Hey guys, new to the skyrocket, not to android. I noticed with my captivate, and now with my skyrocket, that when I stream higher pitch music via bluetooth to the microsoft sync in my truck, I get some white noise in there... After extensive googling, I have found that it has to do with the bitpool that the manufacturer sets (kind of like bandwidth for bluetooth). Does anyone know of any roms that do not have default bluetooth settings? In particular, bitpool settings. I know CM7 does that, but I read that it is pretty buggy and I need something as a daily driver. Any help???
I would like to confirm that this is happening with my skyrocket as well. Would like to know if this could fixed in some kind of skyrocket ROM.

I go bike riding (pushbike, not motorbike) with groups of people sometimes, and we've been listening to music using the built in speaker of my BlueAngel. Of couse the volume isn't great especially once it's safely back in it's holster.
So while we were out the other day, we started thinking of solutions.... We started wondering if bluetooth could be useful to us.
Can we play music out to ordinary bluetooth headsets?
Can we send to multiple headsets at once?
Extending onto the idea, is it possible to use bluetooth headsets as intercom type things (using some software on the BA maybe)?
I don't have any bluetooth devices beyond the BA, so I can't test
In case it matters, Im currently running 2005 on my device. I am considering going back to 2003SE though... Is there anything I would need to know in that department?
No one knows?
Anyone with access to multiple bluetooth headsets or sets of bluetooth headphones able to see if you can do it?
try doing a search for a2dp
most of what you are asking have been
up 1024 times before
doubt you would find info about anything but the first q though
the others i dont think is possible
also bluetooth headset range seem to crash and burn after 2-3m
personaly i use these

they work for me
I'm looking at buying a new car and I tried playing music through a couple 2010 Toyota non-navigation radios. All the Android music/video players I tried would sound great for the first few seconds and then start a subtle warble/echo that continues until you pause/resume or switch tracks.
I've got an ADP1 currently running Cyanogen 4.2.11.1, but I saw the same problem with 4.2.9 and 1.6 (don't know about all the other various builds). I have several A2DP headsets and they always work fine (no warble).
I believe this Toyota radio is running Symbian OS from what I found on the web; and I'm going to try to see if Toyota has a software upgrade tomorrow. (I doubt it) Toyota does mention that most Bluetooth features are supported for the MyTouch, but doesn't mention A2DP either way. http://toyota.letstalk.com/brands/toyota-bt/home.htm
I'm downloading the whole Cyanogen tree and preparing to build it and then sniff through the code for buffer sizes and other likely suspects.
I just thought I'd pop this on XDA and see if anyone else has seen the same problem and found a solution.
Or does anyone know specifically where to look in the source to adjust buffer sizes and other things that might cause a warble with Bluetooth audio.
You should test before getting the car, ask the dealer if you can test the BT with the car when you get there.
I have been running A2DP on my Sony headunit for some time now. I have never experienced a warble on any of the roms I have used. I do get another issue however and maybe they are related. I can not stream stereo audio over BT to any device it seems, IF I also have my phones wifi enabled. As stated I do not get a warble, I get an audio drop for a few seconds every 30secs or so. This does not seem to happen if the headset is the only part connect, as soon as I connect the A2DP portions it starts up. Disabling wifi is my work around at present.
I have tried A2DP with/without WIFI enabled. No difference; still warbles.
Nothing interesting shows up in logcat.
I run A2DP through my ford focus with the microsoft sync system with no issues. Although the AVCRP does have issues. The control won't work after the phone goes to sleep.
The warble or echo may be due to an active system used to reduce road noise when using the phone hands free via bluetooth. Might check and see if there is a way of turning that off. Some of the foreign cars have active mics placed in the car that might cause this.
try an eclair rom (like manup456's 1.3)
BLUETOOTH IS IMPECCABLE ON THESE ROMS
it will work.
I tried turning off/on the auto volume; no help.
I'm not sure how to check/disable any bluetooth feedback; but it doesn't sound like that.
My friends Blackberry either worked fine (no warble) or was very very jerky (played quarter second, cut out a half second). And split its time about 50/50 between these modes.
I should mention the "warble" is not very pronounced, I can listen to most music without it making me crazy; but it bugs me.
Finally got all the stuff from git; now compiling the kernel.
I will try the compiled kernel tonight and if no luck there I may try the eclair rom mentioned; but I thought Steve's build already had most of the eclair stuff; maybe he is waiting on his experimental branch.
Edit:
oops, looks like a2dp stuff is not in the kernel....
I run A2DP on my kenwood deck. The only issue I experience is if I turn off the car and kill the stereo before killing my BT on my phone, my phone goes into freak out mode. I can't enable or disable BT untill I give a 3 finger salute and it just runs really slow. No warble, actually from CM 4.2.11.1 it sounds pretty damn decent.
I'm still trying to figure out how to compile the code from git; got the kernel and main tree compiled; but not the external apps (like a2dp).
Toyota gave me phone #s for Panasonic and somebody else who make the head units. So I am still pursuing a software update from that end as well. I'll call them next week after the holidays.
I've read thru the liba2dp.c code and have a couple ideas to try if I can figure out how to compile it (haven't really tried that hard, just looking for the official directions so I don't waste hours on something that is already known)
dude your doing too much work just try the eclair rom!!
I am experiencing poor sound quality while streaming audio over bluetooth from my Captivate (Apex 9.2 w/Talon .22) to my new car. Is anyone else experiencing crackles during treble intense moments while bluetooth streaming? Is there a setting I am missing? Is this a kernel, rom, or captivate hardware problem? Is there a way to get to the bluetooth bitpool settings to change bitrate (supposedly CM7 has it set to 53 and sounds good)? Before I go crazy and flash the captivate bootloaders and switch to an official 2.3.4 rom (from an I9000) I wanted to get some opinions. Thanks for the help!
**EDIT** - Am I the only one experiencing the audio crackle issue?
gte460z,
This is an issue with most if not all Android OEM's trying to use their own propriety bluetooth drivers. The poor sound quality you are experiencing is coming from a low bitpool setting that is unchangeable using any stock based ROM/kernel. The only way I have found to get around this is to flash CM or any AOSP ROM. CM is what I use since I also use bluetooth A2DP to listen to music in my car. It makes a huge difference! I hope that was the answer you were looking for.
I am in the process of installing CM7 now. Just flashing the stock kh1 bootloaders then I am off to recovery for a nandroid backup ending with CM7 nightly 104 flash. I will report back with my findings but it sounds like this should work.
CM7 did not fix the crackles/static. Any other ideas?
**EDIT** When I check the pairing in the bluetooth settings with a long press on the device name it comes up with a check mark next to set of headphones and a check mark next to a phone meaning it is connected to stream music and phone audio. I wonder if the check mark next to the phone is setting the bitrate to the level needed for a phone call instead of music. I will test tomorrow and report back.
I have some more ideas but don't have time right now. I'll get back to you in the morning.

Alright, thats strange that CM didn't fix the problem. Something tells me the problem lies elsewhere. I have a few questions for you....
1. Do you have another phone/device that is capable of doing A2DP?
2. What is the source of your music? (Pandora, local, etc...)
3. If local what is the bitrate?
4. Does you car have an AUX jack where you could play the same media to it through that to test the quality?
Hi all,
I am having an issue with my Skyrocket streaming bluetooth to my toyota prius and am wondering if anyone has experienced anything similar (I have been searching the forums with no success).
When I was on Gingerbread, the bluetooth audio streaming to my Toyota Prius was working fine. I recently upgraded to the leaked ICS builds and for the first week it seemed to be ok but I am now experiencing (for lack of a better way to describe it) intermitent bluetooth audio. About 90% of the time when I play music in my car it sounds like there are long pauses/drop outs (If I continually do pause/play it sometimes works). The really strange thing is that it initially worked fine and even now if I try my motorola headset it works perfectly. I was wondering if anyone else has experienced this and if there are any suggestions on how to fix it? I have tried multiple versions of the ICS ROMS and the issue seems to be persistant across all of them.
Skyrocket currently running the NexusMod rom (having tried many more) and have tried to clear the cache (both of them), fix the permissions, and superwipe/reinstall the various roms.
Thanks,
Dave
Hey guys Im currently having a problem with my phone. I just installed a JVC Bluetooth stereo and I only get this minor static through my speakers when on bluetooth. Its not bad and plays under the music but It would drive me crazy on long trips. It plays great though my dad's stock android phone on blue tooth. Playing cd's it doesnt give the static. So it has to be something with my gs3.
I currently have root66_VZW_I535VRBMB1.7z which is 4.1.2. My kernel is 3.0.31-861013. build number jzO54k.i535VRBMB1 installed on it.
Does anyone have any suggestions on what I could try to fix it. Another rom maybe?
Thanks,
Makos
