to look into that.
Yes, they used iPhone to send directions to the UAVs, which can be done with any cell phone via text messaging or EDGE, or wireless, or Bluetooth, or voice-modem, frankly, making anything that has iPhone in it a news item is getting ridiculous.
Diamond and Pro are rather on the expensive side. From my experience with Wizard and Wing, the hardware specs are not bad, it seems the bottleneck is graphics and running many applications in parallel. In my case, it would only be video transmission through a service like Qik, AI for autopilot, and commands sent to that AI through 3G or as a fallback, SMS. While it sounds resource-intensive, people have made homebrew autopilots for their planes using 8Mhz cpus.
My main concern is how to get the AI autopilot soft running on the smartphone to interface with motor and servos. So the main issue is getting a low level USB driver that would allow in/out via USB, but in analog fashion.
I would suggest making your own computer for it.

Chumley,
Those things together weigh 3 times more than stripped Kaiser, and thats not counting increased power consumption.
I ended up getting a RC heli for xmas. A nice fancy one at that. Now I'm too scared to fly it and need to drop it on ebay.
Ok, I think this is a new subject:
I am getting ready to buy/lease a new car in the next couple of months. Would like everyone's opinion/advice.
1. Which cars have bluetooth built-in that work with Kaiser over the speakers for both music and for phone?
2. Which cars work with bluetooth for voice-dialing (i.e. have some sort of microphone built-in)?
3. Which cars have the best PLACEMENT options for the Kaiser for GPS navigation (i.e. best line of sight for where the Kaiser would sit to be viewable)?
ONLY REQUIREMENTS: Cars have to be less that $50,000 (ouch!) and options to enable #1, 2, or 3 CANNOT require physically changing anything in the car (it may be leased, instead of bought).
Your wisdom is GREATLY anticipated.
You are planning on making a $50,000 purchasing decision based on a piece of equipment worth about $500?
Not that you don't have some valid questions... but realize how ludicrous the concept is.
There are plenty of cars out there (well below $50K) that have integrated bluetooth and GPS (and other voice activated things like music) so that using your phone (which is a poor option in comparison to dedicated solutions) should not even be necessary.
Buy a car based on the cars functionality...not whether you can plug in an easily expendable device!

Hmm... just wanted to point out a few things to consider:
1. The life-cycle of your vehicle should extend well beyond your phone.
2. For a $50,000 vehicle, it will hopefully have a GPS navigation built-in.
In any case, if the BT compatibility is that high on your priority list... test it out when you test drive the vehicle. I don't think the dealership will mind, and if they do - pull off the side of the road during your test drive and configure. The Internet is a wealth of information for manuals and procedures to configure without the help of the dealership.
Good luck with your choice, and let us know your selection.
Thanks, guys....for the reality check
I am NOT basing my decision on this question...but it is a factor as to which cars are worth looking at that HAVE these features. I chose $50K as an arbitrary number because I can't even think of anything more expensive that will do these things.
My real question is which cars out there play well and integrate well with our device (or future devices)?
Many factors (for me) go into a purchase/lease decision:
-safety ratings
-fuel economy
-comfort
-cost
-style
and one of them has to do with bluetooth integration...
For example, I know that the Toyota Prius has bluetooth integration. How is it? Are there others that do? What are your experiences with it?
So...while I really and honestly appreciate the "get real" advice - which is sound - if someone(s) could comment on the specific questions, it would help as I begin my search.
I have a ford edge with nav and sync. Phone syncs quickly and works well. I can push music over the bluetooth through it, it downloads my phonebook so I can hands free voice dial. The only thing the phone doesn't support in sync is reading text messages over it. Some issues I have run into since I upgraded to 6.1 though is after I pair it, then get out, it likes to set my ringer to silent, but not all the time. I Don't use phone for nav, I have found the screen too small to see clearly when driving and it eats the battery. I hope this helps.
I use my Diamond as an MP3 player way more than a phone. I also use a Sony Ericsson Bluetooth Headset HBH-DS970 all the time. But very often I'll be listening when boom! The sound stops for some unknown reason. Many times it's a brief second or two and it starts again. Other times I reach into my pocket and hit the power button and poof, it starts again. Annoyed I put it back in my pocket.
Then sometimes it doesn't come back to life. Of course, I'm driving at the time and have to fiddle with the phone and drive, which is very dangerous.
Very often the bluetooth just drops. I have to go in, hit the power button, slide to unlock, Start: Settings: Connections: Bluetooth: Mode and I see the Turn on Bluetooth and Make this device visible to other devices toggled off even though I can see the little Bluetooth icon in the title bar is still on! I toggle on these and hit OK. Often I need to power off and back on my HBH-DS970 to re-establish the Bluetooth connection. Now the HTC Touch Diamond does not play a sound when the bluetooth establishes itself like my old PPC-6700 so I just guess and hit play on the HBH-DS970. Sometimes the I have the Wireless stereo portion working but the AVRCP is not working so play on the HBH-DS970 doesn't work and I have to hit play on the HTC Touch Diamond (Sprint Music). Later I'll find that Wireless stereo is working but Hands Free is disabled.
So why does this happen? Why does the Bluetooth drop at all? Is there any better Bluetooth stacks that have less bugs that I can install. I recall tell about something like a Widecom Bluetooth stack or whatever. Is that any better?
Recently I purchased a Motorola Rokr unit which is a unit for your car that receives a Bluetooth signal and rebroadcasts it to FM for your car stereo. It works great but the having to transfer Bluetooth pairing from my headset to the Rokr when I get in the car never goes smoothly. I have to remember to pause the program, stop the Bluetooth going to the headset, turn on the Rokr, it attempts to connect to the phone and it cannot if the phone is talking to the headset via Bluetooth. Why's that an issue? Why can't the Bluetooth talk to more than one device at the same time?!? I mean what if I want the Bluetooth music or program to go to two headsets simultaneously or to the headset and the Rokr? Shouldn't that be my choice.
Next I need to tell the Rokr to transmit on FM and establish that connection. Then I try to hit the pause/play button on the Rokr and often again, the Wireless is paired up to the Rokr but the Hands Free isn't. Get out the phone, power button, slide to unlock, Start: Settings: etc. etc. - what a pain.
Then I'll be driving and listening and life is good when suddenly again, the connection drops. The Rokr cutely has a female voice that comes on through the radio saying "Connection dropped". Yeah I know - and I'm not impressed!
Repeat procedure in reverse when leaving the car transferring the Bluetooth signal from the Rokr -> HBH-DS970.
LIFE SHOULD NOT BE THIS DIFFICULT!!!
So I ask:
. Is there a better, more reliable Bluetooth stack I can install?
. If not, are there some registry settings that I can tweak to make Bluetooth more reliable? I have used the Advanced Configuration tool and saw some settings about Bluetooth sound quality but I don't know if upping th quality had lessoned the reliability...
. What are some of the reasons that a Bluetooth connection will drop? I mean it's not like I've walked outside of its broadcast range - hell I'm still in the car!
. Finally, is there anything I can do to lesson the amount of short micro drops of 1/2 - 1 second? It's a little annoying when you're grooving to a tune and that happens.
Thanks.

OT, can you record sound via BT headset's microphone? Not being able to do that annoys me much and still haven't got any answers from anybody.
I use the Bluetooth with phone calls. With Vito's Audio Notes I can record phone calls and hear both me and the caller in the recording - through the Bluetooth. I see Vito also has a "finger friendly" recorder but I'm not interested in that. However it seems clear the audio path from Bluetooth mic to recording can work.
Thanks for the pointer to that thread however the concern there is about Bluetooth quality not Bluetooth reliabiliy. Personally my Bluetooth quality is just fine - when the Bluetooth remains connected that is! I'm puzzled why you would have read my post and thought I wanted better Bluetooth quality?
I have been streaming audio since i got my HTC Wizard - 2 phones ago..
Back then, i was running WM5 and it had notoriously bad BT stack (really bad quality of A2DP audio). No tweak could eliminate the horrible high-pitched noise.
Fed up with the terrible sound, i tried the Widcomm stack.
This dramatically improved audio quality, but the Widcomm stack had other problems; i was not able to use any of my other BT devices. (back then i had a seperate GPS device and a Jabra wireless earpiece).
Eventually i managed to have both BT stacks installed, so i could choose which stack to start, depending on what i was going to use.
However, this was still far from perfect, because i wanted to be able to use my earpiece, use Tom Tom and listen to music at the same time (in my car).
The solution came (for me) with WM6, it had a really improved BT stack, the A2DP audio sounded much better.
For other applications the Microsoft stack worked well from the beginning.
When i just started using WM6 it did need some (registry) tweaking to overcome the problem of the "skipping" that sometimes occurred (those skips were not due to disconnection problems, it was just a matter of figuring out the highest bitrate the device could handle! (=>higher bitrate = better sound, more bandwidth, higher chance of music "skipping", =>lower bitrate = more stabile connection (less "skips", at the price of lowering the audio quality)).
Since my last phone (HTC touch) i did not even need to apply that tweak anymore, standard settings worked fine for me (acceptible audio quality, no 'skipping' problem).
Today i have a HTC Diamond, and i use a MBR-100 to stream audio to, i hook this device up to my car stereo (in fact, i have two, so i never run out of battery power).
I use my Jabra earpiece simultaneously.
I have no complaints whatsoever.
So to answer some of your questions, based on my own findings :
- The WM6 BT stack is capable of handling multiple connections at the same time (in my case, A2DP, remote GPS and Jabra earpiece)
- I never had a disconnect from my MBR-100 (which is also from sony Ericsson) without reason.
- I recently discovered,i can activate A2DP just by pressing the button on the MBR-100. Before, i always activated the connection by going to => settings=> Bluetooth etc. Maybe you have a button that does that on your headset? If so, it will at least save you the trouble setting up the connection again on your Diamond...
Finally, i don't know which ROM you are using, but the one i'm running now is the one from the official HTC website, "_HTC Touch Diamond_QMR_RUU_Diamond_HTC_NLD_1.93.404.1_Radio_Signed_Diamond_52.29.25.12_1.00.25.05_Ship.exe".
One more thing :
- It is not possible to stream A2DP to more than one device at the time.
However, i found a nice little program to switch the A2DP stream between paired BT devices in reach.
It can also toggle the sound (and mic) from a phone call between my earpiece and the internal speaker.
Maybe it is useful for you as well : LINK
Copy .exe to the phone and execute there (when you have a A2DP connection running).

After toggling the sound by means of the program i mentioned in my previous post (This one) it definately records sound trough the earpiece (it's a Jabra BT350).
Thoroughly tested, 100% sure.

Would you happen to recall what those registry tweaks were? Based on your above comments I think the best I can do is to lower the bit rates and bandwidth. Honestly most of my listening is talk radio and much less music. Even so, I'm older and I can't tell as much about the lose of highs, etc...
I have toned down things in Advanced Configuration Tools - Bluetooth section hoping that this increases reliability.
What I don't understand is why is this apparently so hard to get right? I mean this is not rocket science here! It's merely a connection that is radio based? Can't people code the software correctly! Geeze!

The Rokr has essentially 4 buttons. Power, FM selector, Call pickup and Pause/Play. There are also some combinations. The FM Selector is simply a button to push where the Rokr scans the stations and tells you which station to set your FM radio to. Power is for power, naturally. The Call pickup and Pause/Play are as their names suggest. Pause/Play pauses or plays the media player on the other end of the Bluetooth (through AVRCP) and Call pickup picks up an incoming call. Both of these buttons attempt to talk to the remote Bluetooth device if the connection is not currently established. However since most of the time the problem is that the Bluetooth dropped it's connection (necessitating having to go throught Start: Settings: Bluetooth: Mode: Turn Bluetooth on). Also, turning off the power and turning it back on causes it to try to pair up again, which sometimes work. However, if you currently have it broadcasting to your FM radio and your radio turned up, powering it off kills that connection causing loud static to come out of your radio until you power it back up and re-establish the FM broadcast portion.
I can see if I can screen capture my HTC Touch Diamond with the Bluetooth off in the Bluetooth settings but the Bluetooth indicator actually on in the title bar. Weird state! You should never be in that state with one part saying Bluetooth is on and the other saying Bluetooth is not on!
Finally, i don't know which ROM you are using, but the one i'm running now is the one from the official HTC website, "_HTC Touch Diamond_QMR_RUU_Diamond_HTC_NLD_1.93.404.1_Radio_Signed_Diamond_52.29.25.12_1.00.25.05_Ship.exe".

Do you know of a Widcomm stack for the HTC Touch Diamond? How about a copy of the MS Bluetooth stack? I did turn down the bandwidth/bitrates and hopefully that'll make it more reliable. However it would be nice to have those Bluetooth stacks available to install and play with.

I had seen this program before. Perhaps you can explain how it's supposed to work. Because whenever I run it it does nothing.
I have two HBH-DS970's. I pair them both up to the phone. I can play music but only through one of them. When I run the Bluetooth toggle thing it first plays in the current HBH-DS970 but pretty much out of phase (sounds tinny). If I run the BT Toggle again it briefly (for 1/2 a second) plays on the speaker phone then plays in the same HBH-DS970 but in phase (full bass). The toggle toggles between these two in phase/out of phase sounds with a brief blast on the speaker phone but only in one of the HBH-DS970.
If I power off the HBH-DS970 and establish Bluetooth connections with the other HBH-DS970 and I do the BT Toggle thing again the same thing happens with the second HBH-DS970. It does not transfer the BT from one HBH-DS970 to the other! I suspect it wouldn't transfer the BT from an HBH-DS970 to the Rokr either.
I don't get it! What's this BT Toggle for?

You're correct. They are the same tweaks that are now provided in the advanced configuration tool. Back then, when i just had my Wizard i did not have this tool and i had to go into the registry to change the settings manually (they can be found under \HKLM\Software\Microsoft\Bluetooth\A2DP\Settings).
The most important one is BitPool, i use 58 for the quality of the audio, but since you mentioned you use it to talk radio and not so much listening to music you can set it to 30. You should not experience any buffering skips then.
Then you have MaxSupportedBitPool, which you can delete. I played with changing the settings here but no major effect.
Finally, there is UseJointStereo, to have stereo set it to 1. In the older WM6 BT stacks when set to 0, it would reduce the hissing noise but the audio would be mono.

My MBR-100 uses A2DP, my earpiece HFP. That's why i'm able to use both at the same time. However, you can't use A2DP 2x simultaniously. I was just pointing out that the BT stack of WM6 is capable of using different profiles simultaniously. If your Rokr and your Sony headset use different profiles, you could have used the small BT toggle program to switch easily..
But even if they use different profiles, you can't use the audio output twice at the same time. You can only toggle to wich profile it redirects.

The only thing i can think of, is when the two are too far apart from each other. I did not have any strange disconnects so i don't have the same experience.
You mentioned you are still running the original ROM, and if you have the time it is not a bad idea to upgrade it. I know that in the beginning of WM6 A2DP did not work as well as it does today (i had to tweak then, now it works well with default settings). Also because you mentioned your BT behaves irratically.
The process of upgrading is relatively easy and you will gain a performance boost as well.

The BT toggle app does nothing more than redirect the audio to the next available (connected) device. I use it switch to earpiece, when i answered the phone with the buttons on the Diamond (when i answer calls with the button on the earpiece, it does that automatically).
When listening to music, i can switch the audio between the earpiece and the car stereo.
So i figured, maybe you could use it in the same way, when you walk to the car enjoy the music trough your headset, and when you are in your car, click whatever button it is on your Rokr that activates the connection and simply click the icon to change the audio from your headset to the Rokr.
edit :
After reading your story about your Rokr again, i begin to believe there is something wrong with the BT portion in your Diamond (connection dropping, having different icons say different things about BT state). Your Rokr wants to make the connection by pressing the button, and that is how easy it should be.
That's how it works for me. I would recommend upgrading to the latest ROM, i downloaded it from the official HTC website.
I mentioned the exact filename with version number a few posts ago.
That way, you will be sure that software (BT stack) is o.k., i can confirm that in my case it does what it is supposed to...

But my point is that the HBH-DS970 can do both. IOW while listening to music (or talk radio), if a call comes in then you simply hit the little call switch on the mic and the music stops and you answer the phone. Talk on the call and listen in both ears then hit the little call switch on the mic and wham you're back to your music or program material. It's really quite cool! When it works that is! Or, if you weren't listening to music and a call comes in simply put the earbuds in (they conveniently fall along the necklace of the HBH-DS970) and talk. IOW, given this, what would I need or want a mono earpiece that just answers calls when this will do both?
My MBR-100 uses A2DP, my earpiece HFP. That's why i'm able to use both at the same time. However, you can't use A2DP 2x simultaniously. I was just pointing out that the BT stack of WM6 is capable of using different profiles simultaniously. If your Rokr and your Sony headset use different profiles, you could have used the small BT toggle program to switch easily..

Define "different profiles" in this context...
But even if they use different profiles, you can't use the audio output twice at the same time. You can only toggle to wich profile it redirects.

That may be what the BT Toggle does and it may be that you cannot use two A2DP stereo outputs at the same time. What I'm asking is "Why not? Why this seemingly artificial limitation? Is is security concern? Did nobody think anybody might want to do this? Is it a hardware limitation? Is it a Bluetooth 2.x limitation?". It just seems silly to me to put a limitation like this for seemingly no particular reason. Ya know some people might want to actually share their music in like real time!
You mentioned you are still running the original ROM, and if you have the time it is not a bad idea to upgrade it. I know that in the beginning of WM6 A2DP did not work as well as it does today (i had to tweak then, now it works well with default settings). Also because you mentioned your BT behaves irratically.
The process of upgrading is relatively easy and you will gain a performance boost as well.

I've done some ROM updates back with the old PPC-6700. Yes there were better but they also weren't supported. I'm with (crappy) Sprint but I think all carriers shy away from you burning in a new ROM on them. They only support you not touching anything like that. In fact, IIRC the original Sprint ROM for the PPC-6700 didn't even support stereo Bluetooth at all! It was only after installing the Widcomm stack that I was able to get stereo BT working!
And that's part of the scary part for me. Originally, the first BT stack I installed worked fairly well with MS Voice Command actually working and when a call came in while I was listening to music, it would properly pause the music, answer the phone then return to the music. But that lasted only a short time. For most of my 2 years with that phone the BT would not stop the music to answer the phone.
The current Sprint derived HTC Touch Diamond ROM works WRT the BT behaving properly for stuff like that. The only real problem I'm having is with the dropping of the connection. So if I go to a new ROM and that breaks... well I don't want that happening. Perhaps if you could point me to the original Sprint ROM so I can get back to where I'm currently at I would venture into newer ROMs.
But another thing that would make me go for the new ROMs is if I could get rid of the god awful Sprint Music Player (SMP or actually the HTC Audio Manager and its Today plugin)! This thing sucks! I usually use Pocket Player however the god damned SMP steals the AVRCP controls such that Pocket Player cannot get them. So I can't use Pocket Player and then have the Play/Pause button on my HBH-DS970 play or pause the SMP! You end up having two audio streams playing at the same time and the pause button does not pause Pocket Player! If there's a ROM out there that removes the silly SMP then I'm all ears!
Since i had my Diamond i never had problems with BT so i didn't search for that. I did save some of the stacks i experimented with when i had my Wizard, but i dont know if they will work on te Diamond... If you can't find anything on this forum, let me know and i will post the cab's for you.
But again, i don't know if they will work on te Diamond!v

I'm a little leary replacing the BT stack that's currently working pretty good (aside from the dropping problem) unless I can assure myself that I can re-install it if the new one doesn't work.
Oh and let me say MusicMaster, you've been very helpful so far. Thanks.
TheMusicMaster said:
The BT toggle app does nothing more than redirect the audio to the next available (connected) device. I use it switch to earpiece, when i answered the phone with the buttons on the Diamond (when i answer calls with the button on the earpiece, it does that automatically).
When listening to music, i can switch the audio between the earpiece and the car stereo.
So i figured, maybe you could use it in the same way, when you walk to the car enjoy the music trough your headset, and when you are in your car, click whatever button it is on your Rokr that activates the connection and simply click the icon to change the audio from your headset to the Rokr.
Click to expand...
Click to collapse
I don't think this will work this way for me. From what I could see the Rokr will not pick up the BT from the HBH-DS970 until and unless I power off the HBH-DS970. Just like my second HBH-DS970 could not get the BT passed to it until the first HBH-DS970 was powered off. But I'll go and check this out...
edit :
After reading your story about your Rokr again, i begin to believe there is something wrong with the BT portion in your Diamond (connection dropping, having different icons say different things about BT state). Your Rokr wants to make the connection by pressing the button, and that is how easy it should be.
That's how it works for me. I would recommend upgrading to the latest ROM, i downloaded it from the official HTC website.

I think that perhaps your situation is different. You mentioned that your "MBR-100 uses A2DP, my earpiece HFP". Yet AFAICT my HBH-DS970 uses A2DP and the Rokr also uses A2DP. Both are attempting to receive stereo music.

I meant, e.g. if your headset used HFP and your Rokr A2DP, they could be connected at the same time. Now i read in your post they both use A2DP so the whole toggling trough different profiles solution is off the table..

I don't know the reason behind that (share music in real time would be awesome, though) but i can think of one technical limitation, and that is bandwith.
If you set the bitrate too high you wil experience skips. When i discovered the highest possible setting without skipping, i even had to set it a bit lower because i use my earpiece simultaniously. The music played without skips, but as soon as i would turn the earpiece on it would start skipping.
It is also impossible to stream audio and transfer data via PAN. Both the connections are o.k. but te A2DP stream would stop until the data is transferred.
So i assume there would not be enough bandwith to stream audio to multiple devices..

Heh, i use Pocket Player as well Unfortunately i don't use AVRCP but i think that is a software issue. I've read somewhere else on this forum users having the same complaint. Did not see a solution there..
Question : is this sprint player integrated in TF3D? There is a tweak tool out there to remove tabs. I removed the music player tab.
The other solution would be to go for the updated ROM from HTC. I understand your worries concerning support after flashing but i have flashed every phone i had and had never any problems.. My (flashed) Wizard broke down once, and T-Mobile (my carrier then) repaired it without any cost..
I must say i don't know how Sprint handles these things (i live in Europe).
A good thing is it's a ROM upgrade from the official HTC website so i don't think you have to change SPL (which from what i heard, is the warranty-voiding process). But anyway the sprint player is NOT included..

You can always perform a hard reset, the MS BT stack will be intact.. (maybe use Sprite backup before you install another stack, it works really well (i don't know if you have the program, it came with my Diamond))

True, the idea of using the BT audio toggle is definately not going to work for you.
But, our situation has similarities! Like i mentioned, i use two MBR-100 devices. When one runs out of energy, i use the second one. They both use AD2P!
The process of changing the two is really simple, and i believe it should be as simple as that with your two A2DP devices.
This is how it goes wen i change the two :
- music is playing on my Diamond, sound goes to MBR100 #1.
- i power off MBR100 #1 (or it runs out of energy), A2DP connection closes, music keeps playing but now from the phone speaker.
- i power up MBR100 #2, press the button on it, it establishes A2DP connection and the music keeps playing, sound goes to MBR100 #2.
Simple as that, i don't even have to awake or touch the Diamond. Now i believe it should be possible that it is that easy for you too..

This doesn't work. The "plugin" sounds like the plugin that even Conduit already offers for older versions of Pocket Player. And the new version of Pocket Player has this already built in. The problem is it's ineffective as something in the HTC implementation is usurping the AVRCP thing. See Bluetooth in 3.7 on Conduit's forum and AVRCP not working in PocketMusic and PocketPlayer ! here in this forum.
It may be that disabling the Sprint Music Player (really HTC Audio Manager) tab and guts will solve the problem and that may be in the HTC original ROM. I don't think you gave a direct pointer but I will research this later tonight.
Pointers to how to do a hard reset on the HTC Touch Diamond such that I can get back to the original ROM from Sprint would be appreciated (I seem to recall if you burn a ROM onto the phone then a hard reset goes off of that burned ROM not the original ROM. And no I have no backup product).
This is the link to the thread where you can download the TF3D Config program to remove the music tab.
You can perform a hard reset by pressing the vol-down key and enter button simultaniously (then power up), but you can only use this to restore the current ROM you are running to its initial state.
So you are right, you can use a hard reset to restore your Diamond to factory settings now (might be useful if you just want to experiment with other BT stacks and end up with the original BT stack not working), but if you flash your phone you can't go back to its original state unless you have that factory ROM.
But, since the ROM i mentioned comes from the official HTC site, i guess when it comes to support if you ever need it, you can always put on your innocent face and say "was i not supposed to do that?"

You're in Europe aren't you? Things are different here in the States. Sprint doesn't take to kindly to you saying "was I not supposed to do that?". Their answer would be "of course you can't do that - your warantee is now void".
It's clear to me that the HTC phone and the Sprint branded phone are not one in the same. For one the back is different. Two, it's branded with the Sprint logo all over it! 3, it has the "Sprint Music Store", something I highly doubt a European HTC Touch Diamond would have. Forth, there is no radio! None, nada, caput! I downloaded the Radio cab and installed it - even hooked up the wired headset since it needs that for an antennae - nada. I also saw postings that Sprint's phone doesn't do radio. Now I could complain to Sprint saying the HTC site boasted of an FM radio to which I'm sure Sprint will merely say "Well that's HTC. We are not HTC. Our site and our advertising never said anything about an FM Radio". Additionally the time on the home page is different. Finally, tools such as TF3D Config tool just bombs out as noted above. No, to me it's clear the Sprint phone is not the same as the HTC Touch Diamond from HTC itself.
It's not like I haven't been downloading and installing things that obviously Sprint wouldn't like. I got things like a Transparent Clock, Remove [Sprint] Logo, Flip Clock and Advanced Config and TF3D Config. I even played with downloading the HTC Audio Manager and the HTC Audio Manager Today Plugin. All of these things were cab files that I could easily, and relatively safely install, try and uninstall should it not work correctly. I'd love to "install a new Bluetooth stack" if that were doable. But burning a whole new ROM and permanently severing any hope of "support" from Sprint - voiding the warantee... Well I guess I'm not exactly there yet but you're right - I'll probably have to end up doing that.
Still it would be nice if I could get the original Sprint ROM and the HTC ROM and play around with at least a little hope of being able to go back.
Oh, and BTW, aside from the "Volume Down and Enter while powering up" thing, I recall having some .exe that I ran on my PC that did the burning of the ROM to the phone. IIRC there was some other sequence to get it to receive the ROM. Ah yes I documented this on my blog:
Once you have a ROM you run the installation process. First you need to get your phone in "Bootloader" mode. This means, on my phone, that you hold down the power and voice record buttons at the same time while you perform a soft reset. Now here's the tricky part: The screen appears to be black but if you look really carefully you'll notice it says "Serial". You'll probably have to look at it in the light and move the phone from side to side. Why the secretly displayed with no backlight screen is beyond me.
Click to expand...

What's that sequence for the HTC Touch Diamond? And do these ROMs then install to this phone in "bootloader" mode?
O.k., i didn't realize your Diamond was different from mine. I figured, if we both have the same hard and software, and it works here, it has to work for you too.. When i was with T-Mobile, i got a branded HTC Touch, but this branding was nothing else then they put their T-Mobile logo on the device, and they modified WM6 so that everything has pink icons (no wonder i flashed it whitin a week ).
But the hardware was identical to original HTC devices.
I recently moved to a less urban part of the country, where there is no T-Mobile reception so i had to switch carrier, and when i switched i got the Diamond. This new carrier was Telfort, and they didn't even brand or lock the device. The only reason i upgraded the software is because i read the performance would be better (and it is )
So i see now, your situation is really different..

One thing you can do before you decide to flash is see at HTC's website if there is an update for your device.
Before you can download the ROM, you have to fill in the serial number from your Diamond. Then you will know if they even have an update for your device.
When you fill in the serial number you will automatically get the right update. I even got the update in my own language (i'm dutch).

Oh, another thing, BT related. It's been frustrating but lately when I get a call I cannot answer it with the BT headset! Looking at the phone and trying Menu: Turn Hands Free On is grayed out! Quite honestly I'm no longer used to having to hold a phone up to my ear! It's damn inconvenient! Just this weekend my sister called and I was outside detailing my car a bit listening to a radio show. I go to answer the phone and it drops the BT connection! So I'm talking to her and I cannot continue my work - my car will have to wait. So I go back inside and turn on the speaker phone to listen and talk while I fiddle with the Bluetooth settings attempting to get the damn Turn Hands Free On thing to work. I turn off BT on the phone. I turn of the BT headset I have. I turn them both one - nada. I go into Settings: Bluetooth: Device and Refresh to see if the Hands Free got toggled off. Nope. I delete the device and re-add/re-pair it. Nothing. Nothing I did would get it so that I could switch to using my BT headset so I could get back to doing my car. What causes Turn Hands Free On to gray out when BT is on and the device has Hands Free toggled on? I mean shouldn't that mean that I can use Hands Free from that device? BTW, of course, a soft reset of the phone fixes the problem but by then it's too late! It's damn frustrating. And god damn it, I ask you, how hard is it to get BT working correctly?!?
Now when I get a phone call my music stops, the BT disconnects and the phone starts ringing on the speaker. I answer it and the screen goes blank and the speaker phone kicks in. Damn this is convenient! This is exactly what I want my phone to do! It anticipates my every need! NOT!!!
(Now I know somewhere there was some setting to turn off the screen when the phone picks up but I can't find it anymore. And the dropping of the BT and instead automatically going to the speaker phone - so everybody else can hear - is just unacceptable! Really, this should not be this hard! Designers of phones and their UI's - WAKE UP! Geeze!).
Click to expand...
Click to collapse
OK, I'm fed up. I'd say that just today alone I had to turn on Bluetooth after it turning itself off like 15 times today. Just going to the grocery store whenever I hit the pause button then attempted to resume playback, BT was lost - 3 times on the less than 1/2 mile drive back to my house! The HTC ROM and no support from Sprint can't be any worse!!!
I will need to spend some time getting the ROM and then preparing properly to take this step. Usually I'd do this on the weekend but my daughter's in town for the weekend so it might be the week after. I've heard about the HTC Original ROM but are there any better ones? Remember, BT reliability is high on my list. And if I can find a ROM that allows me to remove - completely gut - the HTC Audio Manager tab so that Pocket Player can have a chance at AVRCP then I'm all ears!!!
I promise to write a full report on my experiences, hopefully documenting the problems I currently have and the hopeful solutions the new ROM will give - or just the new set of problems which is probably more likely...
This has almost gotten me to the point of writing my own Bluetooth stack though something tells me that the reason it works so badly now is probably because the Bluetooth specification is overly complicated and not very well defined...
And thanks everyone for listening to my ranting and not coming down too hard on me. I'm frustrated and sometimes vent. Thanks for understanding...
Nexus 7 Head-unit Install
Hi all, long time reader, first time poster. I'm working on a Nexus 7 Car Head-unit install, and figured I would post my working through the install, hardware, software, and kinda just help all the tons of people I see out there who have the same idea, but just have no idea how to go about it.
This is ment to be half a tutorial (once everything is done) and half a brainstorming to give me idea's for things I haven't thought of or considered. I'll be coming back and updating this OP with pictures, and the build as it gets worked on.
Goals of the Install
I want to be able to run my entire car off the Nexus. I have already set up wifi tethering from my S3 to get internet into the Nexus, and thus open up a realm of possibilities. Necessary features are Nav, and Music. I rarely call from my car, but in car calling would be a nice feature to have as well. I also go out to the track ever now and again, and adding car stats (boost, RPM logging, acceleration, mapping) would be great. The biggest reason to do the install is that one the hardware is configured, you literally have a ultimately customizable setup that will take years to outdate.
The Hardware
1 x 2003 Subaru WRX
1 x Nexus 7
1 x Samsung Galaxy S3 (T-Mobile)
1 x MRX-V60 - Alpine 5-Channel Subwoofer Amplifier
1 x 7 Channel Equalizer
lots of hacked wiring
The Software
This is where I would love some feedback on on what I may be missing, better solutions to what I have suggested, and just some general awesome idea's!
Music:
Pandora, Play Music, DI.fm, Soundcloud, Radio.com
In Car Phone/Text:
Talkatak, Google Voice
OBDII Support: (Future Project)
Right now this is not a nessiacty as the hardware to do this could get very tricky. However I know I can read from the OBDII port with a bluetooth OBDII dongel and an app like Torque Lite. However I do own a tatrix cable, and am considering if it would be possible to go from the USB to the tablet, and find an app/write one what allows for the tablet to control the car in real time.
Nav:
Google Navigation, Local
Track Apps:
aLapHD
The Two Builds
There are two ways to go about this. The first would be the simple and easy way which is to hack together a charger wired to the power source of the car, and use that to keep the tablet charged. Then run a 3.5mm audio into the amp, and have sound run from there. There are a few issues with that. 1. There will be no volume control, as the Tablet's buttons will be part of the center console. I suppose I can run a controller to the amp, that will let me adjust volume. 2. This will not allow for the possibility of adding OBDII support.
The second option is to purchase a micro USB dock that does audio out. Hack it apart, and run the audio to the amp, and the power to the power. This would be necessary if I want to do a full USB ODBII connection (I believe, please tell me if I'm wrong), and would be much "cleaner" when it comes time to take the tablet out of the car for any reason (hardwire sync, parking in the "ghetto").
What I need Help with
Have any idea's. Tried something similar and have some tips. Have suggestions for apps, hardware configurations I haven't listed, or just generally want to say "sick man". Please let me know. I would love to have some people who are also interested in doing this join in on my build, and we can work together to eliminate any issues to make tablet installs easier. I will be coming back and updating this OP throughout the entire process so please look for updates!
Thanks All!
(reserved for pics)
Check out a half-DIN equalizer or crossover to solve your volume, fading, equalizing concerns... can't post a link because this is first post!
I'd like do do this in the future... I hope someone comes out with a custom set of apps that make this really cool and easy... maybe even a custom ROM.
Basically what I'd want out of this is:
Auto-on with power. Auto off after 10 minutes of no power. FM radio tuner. Maybe the ability to connect a rear-view camera (wifi?). Bluetooth OBDII would be good enough for me.
I'd also appreciate the ability to connect to at least one camera and use it as a DVR, but I think that it would probably be beyond feasibility with the Nexus 7...
What I really want to see is the ability for the Nexus to be a full Bluetooth head unit. I want it to pair with my phone for both internet (already do this, works great) and have it act as a headset essentially. This is the part that appears to not exist anywhere. The ability for the Android Tablet to act as a hands free device. I mean if a car stereo can fully integrate with your phone read your address book, start and answer calls hands free, stream music, everything from your phone then why the heck not the tablet! Someone needs to write the BT stack that can handle that. Apparently it doesn't exist for android. It exists for Windows, but not Android. That is just wrong. Are there any car stereo head units running Android as their OS? If so can someone dump their rom so we can see what all it can do for a project like this?
I really want this!
I have had mine in the dash for a couple weeks now, streaming Bluetooth to the radio which I relocated, also using NFC sticker to turn on WiFi, bluetooth , set audio volume, screen brightness and start playing music. Tasker to put unit into car mode, its sick! I'll be following, really interested to see what you come up with. My car is N 06 altima and the Nexus 7 fits almost like a glove where factory stereo use to be.

If anyone can post on his site, tell him to connect two middle pins in usb plug, then it will start charging from the lighter socket.

Does anyone know of a micro USB dock/cable that then splits to power, usb, and audio? I know of one's that will do 2 of the three, but nothing that does all three. Maybe just a USB and power one, and run the audio straight out of the 3.5mm on the N7.
Amp was ordered, and will be here next week. Prelimanary fitment pics coming soon...
Hello, I'm considering permanently mounting a nexus 7 in my car. It seems like the perfect in car device.
With this in mind I have updated my CarHome Ultra app to better accommodate the Nexus 7 screen. I will be posting a new video soon showing it running on the 7.
I've looked at doing this as well, I've always been prevented by the issue of the FM radio. I use the car a lot in places where I get no or poor connection via the phone, but the radio works fine, so loosing it would not be an option as I use the FM radio quite alot.
I've been trying to figure out away to control an FM radio via the Nexus so if anyone out there has any info it would be greatly appreciated.

Load a hand full of mp3s on the device. Then use Tasker to switch to switch to your favorite music player when reception is bad

I am actually currently doing a very similar project with a Nexus 7 and my Nissan 350z
I am planning on installing the Nexus 7 inside my dash (to replace sat nav dash)
HOWEVER
what about routing the power button on the tablet? Because If you cant access the power button the tablet will only get power when the car is on and if you dont use the car for a day or two the tablets battery would go flat and next time you turn on the car the tablet would go into charging mode (screen with charging battery only) and not boot up into android jelly bean.
Theres 2 potential solutions:
1. Open the tablet and wire the power button to a custom one, however on opening it I have found the button is actually a physical push press button and cannot be wired.
2. There is potential to change a file on the android system to tell the tablet to boot up when a charger is plugged in, check these threads:

Here's my install. Kept the factory radio intact, if not using the nexus, everything looks totally stock.

xitech xr7 purchased off amazon over a year ago.

Never had any problems with it.
Despite working in the car industry and loving gadgets and mod-ing...I haven't really seen what people are up to these days in terms of car mods. The Nexus 7 makes so much sense and looks great!
Hey all
Just to add to the discusion;
Radio/DAB
Frontier silicon are the only company that I can find that do an app that can control an external radio and stream it's signal to the tablet as opposed to picking up the signal over the cellular network.
App:
Their page
http://www.frontier-silicon.com/products/software/DOK_App.html
Play store
http://tinyurl.com/d24gwm4
Module:
http://www.frontier-silicon.com/products/modules/briefs/Venice6_PB.pdf
now the problem with this is, aside from building the module in somewhere' the audio out as it feeds out of the module, but I was thinking I could use some form of y split cables near to my amps 'in'.
Media storage and playback
As far as storage for everything video/audio atc and a player to match I was thinking of useing xmbc
http://xbmc.org/
andriod port;
http://forum.xda-developers.com/showthread.php?t=1813089
and pairing this with a WiFi DLNA HDD that I would wire in remoted off (say in the boot)
GPS
For improved gps I was going to use an external bluetooth gps reciver then allow mock locations on the tablet, there are also a few apps that help with this.
This app seems to have good support and a nice help page.
App:http://tinyurl.com/a9s7gvo
An example of a external GPS receiver

Hands Free
The only work round I seem to have found atm though far from perfect is this
http://www.scosche.com/consumer-tech/product/1919
it allows you to to 'cut in' the audio stream, but (can't fins the tread now will keep looking) the guy who was playing round with this was having audio issues.
not an idea solution but workable.
before my mind starts melting again;
How I plan to implement the tablet is to use tasker to wake the tablet when power is supplied then shut of down after, if I disable all kinds of connectivity when tablet shuts down then reactivates when it wakes up everything should run smoothly. Power will be cut because I'll wire in the ignition live, like you do in a stereo anyway, an this shouldn't put a drain on my battery to much, an if the dash build is good it shouldn't be too much of an issue extracting the tablet to hard boot anyway.
Volume and Audio
Volume and audio quality is another issue that needs to be addressed.
http://tinyurl.com/d2zbbnf
Seems like an ok work round.
Another way would be to install a direct in-line volume control as suggested in other threads, and put in an external DAC or hardwired EQ.
On a side note I came across this........ http://www.crutchfield.com/p_773AIRDAC/NuForce-Air-DAC-Receiver.html?tp=59282 ........ although you need to use their plug in senders but I'm sure this can be worked round with the knowledge on this forum, an would provide a very nice solution. then again there are quite a few bluetooth devices around. this probably wouldn't allow for in-line controls though.
well thats it for now, hope this helps push this forward to a working system
ben
nice build thread containing alot of theses ideas;

Which is your favorite color phone case?
After watching a few YouTube videos I now understand that the dual feature of the Note 8 Bluetooth has nothing to do with Bluetooth 5.
From what I've learned, Bluetooth 5 is simply a combination of Classic Bluetooth (2 & 3) coupled with Extended Bluetooth (high range with lesser throughput), which does NOT mean you can expect to crash n your speaker in the house from the garden.
In other words, for the DUAL Bluetooth feature on the Note 8, it would appear that there are in fact two separate BT reciever / transmitters.
Can anyone verify this?
Also, if this is true, how likely will it be that either a software update or an app will be able to take advantage of this, and split stereo channels to two separate Bluetooth speakers, thus giving true stereo sound in the home?

Why I dunno, ATG! That's a pretty good friggin' question about a thousand dollars phone to ask here, on what's arguably the largest collection of handset-technology educated folks on the Internet.
Ohmagosh, let's see what they say...!

Why I don't know, maybe it does have two BT chips in it. I'm going to guess it does. The delay sucks though for sure.
Meh... I'll take any answer I can get at this point just get the discussion going. Can't believe this hasn't been a major discussion topic yet, and I can't find anything about what I'm asking on the web.
The delay can be remedied by changing placement of the phone between the devices. In other words, from what I've read / heard, no matter how different the two speakers are, there's a theoretical distance between each one that is the ideal placement for the phone where they'll be no lag between the two. I've done this in my own house. I relocated a small table in the foyer to get optimum placement between the dining room and living room speakers.
I have yet to try this with identical speakers to check if midway between them is ideal placement for the phone.

My problem isn't the latency it's the dang volumes. Even with the setting. Can't think of it as I haven't tried in a while. But one of my speakers are as quiet as can be the other is blazing loud. I could never get them to even nearly match...
Surely it's only got one Bluetooth chip just allows more than 1 connection.
No different than having your speakers and a watch connected at the same time 2.
Just 2 audio streams at once
What hasn't Bluetooth allowed more than once bt device gonna had before as long as they used different profiles
I have several speakers, and also two of the same model by the same brand, and until now, I could never get then to play at the same time.
Maybe I should just bitter the bullet and buy a system that splits the stereo channel between two speakers after.
Dual Bluetooth feature means that you can connect with two Bluetooth audio devices at same time and music on the phone will be played simultaneously on the both devices. Left audio channel on the first connected, Right audio channel on second connected.
Switch "Dual audio" via 3dots Bluetooth menu.
Only first device can control (pause/play/next/previos) phone's player.
There is no need both devices to be same brand/model.
Bluetooth version of devices is also not important.
All version are backwards compatible with previous versions. So if your phone is v5, first speaker v4, second v2, so all communications will be on v2.
Even v1 Bluetooth support up to 8 devices multiple (serial) connections. One phone connected to 7 others and gaming multiplayer (Nokia N-gage) . But just now manufacturer deside to make two (audio channels) connection.
ChoSmile, I'm failing to understand...
Are you saying they are already separated into left and right audio channels??
dual Bluetooth has nothing to do with channel separation; all it does is allow 2 devices to be connected to your phone via Bluetooth at the same time, listening to the same exact audio stream

I play music through poweramp to 2 phillips bt speakers that can connect together anyways. But it's a pain to connect them like that so I just connect them with the dual bt the phone uses. I know what your talking about with the delay so right away I figured out that after they are paired and music starts playing (delayed of course) I simply force close poweramp, go back in and hit play and..... No delay
I'm using 2x Sony Srs-XB10s which natively support stereo pairing themselves, and I dual audio to a Marley with a cheap iPod dock, bluetooth adapter.
There's a ~1s delay from the Sony's when they're in native-stereo mode.
There's ~0.3s delay when they're attached singularly over Bluetooth. This fluctuates, but usually grows to ~0.8s over 2 minutes, then resets.
It's upsetting the audio can't be delayed per-device manually.
I love the technology though and it excited me I could in theory have 5.1 with this solution (Marley is almost a 2.1) but alas it's not mature enough.
Keenly interested in the progress of this feature! Saves the manufacturer having to implement it, though Sony's, despite the bigger delay, is very very simple and obviously there's no delay between their own 2 speakers.
