Bluetooth AVRCP Being Ignored - Epic 4G General

I bought a bluetooth car kit to play music with. When I first paired the device to my phone, all 3 the media buttons worked (play/pause, forward, and back). The next time I used the kit only the play/pause button worked.
Knowing Samsung sucks at everything, I didn't waste my time disconnecting/reconnecting. I plugged the phone into the ADB interface and watched the system log in DDMS. What I found was really confusing.
I plugged the bluetooth kit into a 12v source and connected the 2 devices. I played some music off my phone and watched the log as I presses some buttons. In the log, the button presses were actually showing up in the log with the right scan numbers but the media player just doesn't respond to anything other than play/pause.
If I try different combinations of connecting/disconnecting I can get the media buttons to work but 90% of the time they wont. WTF is happening T_T

I have not had that trouble with my bluetooth head unit. I have been using Pandora and Mixzing. I only have issues with audio dropout and it seems to disappear (stop dropping) after the connection has been used for maybe 10-15 minutes.

It worked perfectly with my Samsung Omnia.

I found out that the bluetooth controls only work when the media app is in the foreground. If I'm on the home screen the controls will be ignored. If I have pandora open on the screen, pandora will be controlled.
This is annoying and I wonder why nobody else is having this problem.

I understand your frustration. And if I may, I would like to add this question:
Does anyone have a handle on the interrelationship between the Epic 4G, wireless headsets, and AVRCP music players?
My rooted Samsung Epic 4G is running 2.1 and has the stock ROM.
I’m looking for a compatible MP3/Wireless headset combination using either the Motorola S9-DH or S10-DH, or the Rocketfish RF-MAB2. So far, I am unable to do everything the headsets say I should be able to do, that is, answering a call and having the player resume (both headsets get this far) and also controlling the MP3 player, i.e., allowing for track skipping, pausing, etc.
In short, I do not have control over an MP3 player’s basic functions from a wireless headset.
I have tried both the Motorola and the Rocketfish. While the Motorola does not see an MP3 player at all, the Rocketfish does control an MP3 player’s volume level.
The following MP3 players were tried: stock Epic player, Winamp, PowerAMP and MortPlayer Audio.
I am open to suggestions. I am not wed to the Motorola or Rocketfish, but I am comfortable with the way they sound and fit.
OR...would you buy the headset you like, work the MP3 player manually (not a good idea while driving) and tough it out until Froyo addresses the issue of Bluetooth connectivity?
Thank you.

Wireless Stereo problem on 8125?

Hey, humans!
After searching through the forums for a couple of days, I thought I would go ahead and post to ask if anyone has a fix for the following problem...
I recently purchased the Jabra BT 620s stereo Bluetooth headphones, tapped the A2DP cabs, and got wireless stereo working (along with all of the buttons and the mic) right away.
Unfortunately, every time I turn off the headphones and reconnect them, they connect to the phone as "Hands-Free" only. In this state, I can use the answer/call/play/pause/etc. buttons and the mic, but audio is delivered through the 8125's speakers and not the headset. To fix it, I have to open the BT settings, click on the Jabra phones, Refresh (because it still says that the set is connected as "Hands-Free" and "Wireless Stereo"), and reactivate "Wireless Stereo" every time I want to listen to music.
Is there any trick/registry tweak that could help me bypass this extra step? Oh, and does anyone know of a media player that doesn't hog my resources like WMP, uses AVRCP, and can play streams?
Thanks in advance!
In response to my own (2nd) question...I've read that TCPMP respondes to AVRCP commands.
Does anyone know how to get them to work with the Jabra BT 620s headphones?
I'm continuing to look for a solution to my problem and find an alternative to WMP10, which sucks up so much memory.
I have finally managed to get Pocket Player 2.72 (http://www.conduits.com/products/player/download.asp) working with AVRCP. Although it is supposed to work right out of the box, I tried using it and received no feedback from the Jabra BT 620s's buttons.
While looking for a WMP today plugin -- one that I had hoped would have a smaller footprint while still allowing AVRCP controls to function -- I came across a post and eventually found a .dll for Pocket Player that allows me to use my Jabra's controls to influence the player.
Unfortunately, Pocket Player is a woefully bad player (even worse than WMP10 in my opinion!) and I can't get much use out of it because it “skips” constantly and forces the screen back on (it doesn't automatically shut off again) with every command from the headphones. However, for everyone who prefers PP and can't get Bluetooth to work through it, trying downloading this rar file (http://www.modaco.com/index.php?act=Attach&type=post&id=19163), unrar'ing it, and placing the enclosed .dll in your Pocket Player directory.
I personally really like pocket player, but you need to wait for v2.73 out soon apparently. If you go to conduits forum you can see alot of info on this issue.
I find it plays beautifully thru iTech Clip R35 (I admit I have a different device ie jamin).
But to your first point, I still have that problem as well, I have to manually switch on the bluetooth stereo option, I haven't found a solution for that yet.
cheers

Hi, I just bought the BT-620s and have exactly the same problem you have mentioned, otherwise a great BT headset.
Did you ever manage to find a fix for this problem?

Bluetooth Stereo Headset w/Phone - Stop Music Restart - Help!

I have a x7500 and using Bluetooth Receiver setup with headphones and headset for phone. Good news is that all of this actually works pretty well overall. Bad news is that my MP3 music players restart automatically after I receive a phone call upon the ending of the phone call I can tell Pocket Player not to restart after the phone call and this works. However, iPlay still wants to start no matter what! Is there any way to tell the audio gateway or A2DP or ???.....NOT to restart music after a phone call ends.
I would appreciate any help on this. I have been searching forums and looking at registry entries but no success in stopping the restarting of music players so far.
that is a software compatibility issue
i have no problem listinging or watching movies via AD2P
when phone comes in, it pauses, and goes to Phone mode
when i finish talking, and hang up
it switches back to Music / Movie mode in AD2P
no restart no issues at all
using CorePlayer
i got 3 different headsets
Jabra BT8010
Moto HT820
Sony DS970
they all work perfectly
my guess is the Pocket Player you are using?
try another Audio Player software
Yes. I agree. It is a compatability issue but sometimes there are still options to exert control. So Pocket Player has option to restart after phone call but iPlay does not. Thus Pocket Player offers pretty good control in this area. However, it just so happens that iPlay has some very, very high end features that I really like but just does not have the phone handling at this time with the version that I have (although plays fine thru Bluetooth). I am hoping there might be some registry setting to tell A2DP not to try to restart music after a phone call.
Anyone ever heard of the ability to do this?
doesn't have to be a software issue. I have the same problem but with Touch Flo 3D skin. It starts playing music after the call, even if before the call I wasn't listening to the music I've tried to disable the Touch Flo 3D, but then the standard Media Player starts after the call . I have to remember to turn off the music after every call - it's driving me crazy!!

Bluetooth weirdness

Got the mini last week and am generally loving it
However, a couple of niggles. When I'm driving to work I have the mini playing music via a bluetooth audio device (that transmits FM to the car radio) and when I get to work I listen to same audio through a JayBird stereo bluetooth headset.
My previous two phones (both htc and windows mobiles) have coped admirably with this. However, with the mini, when I get to work, connect the JayBird and then start playing music the audio profile disconnects. I then have to keep reconnecting and eventually it seems to work but is a bit laborious. There doesn't seem to be a repeatable process to guarantee it working.
Not sure if it is possible to revert to the standard Windows Mobile bluetooth management - like I said things seemed to work with previous phones/custom roms etc.
The other thing is that the htc audio manager's shuffle doesn't seem quite so random as media player's! If I've got multiple songs with the same title it tends to play them all together... weird!

Problem with bluetooth/Music

Hi
First i have to say is SORRY about my english. I'm learning and i don't want to use a translator.
I have a Nexus One connected to my handsfree on my car. I have a Ford Focus. Well when i try to listen some music on it, stock music player star to play and stop, start and stop anbd i don't know why.
I have flashed many times OxygenN1 mod and for all other things the rom is perfect but i don't know why do this.
I have to say to, if i try to play music with another app it starts to play normaly while stock player is playing on the buttom so this is imposible to listen anything.
Thanks for all.
Anyone can help me?
Thanks
All I can contribute is that I am having the same problem.
I am using a Bluetooth headset to listen to podcasts - this is one of those headsets that supports the A2DP profile for playing music etc., as well as the normal headset profile for phone calls. I don't have the problem when taking calls, just when listening to music/podasts so I suspect a problem with the A2DP profile implementation.
You are probably using that same profile in your car.
I wasn't sure if it was the phone or the headset that had the issue - sounds like it is probably the phone if you are having the same issue.
For the record, i have the AT&T/Rogers Canada version of the N1, with 2.3.6.
A couple things to begin troubleshooting:
1. Try using your phone with a different vehicle. It would be helpful to try pairing your phone with a different car's Bluetooth stereo, and see if it works properly (maybe a friend with a recent car?). If that works, then the problem is with the car stereo.
2. If you have a friends with other smartphones, try having them pair with and play music through your car stereo. Hopefully a pattern would emerge: maybe your exact ROM doesn't work, maybe it's a hardware quirk in your phone itself.
3. What media players do you have installed? I occasionally have conflicts between players fighting over the Bluetooth connection; Pandora and the stock player used to fight, but now they play nice. Notably Pandora has a section in its settings that tells it whether or not to take over Bluetooth controls. This sounds like it might be the reason for your second problem (if I understand you correctly).
4. You might also want to try a different firmware, maybe one that's either closer to stock or further. Maybe try the stock firmware first, then maybe MIUI.
5. What year and model is your Focus? Sometimes (rarely) there's a firmware update for the car stereo.
If the stock player is starting and stopping by itself: first try uninstalling all other media players and see if it still happens. If it does, it might be that the car stereo is sending pause keypresses, which it shouldn't. There might be a defective button on the stereo, or maybe a quirk in the stereo firmware.
Hopefully some of this helps narrow down the problem. Let us know if you get any results, hopefully we can help find the problem!

Are you using the headset for both podcasts/music and taking calls? Or using the headset for part of it, and another Bluetooth device for the other?
I just ask because I once tried leaving my voice-only earpiece for handsfree talking while listening to music over the car stereo. I had them "working" configuration-wise (the earpiece took only calls, music went only to the stereo), but after a little bit the phone would sort of melt down and lock up. It was probably running turn-by-turn Nav at the same time that did it, still it was cool while it worked
There are certainly bugs in the A2DP and AVRCP profiles, but I understand the implementation is kind of complex and there's a lot of corner case problems. Personally, our stereo displays the artist & album names, but always says "Paused", and the title and time info and just random numbers.
About the best you can do is try to isolate your specific problem, then try to find where to file a bug report. CM is probably the most responsive but most resource-strapped for fixing corner case problems, Google is at the other extreme and never really replies to bug reports. The stack itself is written by the BlueZ group (which I can't link, you'll have to Google); I've never tried submitting a bug report there, as I suspect they wouldn't be interested in hearing from a 3rd-party Android ROM user.
This might sounds odd, but try turning wifi off and see if that solves the problem.

try downloading ES Explorer (this has a player built in) browse to the audio files and select play in ES media/audio, I could get music to play through this but not the stock player because it would keep stoppping after a second or two.

Bluetooth problem

I listen to stuff on my Galaxy Note via samsung bh 3000 Bluetooth headphones. My problem is that occasionally the sound just stops. It's not that the Bluetooth connection has been broken - the device remains connected, and I can still stop and start the playback by pressing the button on the headphones. When I do that stop and start, the sound comes back again if some budy call me.have flashed all diffrent kernels with some kernels it works some time. Any ideas of how to avoid this problem?

I have that problem too. I've only had my BT headphones a couple of weeks (Plantronics Backbeat 903+). I use Power Amp.
The BT connection is still active. Other sounds come through OK. The play button on Power Amp shows the pause symbol though, as if it is still playing. I usually have to force close PowerAmp and start it again to get the play button to work again and to be able to hear music.
Yesterday I tried using the stock music player when I went for a bike ride and it didn't stop at all. So I don't think it's a problem with the headphones or BT on the Note.
I don't like the stock player much (sound and interface) though, so I just downloaded the player pro demo and will see if that plays nice with my headphones.
I never noticed the problem when not using the BT headphones in PowerAmp, but I've never used it for a long period without the BT headphones.
I'm on the stock LC2 with root.
I'm using Nokia bt905i headphones as well as a parrot bt interface for my car stereo, and these for several hours a day. GN side, I use poweramp player and a series of Internet radio players.
Never had a problem of this type.
Kernel : cf-LC1, stock rom.

I did some more testing today.
I had the same problem using Player Pro, but again, no problems with the stock player.
What I did notice, that it seems to coincide with announcements I get through Sports Tracker.
So if Sports Tracker gives me an update on distance or tells me it has auto paused or auto resumed timing, then sometimes (not all of the time) Player Pro and Power Amp seem to freeze up and the play button is stuck on pause.
I have to stop the app via task manager to get it to work again.
The stock player doesn't seem to have any problems.
I'm not sure why, or if this is just a coincidence, and if it is just with BT (I only use Sports Tracker when I use my TT headphones too).
Maybe when Sports Tracker access the BT audio, it's conflicting with the way Player Pro and Power Amp access the audio, but the stock player doesn't have a problem?
But it's not all of the time either, sometimes I get the Sports Tracker updates and Power Amp and Player Pro keep playing fine...
Do you have anything else trying to access your BT audio at the same time too ?
If you are talking about Sports Tracker of Sports Tracking Technologies (there are many of them called "Sports Tracker"), from my experience I can say that this program causes a lot of problems in wireless communications of my Galaxy Note. For instance, it interacts badly with phone's wifi radio, so each time I use it, I first turn wifi off and, what's more, when I finish using it, I go through the application manager to Force Close Sports Tracker. Otherwise, sooner or later, I'll have to restart my phone! Notice, that while activated, Sports Tracker works fine with my polar bluetooth heart-rate belt (no disconnections).
Yes it is Sports Tracker of Sports Tracking Technologies. I haven't noticed any problems with wifi on my Note. I use wifi at home and it has worked each time I've come home.
It works fine with my bluetooth headphones in terms of giving status updates. But I'm starting to think those status updates cause Power Amp and Player Pro to freeze.
I might try Endomondo tomorrow and see if that makes any difference to Power Amp and Player Pro...
Therese a app called btswitch from market. It helps.the problem is you must switch it on every time

Just an update on this, I emailed the developer of Power Amp the other day describing the problem.
He sent me an updated apk.
I've used it for a 40 minute and a 60 minute session with Sports Tracker and my BT headphones and no music freezing. So he seems to have fixed the problem I was having.
I'm not sure if you were using Power Amp also, or some other music player. But if you are, it might be a good idea to contact the developer, or wait for an update if he integrates the changes into the next release.
Volume Boost app
What you're describing will happen if you have an app called Volume Boost on your Note. As the name implies it helps to boost the sound volume and bass a bit for your headphones. But I find interferes with Bluetooth and the built in FM radio when its activated.
If you have the Volume Boost app, set it that it does NOT come on at start-up and DON'T put it's widget on the home screen. Only activate it when you need it.
