BT Stack issues... - EVO 4G Android Development

Ok so started with nexus one, now with the EVO. I'm thinking its just Android.
Ive got a Pioneer 7100BT in the car. But research shows this to be a widespread issue.
I can pair and all the audio goes through properly. Pandora streams through the car. I can access my phone book, make and receive a call. The only problem is the call audio is always rerouted through the phone....
Any ideas?

Fuze - connect A2DP to car stereo for music, and HFP to Jawbone at same time?

Hi,
I searched the forum, wiki, etc., but didn't find an answer.
I have an AT&T Fuze with the stock ROM (WM 6.1). I know the Fuze is supposed to support multiple simultaneous bt connections. What I would like to do is connect A2DP to my Pioneer stereo for music playback, and also connect handsfree to my Jawbone 2 headset for phone calls while in the car.
I can successfully connect A2DP to my stereo for music by itself.
I can successfully connect HFP to my Jawbone 2 by itself.
I *have* managed to connect to both at the same time, by staying on an active phone call with my Jawbone, then telling my Fuze to connect to the car stereo. However, no music could be heard (from either Mortplayer or WMP). The phone call stayed up just fine though.
Anyone know if there's a way to get both working at the same time?
(And before you ask, I would just use the hands-free capability of my Pioneer stereo for phone calls too, but I've found my car is too noisy for anyone to hear me with the Pioneer's microphone unless I hold it right in front of my mouth, which defeats the "hands free" goal...)
Thanks for any help you can offer.
Best,
Chris
In your case I do not think that is possible since the concept of being able to juggle 2 devices at the same time requires 1 to relinquish control while the other goes active. It turns off the music so you do not get distracted while talking and reconects the music after the call is over.
It seems to be a software protocol if anything. Yes both can be connected at the same time, but both cannot be "active" as in doing both music playback and voice calls.
I have a bt headset that handles 2 profiles at once and according to the protocol, if a call comes in, it pauses my ipod and then picks up the call and then resets back to normal after the call.. Either you have to mess with the coding itself or someone has to come up with a workaround, but I do not think that is possible.
Thanks for the reply. I had hoped it might be possible for the Fuze to route stereo audio to one BT profile (A2DP), while non-stereo audio (e.g., phone call, system tones, etc.) to the HFP profile, almost as though the profiles acted as addressable "service ports" (ala HTTP, SMTP, etc.).
But, unlike with TCP/IP, I admit to knowing next to nothing about how the BT stack works and how profiles are applied to certain types of data (or, how data is routed to a given BT association based on profile).
Thanks again,
Chris
well the thing is.. the fuze can connect to multiple devices simultaneously, but based on the music and voice call order, it is prohibited from doing both at the same time. so therefore when there is no call, the music plays, but when a call comes it, the music is paused and resumed after the call is done. (obviously the call has higher priority here).
My only suggestion is to leave it as it is since it is done so that you do not get distracted while talking and probably while you're driving.
Multitasking is difficult when you're listening to 2 things, responding to 1, and driving at the same time. The more you multitask the less you are able to devote to your main activity (in your case, driving).
but yeah. if you can find someone who can mess with that and allow for both to be active at the same time, then congrats. Otherwise just think of it as a safety measure.
Except that, when I had both the headset and the stereo connected to the Fuze, the music *didn't* pause. It just didn't output (as though the volume was muted). In fact, in both Mortplayer and WMP, it appeared as though it was playing at ~2X the normal rate (just watching the track playback time counter).
I know what you're talking about re: listen to music, call comes in, music pauses, call ends, music resumes. That's the behavior I get when I use the car stereo for both handsfree and A2DP.
The behavior when connected to two different devices seemed to be different, though, so I hoped that might mean it was in fact possible.

yeah I know what you mean, but maybe the fact that it tried to do both tripped it up and so it took the call as a higher priority and focused the data towards the call.
atleast that is what I think.
I have almost the exact same configuration, except I am using a Sony car stereo but have a jawbone. What I have to do every time I get in the car is the following.
1. Let my stereo connect to both hands free and wireless headphone services.
2. Open bluetooth settings
3. Manually connect to my Jawbone.
It works great.
ATT Fuze
Energy Rom 072209
Old jawbone
Sony XPLOD Car Stereo
I'll also add it's pretty neat to be able to push the jawbone to activate MS Voice Commander and choose what music I want to play over my car stereo.

Thanks for the reply. I'll give that a shot. I'm not sure that my Pioneer stereo will automatically connect both handsfree and A2DP. I know it will do handsfree automatically. We'll see...

Bluetooth Fix

Is there anyway to fix the Bluetooth streaming? I hoped maybe another audio app would be more streamlined than the one that comes preloaded with the phone, but they don't allow me to stream music through bluetooth. Right now my phone sucks at streaming music, even when I close every other app open. My last phone never had any problems at all with A2DP, but I can't get this one to play music at the same level which is a major buzz kill. If no fixes are known, is it reasonable to think that this situation might be alleviated with the Froyo update?
I'm having the same problem, and it's a deal breaker for me. I need the bluetooth A2DP to work. This same headset worked on my Fuze for over a year. When I use the headset on the Captivate, the sound starts and after a minute it fades out to nothing. I've tried Dogg Catcher and the default player.
I dont know...I got a blueant Q1 when I bought the phone and I've no issues using mortplayer, default video player, pandora and radiotime over it.
I did have one problem, when i first connected it, my bluetooth was connected as a single bluetooth. I disconnected and unpaired, then repaired and instead of the phone icon next to my bluetooth device in settings I now have a headset icon. So any sound whatsoever that comes over the phone from 'tap' sounds to games to music comes over my blueant....
Main thing I had to do was unpair and repair to make sure I had headphones icon next to my bluetooth device in Settings-wireless and network-bluetooth settings
I am hoping we can get better sound quality with Froyo. My Old Tilt sounded better than this.
I figured it out. My headset is a Jabra 8010. Factory default on the headset fixed it. First I unpaired it from the phone, just for good measure. Turned off the media player, turned off the bluetooth signal and headset. Turned the headset, defaulted it, then turned on the phone's bluetooth, then the player. Not sure if all that was needed but, it's working.
And the sound is much 'richer' than when it was paired with my Fuze.

[Q] Redirect (nav) audio to buetooth

Hi there,
I want to have my GNote to send all audio over bluetooth to my car (new Alfa Giulietta) which has the Fiat Blue&Me system.
The phone and car are connected and I can do phonecalls within the car, so this
setup works.
I've found a programm called BTMono which should work, but not with my setup.
If I switchon BTMono, the phone becomes quiet ut there i no sound from the car stereo.
Somebody else has done it with blue&me, and he gets a unknown phone call
in his car-screen when he redirects the audio (hesh.am/2012/04/stream-audio-from-an-android-phone-to-a-fiat-equipped-with-blue-me-via-bluetooth/)
I think the car must think that it's an actual phonecall, so the phone must send the proper commandos to the car.
Does anyone have any suggestion on this?
same here
It happens the same thing here. GM Cruze LTZ. Wouldn't it be that BT on it wouldn't be able to stream audio, just phone calls?
Normally it would
Normally it would, but with apps like BTMono it should be possible to stream audio to a bluetooth headset or carkit like the Parrot.
So I thought that blue&me could work for me also, but it doesn't

[Q] Audio at phone even though Bluetooth headset

I have a Plantronics Voyager Legend Bluetooth headset which I use with the Nexus 5.
(Almost) every time I make a call, the headset first blips and you can see in the dialer that Bluetooth is chosen for sound output.
But just after dialing, the audio is back at the phone (handset earpiece). So I have to switch to Bluetooth again. Then during calls, sometimes the audio is routed back to the phone again.
It always works when you move it back to the Bluetooth headset again but it is very annoying.
Phone has stock 4.4.2-latest.
Any other threads about this? Bugs @ Google? Couldn't find anything..
I guess it depends on the Bluetooth device you're using. My nokia bluetooth headphones work perfectly where as I face similar problems like you when I'm using it in my car.
Maybe try the app soundabout from the playstore. Seem to work (sometimes) on my N4 when I had phone audio problems.
Easy solution to my problem: Unpaired the headset and paired it again, now it works as expected!

Bluetooth Audio

How is the Bluetooth audio quality on the S6? I use many wireless headphones and speakers so this is an important factor for me. Is it true that the Bluetooth audio randomly stops sometimes?
Mine randomly starts to skip and pop after some time playing. Turning the BT off/on fixes it for a while.
The problem is worse when paired with my Bēm speaker, rare when paired with my JBL speaker, and nonexistent when paired with my Sony soundbar.
All of these speakers work fine with my other devices.
I only use bluetooth with my truck's stock stereo, but this is the first Android device I've had paired with it that doesn't skip over BT. I've used it with S6, Note 3, Note 4, S5 Active, S4 Active and iPhone 6+. iP6+ was the only other one that didn't skip.
S5 Active and Note 3 also skip with a Jensen BT Nav headunit in a different vehicle.
An update to my previous comment..
I went for an hour-long drive and experienced no skipping or popping while paired to my car's stereo.
It seems the issues are only with specific Bluetooth receivers/speakers.
I can get on-board with this. I have a few different bluetooth devices, all of which have no trouble, ever, but then sometimes (and ONLY sometimes) my BT headphones will skip and stutter to the point that I just turn them off. The other devices work fine 100% of the time.
I'm at my wit's end with the bluetooth on this device. It skips and stutters more times than not. It's embarrassing when friends are over and we're trying to have some background music playing.

No BT problems here. Maybe you have a defective phone. Take it back to the store and try to exchange it. There is no excuse for crappy BT on a $700+ device.
My wife has an S6 also, with the same issues.
I have FINALLY noticed an issue with the BT on my phone. When connected to my truck and listening to music, I go to a call (incoming or outgoing doesn't matter), when the call ends and goes back to the music, the volume "flutters". It goes low/high/low/high alternating twice a second. It's a very slight change, but it's enough to notice that it sounds "weird".
Exiting and restarting PowerAMP, or switching to a different input then back to the BT audio stream will fix it, so I haven't figured out if it's the phone or my truck.
