Different bluetooth stack?

Hi everyone,
The bluetooth on my GSIII has been a complete failure. You can follow the saga here (http://www.benzworld.org/forums/w245-b-class/1662643-2009-w245-samsung-galaxy-s-iii.html), but basically it connects to my car and has no sound with the stock ROM and refuses to connect to the car at all with the AOKP JB build. It suggests an android problem, so I'm wondering if the bluetooth stack can be reloaded to reflashed with something different. If anyone has any ideas, I'm all ears. Thank you!

I have a problem with one of my Bluetooth devices dropping and reconnecting. Not sure why is just one. It works fine on an iPhone. I'm guessing your GS3 isn't the international version?

Sweet! please let us know!
I'm having a different issue. it connects and stays connected, plays music but it doesn't list the song/artist info on my eclipse screen but the SG2 will..

Update: no change with the new kernel. The phones pairs but there's no sound, just as was the case before.

Try CM9. Bluetooth works much better with it. CM10 should have it fixed as well in a day or two.

Here's a 'six months later' update. My phone went through various android updates and I'm now on Android 4.1.1 (up from 4.0.4). The problem was still not solved, but instead of no audio, I now have one way audio, where people hear me but I don't hear them through bluetooth. I have also gone through a number of custom ROMs and kernels for my phone (including CM9/10 and AOKP) and nothing helped with the issue.
A couple of days ago, my girlfriend's HTC One X (finally!) got its Android update, also from 4.0.4 to 4.1.1. Her phone now works like a charm with the in-car bluetooth.
The solution I ended up with was a car cradle and a couple of NFC tags to control my phone in the car. My NFC tag that's stuck to my car cradle turns off WiFi, starts car mode, starts a car home app and turns my volume to max. All I have to do after that is connect the 3.5mm audio cable and I use my phone in place of the car's infotainment system. That way the phone integrates into the car as well and the only thing I lose are the steering wheel controls (they still work for volume).
My less technologically inclined girlfriend now has everything work auto-magicallly with bluetooth. So I guess all's well that ends well, but to anyone considering a US-spec Galaxy S III, watch out: the bluetooth issue is still not fixed. If bluetooth is critical, consider the HTC One X (but be warned: it has awful battery life!)

I have no issues with stereo Bluetooth and mono Bluetooth. Everything and everyone hears and plays fine. It might be an issue with your headset.

Colby. What version of android, kernel / rom combo are you using?? There's SOOO many people having problems with JB and bluetooth, regardless of rom or kernel setup.
If you're on stock... just nm then.

What's wrong with stock? I have no major issues with streaming BT from my phone to my Mazda 3 head unit, or to my Sony MW600 earphones. Even track titles work (the only thing that doesn't work is time display). In my experience, Bluetooth works best on the stock ROM.
Stock Rogers ROM (DLK4 - JB 4.1.1), rooted
KT747 (1/9/2013) kernel
CWM Recovery 6.0.2.3
PlayerPro Music Player
On my old Xperia X10, I had CM7 and had no end of issues with BT:
- Sometimes it would connect and there would be no sound
- Sometimes it wouldn't connect at all
- Sometimes it would cut out after switching songs
- It would stutter a lot whenever Wi-Fi was enabled (but I think that was a problem with the Xperia).
When I tried CM10.0 on my S3 I had similar connection issues, just not as bad. Also, the volume gain over BT was much lower, so I had to turn the car speakers way up. Stock 4.1.1 doesn't have any of these problems. The only problem I had was the audio switching over to speaker after turning off the car, but I fixed it.
Also, BT is apparently broken in 4.2.1 in general, not just CM10.1. Google confirmed a BT patch that works on the Nexus 7, due for release with 4.2.2: http://www.expertreviews.co.uk/smar...confirms-android-4-2-bluetooth-streaming-flaw
TIP: Don't forget to turn up the volume on your phone. I don't know how many times I accidentally turned down the volume and thought that it wasn't working. Now I have Tasker do it for me whenever I connect. :good:

4.1.2 has Bluetooth working use it everyday. (Stock and ROM.) Can't tell u which combo I use at a time. I flash a different ROM everyday. As 4.2.1bluetooth is broken expect for task's AOKP. He has it workingish.
Now as connecting to a car. Depends on what it connects as. And I've learned going to and from ROMs when u connect a source hit the volume up 9/10 times it works

Help with BT headset problems on cm12.1 (SM-T700)

Hello guys.
The thing is I used to run the latest CM12.1 on my SM-T700 a few weeks ago with no problems at all, it was smooth, until the other day I decided to buy me a pair of Bluetooth Wireless Stereo Headset from radioshack. The pairing was successful; the problems started when playing audio from any source (Spotify, YouTube, Netflix, etc) the audio was lagging really bad, like stuttering, coming with "sound holes" in between, and it was really annoying.
I realized the problem wasn't coming from the Bluetooth Headset, 'cause it works perfectly with other devices running CM13. (LG Optimus L90 for instance)
I tried a few things before running to you guys for help:
-Turned off experimental NuPlayer by default (didn't work)
-Clean Flashed CM12.1 like 5 times (didn't work)
-I even tried a few other ROMS based on CM, the problem was still there.
-So I went back to IronROM 5.0.2 and the problem is gone. :good:
Of course I want to go back to CM12.1, IronROM is awesome but CM is the thing nowadays, so if any of you has an idea of what is the origin of the problem and can guide me through the solution, I'd be thankful for life.
Have a good day!

It's a known bug in CM12.1

Bluetooth issues

Hi. Wondering if anybody could help. When I connect my oneplus 5T to my car I have problems. When it starts to call it disconnects the bluetooth from the car completely. However the call continues on the phone which is a complete pain as you cant use it through the hands free. Car is a BMW 630CI with pro nav if that helps.
Many Thanks

i first had problems to connect to my audi A3 bluetooth ... it simply didn´t find it
after trying again and changing the bluetooth audio codec it suddenly worked ...
Idk if it will work for you, but you can try changing the codec and se if it helps

Hi. Ive tried all 3. It connects fine and I can see my contacts but as soon as I hit dial it disconnects from the car.
Very strange.
Thanks for the suggestion tho

with mine in my car it every now and then gives me this a crackling sound.. Kind of irritating, I'm hoping a software update down the road fixes this.. I've tried all 3 codecs

Having issues with Bluetooth connection on my Prius Prime as well. It always disconnects, I had to disable Bluetooth on the phone and re-able it for it to work.
I experience the same with my Boss QC35. First connection, audio breaks with lots of noise and had to disable it and re-enable it.

Still found no solution. Hope the next update sorts it out as the bluetooth seems a mess.

So after looking around, there are issues with certain codecs and devices connecting being posted in the OP community forums. My Sony WH1000xm2 headphones stutter when using AptX HD. My JBL Everest 750NC's - if you turn the volume up too high, they disconnect from the phone. In my Cadillac ATS, whenever you place a call it'll stay connected, but you won't hear anything, and the other user can't hear you either.
I think they've acknowledged the issues and are working on them, but after putting Oreo on my Moto G5 Plus and Oreo's ability to change between all codec's on the fly (including native LDAC support!) I'm anxiously awaiting Oreo to be 'officially' released.
I'd say just be patient.. I'm sticking with this phone because I think it'll be worth it in the end. Wish I had better news!

so I resolved my Bluetooth issues by flashing FreedomOS. Now there is no intermittent crackling sound now and there is no issues at all ymmv, this was just my experience.

Thanks. Will wait for Oreo and then try different roms if it continues.

on FreedomOS before, it was giving me headache re-connecting to my Subaru car bluetooth, like after you shutoff engine, go somewhere and come back, unless you manually force connecting to the car, it barely auto reconnect back.
And also takes so long to get data sync from my Fitbit chargeHR to the app.
I don't think this kind of bluetooth issue related to what rom we have but the kernel and more specifically BT firmware.
-----edit-------
My friend also got BT issue when he tried to connect to BT headset. Hope Oneplus get something fixed on new oreo or updates

Just an update. Since upgrading to the official Oreo rom my problems have disappeared and my phone now works fine with the car Bluetooth.

I still have problems. Pause and unpause, and the track restarts. After ending a phone call the track restarts. 2018 RAM, Uconnect

With stock ROM 4.7.2 bluetooth connected only for a few seconds with my Audi A6. With every following stock ROM version it didn't even connect.
I tried every single Audio-Codec and the different settings in developer options - nothing helped. Once I cleared data & cache from the bluetooth system apps followed with a soft brick

Hi all,
Had same issues with my Hyundai ix35 and oneplus 5t (Nougat), tracks skipping, distorted audio in calls, etc... Tried emptying bluetooth cache, switching audio codecs without success. Now I just received the OTA update to Oreo (8.0), Oxygen rom 5.0.3 and it solved the issues!!! Yeay, no more auxilary cable hanging around !

I started from scratch but the issue persists.

I am having the same issue in my car. It no longer displays track information and the connection is not very stable. I will try switching the codec and report back.

i don.t have any volume control from the phone basically when i connect it to my car stereo
i can control the volume for the first 4-5 clicks ... and then the slider moves but there is no difference in the volume
i have to turn the volume from the stereo almost to the max
whit my old samsung tablet works great ... i have maybe 50% more volume then with my phone
tried all codecs ...

Bluetooth Headset Distortion When Making Calls But Not Music Playback(Logs)

I just bought a new Bluetooth headset off Amazon. I got the Rioddas HX 831. I have a D851 that was running crdroid oreo when I got the headset the other day. Music workes great but phone calls are horribly distorted on my end and people are not able to hear me. I decided to switch to RR just to test the headset and give it a spin since I have tried RR Nougat but not Oreo. On RR the headset has the same problem. I flashed Moun Kernel as well and the problem persist. I will post logs in a few minutes but all the Oreo roms claim Bluetooth is working so I am stumped.

After flashing custom rom, my Motorola One Action has bluetooth problems

Hello everyone, hope all is well today. Here is my issue, anytime I flash a custom rom to my Motorola One Action (XT2013-4) everything will work fine, except for my Bluetooth. While, it will connect, when trying to play music via Bluetooth via my portable Bluetooth speaker and my Samsung Galaxy Buds + earbuds, the only sound I will get is either a god awful static like noise or silence and the track will act like it is buffering within the Pandora app. I've tried a couple Magisk modules with no luck. I am usually pretty good at figuring stuff like this out, but this one has me stumped, which causes me to get annoyed and revert back to the stock rom with root, but I'd really like to upgrade to a version of 11.
If anyone can help me out with a fix, I'd be forever grateful,
Thank yall and have a great day.

Happens on any rom I try that isn't stock rom

Try changing the BT options on dev options, never happened to me but it may help.

Tried that as well, with no luck
