Hi all,
I've just bought my first HTC unit ever (Kaiser), which is also my first Windows Mobile Phone (I used PocketPCs since 2001 but with no integrated phone so far), and it seems to have a lot of issues in the areas of "regular phone" functionality.
However, the one that is really freaking me out so far is the whole "Bluetooth audio" area. I'm just wondering whether I would ever be able to get what I want or am I asking too much.
I have 3 Bluetooth audio devices, all of them are dual Headset/Headphone ones: in-car fixed Motorola T605, Jabra BT8010 and Plantronics 590. Now, naturally, I want to use the T605 in the car, Jabra for phone calls only throughout the day and for music occasionally, and Plantronics when I'm in the gym, for both music and occasional incoming phone calls.
I had all this working flawlessly with my SonyEricsson K800i phone: each device connected to the phone automatically when powered up and automatically took over both Headset and Headphone functions. The only minor problem was reconnecting Jabra when stepping out of the car, which required only a short tap on the button.
Now, with Kaiser, things are much more complicated. When a device (any of them) is connected to the phone, both as Headset and Headphones, it works mostly OK, although sometimes there is a problem of sound not coming through the device when an incoming call was answered while playing music. The music is suspended OK, but the sound comes from the phone speaker instead of the respective Bluetooth device. This happens from time to time, not always.
But the biggest problem is the initial connection of a device after another one has already been connected. When I enter my car and fire up the engine, I want the T605 to automatically connect to the phone even if Jabra has already been connected. This I was unable to achieve. Instead, I have to manually disconnect Jabra (by powering it off or temporarily powering off Bluetooth on the phone) and then manually connect the phone with the T605, for both Headset and Wireless Music (two actions required!). Now, for me, this is unacceptable.
Moreover, when I arrive to a destination and want to step out of the car, I have to manually reconnect my Jabra to the Kaiser, again, through the phone’s Bluetooth settings as described above. A short tap on Jabra’s button no longer works for this purpose, in opposite to SE K800i.
Making the long story short, this is completely unacceptable behavior for me, and I haven’t found so far a way to make it the way I need it.
Any advices?

Have you tried the Bluetooth fix on HTC's website?
Asking is easy, searching is hard work for some people it seems. No offence..
I'm using Schap's ROM which is supposed to have this fix built-in.

Ahh. didn't see that in your first post..
I think you are suffering the same prob as many. Every time a BT device comes out, it never seems to work with what we had before. BT protocols are NOT fixed (The IEEE STILL have not fully implemented a specific proto!), they change faster than we change our devices.
As I said before (without meaning any offence) search the whole forum, many threads have been out on this subject and some advice/fixes or equipment references are out there.
Well, I did search these forums and haven't seen someone referring to the same kind of problems I'm having.
Now, regarding your comment about variety of BT devices... I don't buy that. My SE K800i is 1 year old and works perfectly with this combination of devices.
I have pretty extensive experience with Broadcom/Widcomm BT stack on PC and older models of PocketPC (the one I have is IPAQ 5555) and I suspect these foes are direct derivatives from the fact Kaiser uses MS BT stack, which is much inferior. However, it seems nobody was able to make Broadcom/Widcomm stack work on Kaiser so far...

OK, I'm sorry if you don't. I only tried to help. Seem's you've asked a question and have already formed an opinion to it!!!
I have personal experience of Sony's proprietory connection limitations.
My BT works fine on all my devices....will leave you to others.
Looks like I found a partial solution which makes my life almost perfect...
It seems the real problem is taking over Kaiser from a previously connected device. So, if I switch my Jabra off several seconds before I fire up my car's engine, my T605 is able to connect to it. Same goes the other way around, I can turn off the car engine and then fire up the Jabra several seconds later. In this case all is good.
Looks like the MS BT stack is still ill-implemented though, as, for example, when in active Wireless Music BT connection, the device is unable to discover any other Bluetooth devices or to connect to other device's BT serial interface, which makes using external GPS devices difficult.
This could be a problem for me since my car (Citroen C5) has special anti-radiation coating on its windshield which quite effectively screens the satellite signals. Therefore I came up with a solution of having a BT GPS device permanently located in the car (actually, in the driver's seat back pocket) hardwired to the mains as well as to an external GPS antenna. This setup is effectively beating both reception and start-up time problems.
With Kaiser’s limitation on simultaneous BT connections I’m unable to use this setup anymore. Yes, I could bypass using an additional GPS device by connecting the external antenna to Kaiser’s internal GPS, but this looks like a cumbersome solution as I couldn’t find a Kaiser-compatible mounting with a socket for hardwiring an external GPS antenna.
Luckily for me, I still have my old IPAQ loaded with GPS software which I prefer to use for navigation anyway thanks to its significantly bigger screen

Glad to here you have a resolution (albeit a partial one).
Just one thing, why would you want to connect to an external BT GPS at the same time as your car kit? Can't you get a good enough signal on the internal GPS or is there another reason?

Yes, that's what I wrote in my post above. This antiradiation coating is a real satellite signal killer...
But, IMO, Kaiser's screen is too small for in-car navigation anyway, so having a dedicated unit is always a plus

Sorry, blind AND stupid!
Yes I agree the screen is too small for general use. I have a dedicated GPS in the car and only use the TyTnII as a temporary routefinder whenever needed.
A number of people have mentioned having issues with A2DP streaming on the Nexus.
I just found out something interesting... I've been getting annoying skips in music when playing audio to my car stereo, so after experimenting I've found:-
Open bluetooth settings, select headunit, enter pin, allow phonebook access and for the duration of that connection I get perfect audio.
Turn off either the headunit or phone, or both and allow them to connect again, then audio skips...
Open bluetooth settings, select headunit, unpair, select headunit, enter pin, allow phonebook access and for the duration of that connection, once again I get perfect audio.
The only thing I can think of is that the good connection is initiated by the N1 and the bad one by the headunit when it connects to the N1 at startup. Maybe capability negotiation problem? Maybe N1 selects a lower bitrate when it connects than the headunit does when it connects, any ideas? Is it possible to tweak the N1 to restrict the connection parameters?

I use a HT820 by Motorola and do not have any issues with skipping.
Started stock, then CM, now froyo. no issues on any of these roms.
That's great, but whilst bluetooth is a standard, some manufacturers get things wrong, and motorola may well have handled this better, this handsfree kit worked with:-
Hermes,
TYTN II
Touch Pro,
Sony Xperia,
Diamond2.
The kit within my headunit is built by parrot, so no small fish in the bluetooth pond.... It has a little menu with a list of models of phone with "funny" (non-standard) bluetooth implementations so that it can implement workarounds.
To top it off, others, with different handsfree kits have similar issues.
So, back to what I was saying...
I've just confirmed that it doesn't matter which end initiates the connection, if the phone was paired previously it skips, if you unpair and re-pair (during pairing the phone is connected as part of that process) for the duration of that connection the sound is flawless.
It must be using different connection parameters on that first connection, but I can't even see _any_ information about the connections, like bitrate/bitpool / sample rate etc.
Is there any way I can get the connection information for current bluetooth connections?
Does anyone know the way around the AOSP code enough to see if there could be any difference in the pairing connection to the normal connections?
I bet it really is that it uses "safe" values during the initial connection.

I have the same headphones and only notice skipping when I'm walking fast, with my phone in my pocket...or I turn my head away from the phone. But that's all my doing, not the phone.
I got my Nexus 7 last week and have not been able to put it down. Recently I got a bluetooth keyboard to go along with it and it brought some major bluetooth connectivity issues to my attention. Has anyone else had any issues with bluetooth accessories on the Nexus 7?
The problems I have been dealing with:
When connecting to a bluetooth device whatever screen I am on on my tablet refreshes (ie: home screen redrawn, chrome all tabs refresh)
Bluetooth connectivity drops momentarily (tethering or connected to bluetooth keyboard)
I'm trying to figure out if it's the unshielded speakers on my office desk or if it is an actual problem with the bluetooth module on my Nexus 7.
Quick update, I've been able to recreate the issue with the screen refreshing/redrawing when a paired device is connected and disconnected. It seems that anytime you connect or disconnect a bluetooth device it refreshes whatever screen you are on (if it's a browser window where you've filled in a bunch of text on a forum you will lose all of it because the browser tabs refresh as well).
While I have not tested this specific BT setup I can confirm that the BT performance on this device is horrible. Specifically with BT headsets when used with any VoIP app or even Google talk.
I hope it is just a software issue and will be fixed with an update.

Here's a quick video of what's going on with mine. I have another Nexus 7 arriving today so I can test to see if it's just an issue with the one I currently have.

I have been unable to play an .avi movie with a bluetooth headset, it freezes after a few seconds. It plays no problem without it. I have also had issues with the tablet becoming very slow when tethering to bluetooth, at least for number of seconds (> 30), presumably when it got internet and started syncing...but no slowdown on the wifi, so it wasn't the syncing with the issue, but the bluetooth part of the communication, I believe. Anyone else been able to play movies with a bluetooth headset or speakers?
I have had no trouble at all with Bluetooth. My Samsung Hs3000 works great with music,movies and any internet or sys sounds. It Also has a very good range of at least 75ft or more in the open and covers my downstairs when inside.
I have been able to pair 2 headsets. 1st had no function at all, ext. mic did not work and no sound- using groove ip or playing music. 2nd was a stereo bluetooth set with ext. mic. No transmission with groove ip. However, with this one I was able to listen to music.
Also paired with 2 phones. One with JB-( Gnex )and one (Note)with ICS. No data transmission to tablet with either one over bluetooth.
same issue - getting sound on voice
I've bluetooth paired with phone and media audio connected.
I get the sound but not mic.
This is with nexus 7 4.1.1 using novero rockaway headset...it works fine with the ipad.
any ideas? I'm stuck.
I recently got a new Nexus 6 and I'm having bluetooth connection issues specifically in my car. Bluetooth will connect but when it connects it shows "Bluetooth connected (no media)". So I can make phone calls over bluetooth in my car but my phone won't play media (waze/gps, local music, streaming music, etc). I have no problems connecting via bluetooth to a portable bluetooth speaker at home. Previously I had a Nexus 5 that I had no problems connecting to my car's bluetooth and making phone calls or playing media.
I've searched forums/google and have disassociated the pairing multiple times, ensured that 'Media audio' is checked in the bluetooth paired device settings, deleted the bluetooth cache, rebooted and nothing seems to resolve the (no media) issue.
It's strange because everything was fine with my old Nexus 5 and the Nexus 6 works fine with my separate portable bluetooth speaker but it won't play through my car's bluetooth. Has anyone experienced this?
Thanks!
Anyone?
Same issue

Sorry I don't have an answer, but you're not alone. I have exactly the same issue. Normally seems to solve itself when I manually turn BT off, then back on. But I hate to do that because it disconnects by Moto 360 and screws up a lot of other Tasker profiles that trigger from connecting to my car audio sytem. Sometimes I have to completely reboot the phone to make it work. I've tried a lot of things, but no luck yet. Hope someone knows the answer!
I had this problem one time before. Try bluetooth autoconnect. A2DP seems to not be running on your phone.
I'm having the same issue - brand new and it doesn't want to work on either of my phones I'm questioning the Integrity of the cheap $20 Walmart bluetooth car head unit
Is there a resolution for this problem? I've got the same issue as the op going on...
it can only be one of 3 things;
-your rom
-your kernel
-your vehicles bluetooth version
you can change/fix the first 2 things, but the third one is an expensive fix..
I'm running stock on the Nexus 6. It's not even rooted. Searching on this problem, there are posts that go back a few years. I figure with so many people running into this problem, someone must be working on a solution. I guess it's easier to just plug in the auxiliary cable?
I have the same issue . connected but no media. It worked properly after I re-booted the phone. We shouldn't have to do that so this bug needs fixing.
I have this problem with my new pioneer mvh-36bt deck. Only when I'm on a custom ROM though. I'd goto more options check all the boxes. Then clear Bluetooth memory on deck then it works. When I'm on stock rooted image no problems.
I had a similar issue when I switched from. Nexus 6 to 6P. In my case it turned out to be that there can be only 2 portable Bluetooth players that can be connected to my car multimedia. Deleting one of the 2 portable players and re pair Bluetooth resolved my issue
My Nexus 6 is the only Bluetooth device synced in the my car. I've tried deleting and re-pairing, turning the phone off and back on, turning Bluetooth off and back on, and nothing seems to work. :/

I have the same problem. My N6 never had any BT issues until I bought my new car today and tried to pair. My friend's iPhone worked just fine, so I'm pretty sure it's something in N6 that's the problem. Call function works but no media. This is very frustrating...

Curious if you've selected gear icon, in BT screen by device name, after paired AND while connected to view / enable all relevant options?
Sometimes when I pair I must manually update the BT access, though rarely. I presume manufacturer pairing settings (external device, not N6) don't default to all available options. Can't hurt to make sure media etc. is enabled. Good luck.

Yea, they are all checked, but it doesn't make any differences. BT also keeps losing connection. Thanks for the suggestion anyway.

Oddly enough, when I connected my phone to BT speaker today, no media or phone cnxn. Took my own advice and checked the BT settings. All were checked.
Unchecked then rechecked phone and media. Slight delay after uncheck before system let me reselect. Voila! Phone and media cnxn restored. BT was connected whole time.

Yes! My 1 week old Nexus 6P same issue. But all other bluetooth device pair xcellent, shows and plays media!
OK, I got mine to work on my 2011 Lexus by first pairing it as a phone then pairing it as a Bluetooth media player. Works great! Frustrating that I had to do it that way, but I'm happy I don't have to plug my N6 into the microphone jack anymore.
This thread might be dead but I found it when I searched for a solution and so will be others.
I got a Kenwood DDX5016BT in my car. When you connect a new device it will just work as a phone. To enable media you have to go settings and register it as a Bluetooth device. It right on top of the iPod settings. Hope this helps anyone or even me in a few months lol

Hello,
I just purchased and installed a Pioneer AVH-4100NEX. So far it's pretty slick. I'll be using it with my Galaxy S6.
I noticed that when I try to disable the Call Audio Bluetooth profile from the phone side, it re-enables itself... like I HAVE to use the NEX for call audio.
I would like to be able to turn on my BT headset and use that instead, without much hassle. There are definitely times where I'll be in the car with other people and don't want the whole car to hear the conversation. It also presents a call quality issue with the far end being able to hear the system speakers.
Do I have to unplug USB from the NEX to make this work?

I'm bumping this up. With my previous phone (LG V10) I could select which device use to make phone calls, Android Auto device or a bluetooth headset (Plantronics). Now with a Oneplus 3T that is not possible anymore.
AA automatically rerouting "BT phone" to main AA device. That is really annoying.
If someone knows a workaround to this please give advice, thanks...
You have to have it enabled, in a nutshell the unit (Pioneer) declares that it has bluetooth capabilities and declares the bluetooth mac address when it initialize the connection, than Android Auto (trough Google Play Services which is a system app) will enable the bluetooth, set up a pairing if it doesn't exist and connect to it, so no matter what you do it will always connect to it, the only way to "avoid" this is:
a) Get another phone which connects to the Pioneer bluetooth, then connect the phone (haven't tried this, but probably will do the trick)
b) Alter the pioneer unit so it doesn't send the bluetooth mac and it doesn't declare the bluetooth service (almost impossible, you will need to replace the app on the unit)
