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.
I bought a pair of sennheiser hd558 yesterday (for home use on my laptop) and i am surprised how they sound hooked up on my SGS (with voodoo to get everything out of the wolfson chip), the only problem is that my laptop has a onboard sound chip (Realtek ALC883) wich gives a crappy output.
As i am a student on a kind of tight budget i was having some "brainfarts" about making the SGS think it is a soundcard while connected to the laptop. That way i can play everything on the laptop as usuall and the output goes thru the SGS.
Is this possible ? If it is, is there someone willing to help me do it ? Because there is very little information available about this (only about wireless and i dont want to send a laggy stream to my phone with the possibility of losing quality).
I have already looked at VLC/UPnP options but the only thing available seems to be a bunch of players i can install on my SGS wich stream (thus thru wifi wich i DONT want) the files off my laptop.
Basically, i want my SGS to act as a fully operational usb soundcard for my laptop when i tell it to do so.
PS: I use foobar2000 as music player, setting this up with ASIO4ALL would solve the problem of having a transmitter, the problem still left is the phone accepting it.
Wow now aren't you expecting too much out of your SGS!
Anyways I don't even know if something like this is even possible... but it would be quite interesting if it could, but I highly doubt it!
Hi,
I have a new car with a phone car kit (VW RNS510), and I'm not able to connect each other. I would like to know the supported profiles of this phone?
With stock ROM and CM 7.2
I don't know if my car use rSAP or HFP profile...
I think it's HFP but I'am surprised that no one of the 2 Roms I tested make the phone compatible...
Thanks.

Phone calls on the move
And making phone calls on the move will become even safer and more convenient in future. With the optional Bluetooth mobile phone preparation, you can use the Phone button and touch-screen to access the telephone menu directly, scroll through the phone book, and even enter numbers on the display. (This system is only compatible with rSAP mobile telephones - please ask your local retailer for more information.)
So, wherever you want to go in your Volkswagen, and whatever you'd like to listen to on the way, the RNS 510 is waiting for your command.
* The number of speakers may vary by model

I think rSap is just for getting contacts from your phone.
I recently installed a new head unit in my car, Kenwood DDX470, which I believe is compatible with the revolution. The phones bluetooth connects and allows the track controls to control music, both on spotify and all access. I switched from spotify to all access because there was a 4 steps process that had to be followed in order to successfully sync the bluetooth, and because I heard that spotify was not necessarily very compatible with android devices, and because I heard that all access might show the track information once linked up. I'm pretty sure the phone has the ability to transmit metadata, track info, because it does so no problem with music stored on the device, but unfortunately it does not do so when streaming through all access or spotify.
I saw that there is a link to install a 3rd party app for the samsung SG3 and tab but it didn't work for my phone. I've talked to all access support, lg support, best buy, and verizon, and there appears to be no solution. I know that transmitting metadata is possible while streaming, since my brother is able to transmit this information on his iphone for both music streaming subscriptions. I'm, assuming this has something to do with the blue tooth stack of the phone, but I really don't know. Any insight into this problem would be great. I travel a lot for work and am a bit of an audiophile and this is the last problem I am having getting the system linked up properly. Hopefully one of the genius' at xda will have a solution. Thanks!!

First off, the iphone is a whole other animal when it comes to car audio. You cannot compare what you do with an apple product in your car to any other device. Period. Now, second, I have never been able to get meta data to show through bt on the revo. I have had this phone for 2 christmas's and can't recall ever seeing meta data displayed.
Pandora and Spotify work absolutely flawless on my wifes jvc w/o metadata. You could try and search the playstore for a manufacturer app for the radio. I know pioneer, jvc, sony have them. See if that helps. But most likely, you will have to upgrade your phone to get that to work.
I've been a car audio installer for over 10 yrs and android is the blacksheep of the car audio world. Now, the pioneer app radio, through hdmi, works flawlessly with the revo. You can even get screen mirroring to out put the revo's display to your other monitors if you have them. :victory:
Hey guys
So I recently got the Nokia Lumia 1020 after being an android user since day one. Rooted and everything
I have couple of issues and questions that have arise since then.
1. How can I change the search button to bring up google instead of bing? I have read that you have to change your language to Russia but I would not want to do that
2. With my Note 3, HTC one and other previous android devices, I was able to use maps with speech and use the FM radio on my deck together. Android would just mute the FM radio and give me the next direction.
With WP8, it seems like I have to select bluetooth source in order for speech to work, however I can no longer listen to the radio at the same time. Is there a fix/workaround for this?
3. NFC tags.. I recently bought a bunch.. however I noticed that you can't have the nfc tags to change the settings but just launch the settings app? So I would need 3 NFC tags to turn off BT, turn off wifi and enable gps? Seems..... any fix?
Thanks

1: Basically not possible until we "root" the 1020. Maybe if a bootloader exploit is found. Otherwise, only devices sold in markets where Bing doesn't have much presence - such as Russia, I guess - support that option. You can install apps for other search engines, but the button is sort of "hard-coded" to the Bing app.
2: WP7 used the Headset mode of Bluetooth (Hands-Free Profile) for driving directions, but that was built into the OS. Apparently Here Drive can't or won't do that (I consider this a regression, since my car doesn't support the audio profile) so the car needs to be using BT audio (A2DP, I think) to give directions. However, as a work-around, you can of course play media *from the phone* and it should work fine (it will be muted while directions are spoken). Whether you use internally stored MP3s, streaming music from the built-in Xbox Music (formerly Zune Pass), one of many apps (such as Pandora), or the phone's built-in FM receiver (requires that headphone wires be connected, since that's what it uses as an antenna, but otherwise possible), you can have your music and directions both.
3: Yeah, for reasons of their own, Microsoft hasn't exposed any way for third-party developers to toggle various settings directly. With that said, though... There's basically no need to turn either BT or WiFi off; they draw extremely little power when not in use (and by default, WiFi turns off while the screen is off and there's no external power anyhow). As for GPS, unlike Android's incomprehensibly wasteful approach, on WP8 it is *always* inactive unless an app or OS feature is explicitly using it, so as long as you remember to close the navigation app when you're done with it, there's no need to manually turn off location services.
Hope that helps.

Thanks for 1 & 3
However with #2, I would like to have my USB that is plugged into my car deck AND driving directions at the same time. With android this is possible... but not with WP8
What? I must be misunderstanding you, because there's no problem at all with having USB plugged in while getting directions. Or did you mean you're getting the music off the USB (you said radio before, which the phone is capable of doing by itself) and hence the USB is a different input that the BT?
My usual approach in my car is cigarette lighter -> USB adapter -> phone -> ripping cable (I'd use BT if my car would do it for music) -> car stereo AUX port, and that works fine for getting both music and directions. Swap out the aux port and the ripping cable for Bluetooth and it will still work fine (as I've found when I had to rent cars).
That's correct, my deck has a Bluetooth source as well as a USB source.
I have to select Bluetooth source in order to get voice directions to the car speakers but if I select USB source the voice navigation no longer works
Yeah, that's a pain. Is there some reason you can't play your music/audiobooks/podcasts/whatever through the phone, though? Yeah, it's annoying to need to change what works, but on the plus side, it's all your media on one fewer device than you're using now.
