[PRJ] Improve Bluetooth in Car - Nexus One Android Development

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.

[Q] headphone jack is hijacking my bluetooth

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

Bluetooth and Thunderbolt

I know there is alot of issues with bluetooth for the TB. I was able to have full A2DP streaming with my DINC in my car but the TB and EVO wont even connect at all. I have a Sony XPLOD MEX-BT3800U. I was just wondering whats going on with the hardware compatibility and if there are any possible ways to create compatibility. What exactly is not compatible? Is it the ROM, KERNAL or RADIO? Hardware or software profiles? If someone could answer how it all works from a development / engineering standpoint that would really ease my mind. Just curious if I should throw down another few hundred on a new radio for my car or if I should just wait for software fixes.
Thanks

Personally , I would wait for a software fix. But sometimes that might not help also. But I have some issue sometime when streaming to my radio bluetooth with a little disorder sound sometimes. Very lite.

I had a similar problem with my factory radio on my Ford Fusion. I resolved my problem by updating firmware on the factory radio (MS Sync) and running the leaked radio update for TB and a stable Rom like Perfect Storm 1.4 and 1.11 batsaver kernel. My issues were resolved, I was having problems with pairing, when it would pair I would lose connection within 1 to 2 min and could not regain. Very fustrating. I attribute most of my issues with OC of TB I was too aggressive running what I thought stable at 1.5 Ghz.

I had some similar issues with my stock TB loosing bluetooth connectivity with my car. I would get in the car, it would connect, then a minute later disconnect. Turns out, I was able to fix it by unpairing, then reparing; and denying permission for the car to download the phonebook from my phone. Something in my contact list was causing the issue.
Weird about the phonebook

I have the Sony MEXBT2700 and it worked great with the tb at first, but then it, the tb, started acting up whenever I would turn the car off. This was one week after launch day for the tb. It would literally cut all sound off on the phone till I restarted, so I ended up calling verizon, then sent me a new phone about two weeks after launch day.
Since then it has been working perfect, sq isnt great, but its better than doing bluetooth from my Macbook pro.
If you've got a Ford with Synch
Just in case you've got a Ford vehicle with Synch, there is seemingly random problem that sounds like this and I posted some info over at Ford Syncmyride site. In a nut shell, simply pull the fuze for the system wait about a minute and then replace. If you're like me and you couldn't find the correct circuit disconnect battery cable.
Seems the system needs to do a "battery pull". Only have experience with the Ford Sync but that's my .02 and I hope it helps.
I have sync in my '08 focus and i've never had issues with any of my phones streaming music or placing/receiving calls.

Bluetooth with my TB to my JVC headunit has been rather problematic for me. What I did finally discover was that if I didn't allow for phonebook syncing, all is well. I am currently on Das BAMF 1.6.1 and now have perfect streaming of music and calls as long as I deny that silly phonebook.
Hope that helps.

Sometimes I wish I kept my phone stock
Yeah, this is killing me...I'm dying to move to ICS but I'm constantly using A2DP streaming.
C'mon HTC, leak, baby, leak!!!
Gotta reboot the phone to fix the streaming or go back to a GB based rom.
A2DP is a critical feature for me. That is a main reason I'm keeping my Rezound stock until 4.0 is released. Then I will consider the value of rooting and flashing ROM's once I have had a chance to use Sense 4 on top of ICS.

I'm on GB, and with my girlfriend's Durango with uConnect (brand new car), I can connect bluetooth and make phonecalls without issue.
But when I stream music, the stereo seems to put out like 5 seconds of music at a super high rate of speed ,then waits a few seconds, then again, then waits a few seconds, then again.
IT's like instead of hearing Nirvana, I hear Alvin & the Chipmunks for every second or two and silence the rest of the 5 seconds.
Anyone else have this problem on Gingerbread like I am? I am on the latest OTA kernel that 2.01.whatever it is.
Awkward though!
I got my Jaybird Bluetooth buds a couple of days ago and every I disconnect them I have to restart my rezound to get them to stream music again, that's the only fix I found for my ICS 4.01

on ICS 4.0.1 BT audio streaming works once after a reboot. anytime the devices are disconnected you will need to reboot the rezound. Phone calls work fine
on ICS 4.0.3 BT audio streaming does not work. phone calls work fine.

Nope. BT music streaming worked in my car, Gen 3 Prius with stock stereo, with stock ROM & kernel and is currently working with Ineffabilis GB and all kernels I've tried (stock, dsb and AnthraX).
The GB ROMs work fine. It's not necessarily true on the working once after a reboot. There's other factors at work. I tested this extensively while I was running Nils business sense and there were times I would get it to stream two or three times in a day without a reboot. There were other days it wouldn't connect at all without the reboot. I finally got tired of messing with it and jumped back to GB. This was on a Kenwood head unit with an add on BT module.
Fixed guys will be in my next rom
This is working perfectly in Joelz New BAMF ICS Rom, I will find a link and add it to my post.

How do I fix my bluetooth audio streaming ? It used to work on gb but with ICS using the stock music player songs won't start
Thanks in advance
That was from two months ago. Could you give us a little more specific information.
Ops. Sorry for that.
Since I have flashed my Samsung S2 into a rooted ICS via odin I can't no longer stream music via bluetooth to my car audio.
This was a bluetooth pairing I made before I did the (no-wipe) flash. I perhaps have to remove the pairing and do it again.
Anyway, as I select a song it starts for 1 or 2 second and than it stops. This only when the input of my car stereo is "Bluetooth player". As soon as I select another input on the stereo, the song gets unstuck.
Also, even if the car stereo recognise the mobile via bluetooth, the audio player is seen but on the stereo display it's called " Unknown device" instead of what used to be Samsung S2.
EDIT :
I have just deleted the pairing and paired the phone with the car stereo and it works perfectly. Sorry for wasting your time mate

[Q] Little Annoying HOX+ Issues

OK so I've had my HOX+ for about a month having moved on from the Apple empire and for the most part I love the phone. There are a few annoying things I've noticed and after much time searching forums, contacting HTC and all that jazz haven't found a good answer yet. So I figured I'd just try asking and getting some opinions here. My disclaimer is that I'm still 100% stock and not quite ready to dive into root and custom ROMs yet
Issue #1 - that damn BT call audio issue - Has anyone found a fix for the BT issue so everyone I talk to in my car doesn't sound like they are talking with their phone in their mouth? I spent a week working with HTC on this and all I ever got was the standard "we're sorry to hear about your issue, working to resolve, blah blah blah"
Issue #2 - I've recently noticed a issue with audio pausing and the phone being slow to respond from unlock when playing music. PowerAmp seems to be the worst culprit but I've noticed this a little with Double Twist also. I've tweaked my audio settings in PA to use the "huge" buffer and highest thread priority. Turning Beats off didn't seem to help either.
Any feedback welcome, thanks.

Yeah that sounds almost exactly like my problem, little minor pauses most of the time (which to me is kind of annoying) and every so often a longer pause of like 4-10 seconds. I ended up having my phone go into a sleep of death last night so I rebooted and also ended up removing the Double Twist widget I had up when I was checking out different players. Today the pause issue seemed better but still not 100% so I'm starting to suspect something (widget or otherwise) I'm running is maxing out the CPU or something.
Haven't noticed any balance issue though, what player are you using? I know in PowerAmp and I'd imagine others there is a balance control...could just be off a bit or if nothing else you might try adjusting it to compensate till you find a solution.
Stock based and aosp roms have Bluetooth fixes.
You can't fix anything yourself unless u root, otherwise wait for a carrier update that may never come.
Will also fix any slow performance issues you might be having, even more so with a custom kernel.
Never experienced issues with Bluetooth myself tho.

I haven't tested to see what happens with bluetooth audio streaming. Only happens/has been tested happening with AUX.
This happens on the latest viper rom for one x+ att
We should fix this!
use Zplayer

I have had same problems with music, tried Zplayer which solved the issues... my phone is on stock rom ...
Had a chance to do some heads down work and played music for the better part of 4 hours. The pause issue is still there with Double Twist, but nowhere near as bad when I was running stock. Very minor now bit still apparent. My PowerAmp trial ran out so I can't test it. Might try Player Pro even though I'm not crazy about it.

I have noticed minor pauses in music at the same spot when walking down my road towards my house. Due to it happening in roughly the same spot, I have put this down to my home WiFi connecting and/or my Vodafone Sure Signal signal booster being picked up as the primary network connection for calls etc.
I have no idea if my thoughts are correct, but is this something anyone else has tried or even thought about? My phone is currently fubar'd so I can't test it atm.
I hv tried few ROMs and concluded that its the stock kernel's processor settings on sleep mode, I installed cm 10.1 with blade kernel and changed minimum CPU frequency at bit higher level and music plays perfectly fine... I hope this could help others.

Yes, I have found that the audio pause issue seems to be related to connecting to a wifi spot. It still happens when wifi is turned off though, so although they are related, it's not the cause.
I definitely think it has to do with the clockspeed of the device when it is idling.
I notice the audio pauses when,
The screen is left on and the orientation changes
pause frequency changes depending on the player
When connecting to a wifi access point/scanning for one
Someone take this information and e-mail HTC. I was going to call them, but I don't have the time to deal with all of this stuff right now. College finals are next week.
EDIT: managed to give HTC a call. They suggested poweramp and said that they were working on a proper fix. I don't have the time to test to see if power amp solves the issue just now, but it's always good to hear other people's experiences/devices specs. So let me know your device specs and what you know about this issue!

[Q] Distortion on bluetooth audio?

It appears that the HTC One stock ROMs suffer from the same bluetooth audio distortion that was plaguing the N4 and other AOSP 4.1.x and up ROMs until recently.
Can someone please test some mp3 audio that is:
- Local on their device, bitrate higher than 256kbps
- streaming to a set of good speakers that can reproduce high frequencies well
Play some Led Zeppelin or jazz that has lots of cymbal work, or some vocal music, and listen for distortion on the cymbal crashes or the 's' or 'ch' sounds.
I don't believe it is just me. HTC One Sprint users are reporting the same. I just want to make sure it isn't just them and my unit or something.

I can confirm it does. Had the Nexus 4 and right now I'm using the HTC One (unlocked). Thinking of getting rid of it since my T-Zones does not work with it.

Sigh. 3 steps forward, 4 steps backwards (at least for me). That distortion is terribly grinding on the ears.
CM10.1 will save me! When it is released...
Just FYI, tested with AOSP CM10.1 ROM and the problem is gone. It's definitely a bug that exists in the stock Sense 5 ROM.
I thought I was the only one (no pun) with this issue. It's very annoying. I hope the stock version gets fixed soon.
Anyone with the recent sense updates have any improvement on this front?

Can I bother you guys to test the problem with wifi disabled? I've heard that that may help the problem...

Doesn't make a difference. Using the 4.2.2 ROM too. Sorry for the late reply bro.
have never had any distortion on any of my audio using my hTC One with good speakers in my car and connected to bluetooth

I have a Sprint HTC One, but the Bluetooth problem is the only reason I keep going back to ViperROM from CM10.1. My Bluetooth (Jawbone ERA) works fine for music and other media sounds, but phone audio is completely messed up. My speech is not getting picked up at all, and the remote party sounds garbled. I also tried disabling the WiFi per your request, but that had zero effect. I went from a 5/27 nightly to 6/19, but the Bluetooth phone audio issue has remained.

I have a T-Mobile HTC One and same deal... had Dirty Unicorns installed and bluetooth music/etc worked great, but phone calls were just a fuzzy, distorted mess. And since I still use my phone for calls (and rely on a headset for work) it was unusable.
Right now I'm rocking a stock rooted ROM since I haven't found a ROM yet that works well enough to be my daily.
