I found out that certain combinations of ROMS and Kernels work better with my CAR Bluetooth then other combinations. For instance CM6 is not working perfect and is uncertain to reconnect to my Car system. On the other hand most Sense ROMS work better with my Car system.
So in this project I wanna track down first which components have influence on the bluetooth stack, and more important which specific parts of the kernel, software and other things are related.
This to improve the BT Car system of at least my Scenic but I have the feeling more Car systems have issues.
Please if you have info about this put it in this treath so we can make it better.
Nice initiative. My BT system in my car works flawlessly with WinMo, but as soon as I connect my nexus, my speakers begin shrieking like all hell breaks loose. Also, My Nexus the seems to lock up and I need to pull the battery for all misery to end.
LOL.
That was the first time I connected the bugger, so I wasprobably still running Eclair when I tried it.
6.1.1 works well for me, both bluetooth calling and a2dp.
Theres a little fuzziness going on when nothing is playing, like white noise, but that's pretty much my only problem. No wait, there is one more thing actually, every now and then while music is playing it'll skip more or less a second
Just to add... I have to repair and disable/enable by every time I get in the car or the sound will drop out every 15-30s on any rom that uses froyo. GB seems to help where I only need to disable / enable bt. Kenwood x-993 with parrot bt. Using latest bt firmware.

This happens to me too once every three or four songs, but it's such a small thing it doesn't bother me much. On the other hand, for the short while I was using MIUI, I felt it was happening much less, but I may have been imagining that
Heres my setup, and it works flawlessly every time i start the car.
Car Deck: JVC KD-R900 (Using the small bluetooth adapter that came with the unit mounted in the back USB port)
ROM: Enomthers TheOfficial Nexus1 v2.14.3
Kernel: 2.6.32.35-TheOfficial-AudioMOD-720p
Radio: 32.41.00.32U_5.08.00.04
OS Version: 2.2.1
Like i said earlier i have no problems with the audio quality or connecting to my unit. As soon as i turn my Bluetooth on it connects within about a minute.
Calling quality is good, audio quality is good and AVRCP works also (play/pause/next/prev)
If you need anymore info just let me know.
Its good to see there is some reaction on the start of this.....
My goal is to achieve and to find out which components are involved in the Bluetooth experience:
F.I. :
* Kernel modules and libs
* Application in the rom to actually making the connection
* Bluez configuration and settings
I have done some searching but found that even with the same Bluez settings there can be a difference between some roms in combination with kernel.

Same here on my DDX-812. Almost everything "works", I just get the drop-out when streaming music if it's not a fresh pairing.
The bluez stack was updated with Gingerbread...I'm hoping against hope that that fixes some things.
i have to use a no-audio-boost kernel with my jabra headset, otherwise the call quality is abysmal. lots of metallic clicking and other strange effects going on.
but i have seen no differences in the overall connection stability otherwise.
hmm i have a problem with my car dock and bluetooth i think. when using the navigation the voice plays via the phones speaker not the dock speaker. is this similar to the problem in the 1st post? if so, would love a fix!
I'm on CyanogenMod Nightlies with the included Kernel and have a Kenwood DDX8024BT with built in bluetooth. It connects up perfectly when I turn the ignition on and seems fine when in call. I don't use the A2DP much but when I have I've not had any problems.
Slightly OT, the only problem I have is with reading contacts from the phone. I have two phones paired. I usually have the Nexus connected but occasionally switch to my work phone (a Tocco Lite). At some point it took the contacts from my work phone and then wouldn't redownload the Nexus contacts when it was reconnected. It's now done it at some point but there's a handful of contacts that still won't transfer no matter what I try.
On a side note, I have a Clarion CZ500 rig in my car, and the N1 is incompatible with the microphone boost firmwares they offer on their site. All I hear is crackling when I try to make or receive a call.
What's odd is that the HTC Desire works fine with those firmware. Even Blackberry Pearl.
I ordered the N1 dock on eBay. I guess I'll see if the dock can handle the firmware.
i have a n1 and im still running cm 5.0.8 with android 2.1
my phone pairs with my car without any problems and i am able to talk to people and whatnot. Now as far as music, i use a blackberry music gateway bluetooth device that i plug into my car's 3.5mm jack and then i pair that device with my phones bluetooth. It pretty much connects automatically all the time and sound quality is awsome however as someone mentioned earlier in this thread, i get the occasional 1 second skip every so often. Does anyone have any idea whats causing this and how can i fix it? It is extremely annoying!!! I paired the blackberry gateway device with my gf's mytouch and there was no such problem, which leads me to believe that the problem is in my n1 :/
My $02: I cannot use a2dp and hands free at the same time. If both are connected the the a2dp drops out all the time.
This is not an issue with my HD7.
A workaround would be awesome.

I suspect the main difference, hardware combinations aside, between Stock/CM and Sense roms is that they use different bluetooth stacks.
Differences in the bluetooth stack that have caused issue for the FM radio on stock roms, an issues for bluetooth file transfer on Sense roms as far as I know.
Like iphone fanboys would say: fragmentation
On a related note the behavior of my N1 with the Parrot handsfree has vastly improved in GB.
i have the kensington liquidaux bt adapter in the car and cm7 rc4 with stock kernel skipped constantly. rc2 was better, but still unbearable.
i am currently on intersectraven's 4/3/2011 kernel and from limited use, has not skipped on me yet.
have people tried bt music streaming with other kernels with cm7 rc4? wildmonk? pershoot? etc.. thanks.

i think thats exactly what my problem is, when the phone is connected to the car and the music gateway is connected as well i get the intermittent connection and it skips every so often but if i disconnect the phone part then the music never skips...however im not on CM7 so i dont know if that fix applies to me and i dont know how to begin changing those settings
My droid would use whatever BT headset (stereo or not) for the phone when my headphone jack was also in use (to use car stereo) for audiobook player.
I have new Fascinate and I swear it did the same until I rooted it. Regardless, it will be close to a deal breaker if I cannot find a solution to this.
Even if the headset indicator is ON, the sound still goes to the headphone jack, RIDICULOUS
In my opinion, plugging into headphone jack should only take over media type output (music, audiobook player, video) and LEAVE PHONE ON BLUETOOTH. We should at least be able to chose this behavior in a setting.
So is this a Samsung screwup? do other Samsung devices behave this.
How hard would it be for a dev to build an app to FIX this on Fascinate.
I thought I was the only one with that situation... I would love to know the answer/fix, however I have a feeling someone will be by soon to move this to the general forum...
I actually wanted the opposite. Overall, I liked how bluetooth was handled on my old chocolate and was surprised by the differences in eclair. I expected my bluetooth to be able to grab all audio, regardless of what apps were running. For instance I wanted to use my BT with a fring call. Seemed sensible!
Anyway, I went searching, and the prevailing opinion was that bluetooth was locked up until Froyo (and tightly tied to actual calls).
Does anyone know if audio is handled in a gracefully way in current AOSP or CM?

I believe that my Droid 1 behaved my desired way on 2.1 and 2.2, can't remember if I used this way on 2.0...
I was assuming this was a 'problem' on Fascinate or Samsung, not android OS in general.
I thinj its a problem with fascinate. I was driving for 5 hours last week and I had bluetooth connected to my garmin and used one of those cassette thingies to play music from my fascinate. Sometimes I were able to talk without unplugging the headset.
Another reason I suspect its fascinate is cuz when I use my old blackberry headphones I have unplug and replug to use it for conversations.
Btw whats good stereo heaphones with mic that works with the fascinate?

I have a friend with a Vibrant and his apparently does NOT have this problem, so I am wondering if a Bluetooth file from his system might work on my phone.
There are 3 BT files in system dump:
BT OPP
BT services
BT test mode
so is one of these the file that would determine what path audio would take in any given situation? (e.g. headphone jack occupied while BT headset connected, desired paths media>headphone phone>BT)
I REALLY need to fix this before my 30 days are up or phone probably going back.
I got my hopes up when I discovered the 'secret menu', but I don't see any setting in there that seems appropriate.
I've tested with the superclean 0.7 DL30 rom and this same problem still exists
Please let me know if anyone finds a solution.

stupid ass samsung friggin morons!
It looks like this is a problem on other Samsung Galaxy S phones as well, see a thread and app someone made in the Epic forums.
http://forum.xda-developers.com/showthread.php?t=842571
it is just the phone app
this problem is extremely frustrating. if i have headphones plugged in the mic works just fine. the mic is only turned off when i use an AUX cable. It would be nice to be able to drive and not have to worry about unplugging the AUX cable everytime I wanted to use my phone.
I downloaded the Epic app they made over there but all it did was hard lock my phone with my first test. I dug into the code but I'm a wee bit over my head so I'll hit up the books and see if I can't work with the guy who made the Epic one to see about getting it working with our phone.
This was with the .7 superclean DL30 rom, I'd love for someone else to try one of the other DL30 roms and see if they have any better success.
I contacted the author of the app and he replied back stating he had a buddy with a fascinate test it and it worked fine and that it might be an issue with the busybox version included with the .7 superclean 2.2 rom I was running and that it relied on busybox having the pidof command. Later tonight I'll dig into this a bit more and post back hopefully a fix and instructions on hwo to ensure this is working
I got this working http://forum.xda-developers.com/showthread.php?t=842571
The Froyo version works just fine on the original DL30 leak and on rubiks .3 DL30 but does NOT work on DL30 super clean .7 or .9. In .7 I got a hard lock that I had to do a battery pull to fix and in .9 the app ran and looked like it worked, but the audio routing did not change as expected.
All credit to cicada, I did nothing more than test it
I have not tested this on any 2.1 ROMS

I am on original DL30 leak and did NOT work for me... at least with Ambling Book Player. Not sure if it matters what app we are using to play media file. It shouldn't, but this whole problem should not exist. SAMSUNG morons!
Ok so i tried with my Rubiks DL30 ROM installed. The app opens up, no FCs or bricks or anything, but it doesn't work. I had my wife call me when i was driving, I picked up and she said she could hear me but I still couldn't hear her. I'm assuming that the car's mic is functioning but it still doesn't fix the issue. Is there a bluetooth adapter out there i can stick in the aux jack? Well i guess the first question should be, can the phone handle having two BT devices connected at the same time? i.e. hands-free calling and BT audio adapter
I'd say maybe try another full wipe and re-flash. I've switched over to the superclean EB01 roms, currently on 2.3 and hasn't had any issues with this working on 2.1, 2.2 or 2.3. I did have 2.2 initially not function with this tool, similar to what you reported above with it looking like it was working but not actually doing anything but a full wipe and reflash did the trick.
ok... thanks, at least you've run into that problem so i'm willing to give it another go. I'm currently on SC 2.4 so i guess i can be your guinea pig
I'm on SC 2.4 currently and had it stop working on me again. At work now but I'm going to try setting the app off and then back on, I have had to do that sometimes when flashing as the files get overwritten. This was working properly in SC 2.3
Hey man, thanks for the updates and info... you're really like the ONLY person that's giving me any hope on this. I thought the compatibility issues were busybox related? So I don't see why it wouldn't work on SC2.4
Would someone please fix this on Fascinate... ? pleeeeezzzzzz
Hello Folks,
I just replaced my old Droid Eris (that I took swimming) with a Samsung Fascinate that I bought from a guy on Craigslist.
The phone is in pretty great shape, and it is wonderfully faster than my old Eris was (especially after it went swimming).
The stock rom was disgustingly hogged by VZW and M$, as I'm sure you all know. I am currently running PowerWashedGB on it, and it is fabulous.
I am having a problem however with audio dropping out during streaming, and am trying to decipher whether it is software or hardware related.
Does anyone else have problems with audio dropping when streaming? Works great when read off a disk. I went back to the VZW stock rom to see if it had to do with PWGB, but the problem persisted.
Does anyone know a way I can pick this problem apart, and if there is a different radio/modem I could try flashing? Everything else on the phone works great, even data for the most part, just not stable enough to hold a steady stream (drops every 30 seconds or so for about 5-10 seconds).
Thanks guys.

Do a *228 options 1 and 2 and let the phone reset. If the problem persists: does it happen with only one streaming app or with all of them. If it's all of them try streaming with the charger plugged in to check if it's a voltage issue with the screen off. Lastly, does it happen with the screen off or on or both ?

Thank you for your quick reply. Setting the phone to reprogram seems to have fixed the issue, I've been streaming about a half hour now with no problems, which is far more than was working previously.
Hello all,
I was hoping someone could point me in the right direction to a Gingerbread ROM with a working media start/stop/call end headphone button (I'm using the OEM headphones that came with the phone) and 911. Both of these issues are documented bugs.
I've tried CM 7 and a couple of MIUI ROMs and the non-functioning headphone is pretty much a deal breaker, as I use my Vibrant for podcasts more or less everyday; the fact that 911 doesn't work just seems dangerous.
I've scanned lots of posts for different ROMs and neither issue really seems to come up telling me one way or the other and I don't have a day to load every single available GB ROM and figure it out via trial and error. Search hasn't been particularly revealing either.
For now, it's back to Team Whiskey NextGen v2, but I've tasted Gingerbread and I like it.
Thanks for your time.
The 911 issue should be fixed in the future. As for the head phone button issue - it will never be fixed until the GB source drops for our vibrant.
The button function is a kernel issue, not a ROM issue. The current kernels are ports of other phones hacked to work for our phone (thus another reason not so good battery life). (IE: I9000 kernels)
Don't hold your breath - don't think GB source will ever drop for our phones - Samsung dropped us like a wet diaper.
I was running CM9 nightlies, which worked great. Then I flashed back to an official ROM and updated to the official ICS. Now I'm getting frequent disconnects when listening to music via bluetooth audio (bluetooth speaker dock, in-car bluetooth, etc). I never once had this issue with CM9 nightlies.
Anyone else experience similar issues?

I am too. Never had a problem with Gingerbread but just upgraded to the official ICS and it's freaking annoying.
I'll probably be switching back to CM9 nightlies. Even in its pre-beta state, it seems far more reliable than the official ICS ROM.
I do really like Samsung's music player app, though. I only wish I could install that on CM9 somehow.
If you are having BT disconnects on ICS,
Try plugging in the charger while testing it. The phone won't enter deep sleep while charging.
Some of the BT devices are not playing well with ICS.
My BT under ICS is about the same as under GB (all stock) except that my headset pause/play button no longer works under ICS.

Well, CM9 is ICS and I had no issues with my BT devices. It's something unique to the official ROM.
Maybe there's a way to modify the BT/sleep behavior on the official ROM, but at that point why not just use a custom ROM that works better?

I started having trouble with BT disconnects a few months back when I began testing Shostock2 and AOKP custom roms. I think custom roms are great, I just prefer Shostock2.
The charging cable plugged in work around will be my best suggestion for non-rooted ICS with BT disconnect issues.
My thread on this is:
http://forum.xda-developers.com/showthread.php?t=1609686
I'm still using Tasker to avoid the problem.
Probably something changed in the BT software somewhere...
I'm getting high voltage warnings with the stock ics and once the battery passes 35 percent it drains quickly. If I plug it to charge the phone just gets hot I have to restart to get it to charge

I installed the F1 Galaxy Nexus ROM (ICS 4.0.4) and never had any problems with Bluetooth disconnects. So hopefully it's fixed now. I'm dl'ing the latest ShoStock 4.0.4 and will see if it's fixed as well.
