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!
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).

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.

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!

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!

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.

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?"

To which another guy said he's having problems and if you look even further down that thread I said "Me 3!". So TF3D Config does not work for us unfortunate Sprint HTC Touch Diamond owners...

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.

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).

No, it's actually quite easy. It is an .exe you run from your desktop when activesync is connected. Click "next" a couple of times, wait +/- 7 mins until the progress bar reaches 100% and you're done... Nice website btw. I see you play the guitar as well

I'll probably end up just flashing to the HTC ROM. Hell most of my updates so far have been to get it to be more HTC-like as they did a nice job (and Sprint has screwed it up). I just need to get some extra spare time if you know how that is....

Thanks. Haven't played guitar in years now. Music's not what it used to be (i.e. respected) or at least not here in the US. Again, different market...
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!).

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...
Has anyone else been unable to make phone calls after connecting to your vehicle's bluetooth? Most of the time, I can make phone calls without issue. Sometimes, I can't even hear the call ring when I'm connected to bluetooth. Occasionally, when I turn my vehicle off, the call goes silent instead of transferring to the earpiece on the phone. The only way I can fix the issue is rebooting the phone. This has become increasingly frustrating for me, since the issue is so inconsistent.
I'm running the stock ROM, rooted and un-encrypted.
Thanks!
Same here
I'm having the exact same problem you are having with my Ford Touch Sync, Bluetooth has work maybe once. At other times only the music over bluetooth has work. But was unable to make hands free calling! I also made my ford touch sync a trusted device, and the problem with connection still continues! Hope someone could provide some suggestions
Stock rooted- TWRP- encryption removed
I am having issues also. Just today, my phone shows I am connected to my Pioneer Navi head unit, and the Pioneer shows connected to my phone. I proceed to make a call. The audio on my radio mutes as it should, and nothing. No ringing, no busy signal nothing. so i hang up and try three more times. on that third retry, i heard the other party faintly, realizing that even though my radio muted and shows BT connected, the call went through the ear speaker on the phone. When I hung up the phone, my radio unmuted.
Last week, I was having issues where i couldnt hear any rings or busy signals. It would be silent for 20 seconds or so, then i hear the other party say "hello".
I honestly thought it was my head unit, since it is about 4 years old. But now I see others with similar issues on other brand bluetooth systems in their cars.

I just got my N6 today and I'm having trouble with My Ford Touch as well. I can get it to pair and play music, but it won't "connect" to my phone. It's odd because my N5 works fine with it. I would assume the N6 wouldn't be different.
We probably have to wait for an update from Ford, which will probably take months...
EDIT: Well I decided to try it again. I deleted the Nexus 6 entry as well as the Nexus 5 entry. Went through the pairing process again and it worked as intended. Not sure what happened the first time.
I ran into the same problem as others where my N5 worked flawlessly with my Ford Sync in my fusion, but the N6 is terrible.
I love the phone, but this is really annoying. I get into the car and sometimes it connects immediately, other times I have to turn off and back on the bluetooth about 3 times for it to finally connect. Very weird. Ford offers an upgrade to my Sync system, but wants $50 to do the upgrade. Pass.
I might try what the other person did and delete all entries for phones and pair it again. Unfortunately, the weather is pretty bad outside, so it might need to wait a short bit.
Has anyone else had luck re-pairing with their car and had reliable connections?
I use Ford Sync.

I use Ford Sync, and everything works as expected. I am Stock and unrooted. I guess it would come down to what version of Sync. Mine is from 2012. No touch screen. I also delete all other entries on the system and start from scratch making sure that the N6 is the main device.
If I can wake up the screen on my own, outgoing calls work fine

I have a Nexus 6 running Benzo ROM (5.1.1) and I have a GPS Nuvi 3580 bluetooth-enabled which I want to use to make calls while driving. I have added this device to my trusted devices so my phone unlocks as soon as it connected to it.
If my phone screen is on, then I'm able to call anyone from the bluetooth device, no issues. But as soon as my screen goes off, I can't make calls and when I switch on the screen on my own, I see a message "Process system isn't responding. Wait or close?"
Irrespective of what I select on this message, the call goes through. But it totally defeats the purpose of handsfree bluetooth mode. Is there something that is not allowing the bluetooth device to wake my phone up.
Also when I receive an incoming call, I see the notification on my GPS but I can't receive the call in one go. It takes multiple calls for it go through. I have also noticed that my bluetooth device keeps disconnecting and connecting without any change on either the phone or the GPS side.

Since I last made that post you quoted, i purchased and installed a 2015 model of the Pioneer AVIC-8100NEX. It has Android Auto, but can be used with the regular Pioneer UI also. I have had no issues anymore with this new radio. Maybe the BT protocol in the radio is newer? Im not that tech savvy to know. But the 2015 radio had no issues with BT calls anymore, on Pioneer's UI or Android Auto's UI.
My gut tells me this maybe a lollipop issue in general.
*On a call
*Another call comes in
*Nexus 6 switches audio source to handset
*Call is no longer on my Bluetooth earpiece
This can happen too when email / SMS arrives. I read about a lot of car BT based issues...this is just in the headset now.
Anyone out there feeling this too?
There is a problem with Bluetooth in Lollipop or the Nexus 6

Not many people use BT in their car or daily life at this point in time. Can't tell you how many people I see driving around with a phone in one hand and a steering wheel in the other. Kind of like people here in the USA that don't use cruise control on the highway when clearly you know that their car has it. But I've been hands free in cars for over six years in fact since the HTC HD2 came out. I realized at that point, that to be safe one must use BT and have equipment in car to support this. It's becoming a law in most states in the USA but not all and is not enforced by law as much as it should be, but those times are going to change. There are some forums on the web that talk about bluetooth in lollipop and many of them are confused and think they know what the problem is, but none have proved it yet. There are also other sources that claim BT is on it's way out, I don't know about that. But yes, there are some weird things happening with bluetooth if you use it a lot. I don't know what the answer may be to your problem but you might want to try a search on google to find out more information about this issue. Good luck.

Interesting perspective and ty for taking the time to post this.
Back to the point though; anyone out there having these types of specific challenges with Bluetooth on the N6 as I described above? It really makes this phone unusable for me @ work.
Yes, I also use BT in my vehicle. It used to connect through my car speakers automatically, but now im finding that when making/receiving a call, I need to manually tell it to switch to car speakers. I mean, why the hell would my car speakers stop playing regular radio when a call comes in and to make me still use my handset to talk/listen?having to manually switch to car speakers is dangerouse while on the freeway.

I was experiencing something similar.
I had a 2009 model Pioneer AVIC-x910BT headunit in my truck. And bluetooth worked fine until I got my Nexus 6 (coming from a Nexus 5 and Nexus 4). The Nexus 6 would mute my car audio properly, but when I picked up the phone, the phonecall was on the phone and not the car speakers.
I have the same car, but now I have a 2015 model Pioneer AVIC-8100NEX with Android Auto, and have not had one BT issue yet. I am assuming that the issue was either the N6 or Lollipop5.0 was having issues with the older BT technology my old radio used. Now that I have the newer radio, no call issues yet.

Could you share the model and make or the car?
to confirm my understanding,the call audio was on phone speaker and you had to manually select the it every time?
Was this working in the past for you?
Does this happen for every call or only during multiparty call?
I am now using a different BT headset, Jabra, and the model is at least a year old. I think I am going to look for a completely new model of bluetooth headset / earpiece that came on the market much more recently and see if this makes a difference.
I have been using a wired headset to avoid these challenges, but very much miss hands free use for phone calls. Anyone else feeling this issue out there?

It has happened to me as well. I use a Jabra Tour BT speakerphone, while having music streamed via a BB BT gateway to my car speakers When on the phone and another call / sms /email comes in, the phone connection to Jabra Tour is dropped, I have to manually reconnect (but after reconnecting to Jabra the phone call ends, somehow the media stream switches from BB gateway to Jabra = more manual switching). Unsafe to be doing this on a highway. My Galaxy Note 3 and prior to that Galaxy S3 worked perfectly well with the same setup.
I understand that Nexus 6 takes advantage of the new BT tech, but it should have been made backwards compatible with the older BT devices.
