[DEV]How to fix bluetooth audio in AOSP ROMs

Hey there devs. I just fixed A2DP for VanillaEclair, and I have to share this. Now we can all provide full-featured AOSP-roms, so good luck with tweaking your kernels!
Apparently the solution was simplier than we all thought. We had a missing bluetooth firmware file. Put this to /system/etc/firmware and you'll get A2DP working properly. I got this idea from Darchstar, while I was looking at the firmware file in his rom. Damn... we could've fixed this months ago! So... enjoy and let the fun begin!
PS: unzip this, of course...

Ah, you little bugger You beat me to it.
I actually saw this yesterday while trying to pull proprietary files to compile Cyanogen's Hero port, and noticed that this exact file was missing from my phone. I didn't take too much notice of it until I realized what 'brf' could stand for (Bluetooth Radio Firmware). Was just busy experimenting around this morning
Anyway, well done on the fix - you've made a lot of AOSP lovers happy Might I suggest that you possibly look for further missing files that may solve some other hardware bugs (maybe trackball LED?). I'll see what I find missing today in the ROM.
Mr P.

solved yesterday ....

You've ported Darchstar's ROM, eh? Damn file, this could have been solved for ages. But it's good to have it now anyway.

cheer for you

missing firmware? I had a feeling the problem would be very simple
gonna try this on aHero .. thanks man

but what I think is not enough in some cases, I also worked on the driver liba2dp

The firmware file itself fixes the issue. Nothing else is required.

great! it works! thx

I have not had a chance to test it with my edits, though I now also works on bluetooth transfer after work on liba2dp

Now we have it sticky. Thanks Fallen Spartan!

One thing to keep in mind: although the term A2DP is thrown around a lot when talking about bluetooth audio, A2DP has been working fine for a while now. A2DP is the bluetooth profile for high quality uni-directional stereo sound. HFP and HSP are the profiles that allow you to actually talk to someone on a call.
en.wikipedia.org/wiki/Bluetooth_profile
It doesn't make much of a difference when conversing with others on the forums, but if you are actually diving into code it makes a huge difference.
This is ignoring the fact that the problem could have been bluetooth not switching away from A2DP properly or some other such problem, but that didn't seem to be the case because headsets that don't support A2DP still did not work right. This is also assuming that the bluetooth stack in these devices don't depend on A2DP code for all audio over bluetooth as I have not looked at much of the code.
If you already know this, then sorry for the post, but if you didn't, it might save you many hours of banging your head against the wall. On the other hand, if you know for certain that the A2DP code is used when making a call, I'd like to know that as well so I don't get frustrated figuring out how it all ties together.

I'm not banging my head. mine is the first rom that works on bluetooth audio.
However, as I wrote in the post, in some cases may be associated with
A2DP, in fact, I added the firmware missing

Like I said, if you already know all of that, then sorry for posting it. There are many on these forums that don't know the difference though, so maybe it will help them. Most headsets don't even support A2DP, my Jawbone Icon only recently got support for it (yay!).
I currently use your rom as I need one with a BFS kernel. The Audible beta app runs with barely any stuttering with it, whereas those with higher end devices are complaining about the poor performance. Thanks!

What's the point in saying you have fixed it first if you didn't even bother to share? Many things appeared in my ROM for the first time, but I didn't even mention it. We both went out on kicking some guy's ass because he wasn't helping the community, but it seems that you didn't have that in mind either.
Anyway... now everything works in the Vanilla ROMs and that's good.

I've simple answered nebvin ....
I do not understand why you have to start a war for anything.
I was going to share (you ask xenoside) but have not had time to make a package to flash.
collect information before judging.

robin04

I knew it! I knew it! I knew it! Why did I not follow my instincts on this! I saw all the other ROMs from the G1 area and they had this file. But I should have realized it!

RaduG what's the difference between this and brf6300.bin? Do we need both?

I don't think we need brf6300.bin. Here's the difference:
BRF6300
The BlueLink 5.0 platform from TI is a highly integrated, digital CMOS, single-chip solution supporting Bluetooth® Specification v2.0 and all software needed for Bluetooth operation.

Click to collapse
BRF6350
The BlueLink 6.0 platform from TI,BRF6350, integrated device includes Bluetooth baseband, RF transceiver, ARM7TDMI®, memory (ROM and RAM), power management and an FM receiver.
Click to expand...
Click to collapse
So these are two different chips, and we have only one inside our heros. What's curious is the fact that the taiwan 2.1 ROM only included BRF6300 firmware and A2DP works with that. One more interesting think is that apparently BRF6350 includes an FM reciever, so in theory we might be able to get the radio functionality.

I see. Thanks!

Recommend a build with BT headphone support?

Hi Folks
New here, been trying to find a good build for my new TP.
The last one I tried was the XANDROID 2.1 AOSP build that is popular right now.
I had a couple of 2.1 builds before that. All builds say BT works...but no luck.
I'm trying to find a build that the AD2P BT headphones work ok. I'm running the Plantronics 590a headset. All of the builds I installed so far, the sound playback to BT is super choppy.
I've tried searching the forum for AD2P and BT headphones...but I haven't had any luck on a confirmed build...minus an old sense build by KlinuX that I'm having trouble getting to work...
Anyone know of a build with BT headphone support working ok? Or any fix I can install for the BT stack?
Thanks!

Bt isint exactly in a perfect state, i would not advice to use it for a headset, but hey some else might disagree with me.
and i cannot stress this enough, next time please use the search function on the forums.

man am so glad to see youall bringing up this topic about bluetooth i recently tried one of the android products i have the motorolla s9 bluetooth headset and when i pair my device to the phone yes it was choppy so i was looking all around to see if there was a fix damn oh well i guess we gotta wait some longer for the other builts to come out but i find there moveing slow on the production of them even they havnt gotten the camera to work yet what is takeing them so longgg

Seriously guys? You're really going to whine and complain about how it's taking them so long?
Jump into the code and help! If you can't, then you are not allowed to complain .
They're working on it, and are well aware of the issue. The devs are doing this in their free time, no body is getting paid to do this work...
With that said for the most part all of the builds have the same functionality. There may be little differences here and there, but it's not like one build camera works or one build BT works perfectly. So please continue to wait patiently, donate to some devs, and learn how to write device driver code

[ROM] MIUI Port

This ROM is in no way suitable for daily use and is only shared so that other fellow developers can take a look and maybe provide fixes to one or multiple things on the "not working" list.
Take it as a very early proof of concept.
ROM DOWNLOAD: http://www.androidfilehost.com/?fid=23501681358554238
What I did to get this far...
1. I took the MI3W miui-germany ROM
2. I unpacked the MI3W's ROM
3. I unpacked the boot.img of the MI3W ROM (zImage, dt.img, ramdisk)
4. I patched the fstab.qcom and init*.rc files to match the Find 7a
5. I unpacked the latest OmniROM for Find7a
6. I unpacked the boot.img of OmniROM (zImage, dt.img, ramdisk)
7. I copied zImage and dt.img from OmniROM's extracted boot.img into MI3W's extracted boot.img
8. I repacked the MI3W boot.img
9. I bundled the MI3W system partition with the modified MI3W boot.img and uploaded it onto the internet for someone else to iron out the remaining bugs
What seems to work...
*) Basic Operation (MIUI apps, status bar, well what you would expect really)
*) Bluetooth
*) Wired Headset / Bluetooth Audio
*) RIL / Mobile Data
*) GPS
What doesn't work... yet...
*) WiFi (there seems to be some issues with wcnss / pronto / prima, this one is bad...)
*) Random Reboots / Blackscreen Glitches (from what kmsg tells me it seems to be related to wcnss, aka. WiFi drivers causing a critical error in kernel every once in a while, fix WiFi and this error will fix itself)
*) Speaker Audio
*) Rotation Sensor (and probably others)
*) Vibration
*) Skyline Notification Light
*) NFC

Good things always have the obstacles.
You've done your part. And let other(s) help you.
I don't have knowledge about cooking a ROM.
But I think someone can help. @Entropy512, can you look at this one?

If you want mae some cool port, i thikn sense rom is good candidate...

Great work
hey there mrcoldbird,
great work so far...keep it up..will definately help support you on this when it is up and running..i am not a dev but if you need someone to just bug report i am there for you,will keep my eyes n ears peeled on the thread and as soon as it's near ready i will flash and help you anyway i can...thank you for all your hard work so far

Right now we need developers involved in this. We know the countless obvious bugs.
Just have to fix them.

Awesome work. Thanks bird. Any chance you want to try lewa os while you're at it. I personally think it is better. I imagine just how busy you are but just wanted to throw it out there

Porting really should only be done when there is no source available for said ROM.
For unicorn a source rebuild might be better.

I was actually searching for people to help me with this but no one bit the bait yet.
I am continually working on MIUI, bit by bit... but due to reallife interference it goes... slowly.

Lewa OS is extremely similar to MIUI and that is why I even bothered to mention it. I know the developer is having some trouble with MIUI so I thought it would be useful and helpful to mention Lewa as it might be a project that will help the development of either or rom.
Please don't take a blunt tone with me (if that's what it was) as it only makes you look arrogant. Taking in to account our post and thanks scores it is quite clear who has contributed in a more positive way towards XDA. On that note; you might also want to thank MrColdbird in the OP for his contribution, which you have not done as of yet but you seem to be poking your nose in to the thread
That is all
Edit* I apologise MrColdbird if my suggestion was unwarranted.

I am setting up a build environment and will be looking in to it; starting with wifi. I think I might check out lewa as well.

good luck

I've pm one of the Miui dev from note 1 community, and hope that he willing to lend his hand for you @MrColdbird.
Mr @Gerrett, can you help him? If you got some free time. I know you so busy. But at least, just a little guide for him.

Actually I've got 99% of the issues resolved already by using a different port-rom in conjunction with a few OmniROM injects.
At the moment only the proximity sensor (screen off on holding the phone to your ear) and nfc are broken, lte works, but needs to be reselected every time the phone reboots via the service menu (dialer code).
Sadly, I'm not allowed to share that (quite nicely working) ROM just yet as I switched port-bases to a unreleased chinese one in favor of the MI3W port-base.
Until that chinese author releases his first public port base-rom I'm kinda bound by the promise I gave not to unveil things early.
Just hang in there, it shouldn't be long until you guys have MIUI on Find7a... all I can tell you is that it works nicely and without any critical flaws I can see except those mentioned above (which we will get fixed too eventually).

[Q] No Music Audio on AOKP - Need a fix!

Can any one help with this? I'm by no means a noob with rooting and adb and what not but, I somehow managed to get my M8 soft bricked yesterday and the only rom I could manage to sideload was the AOKP rom because it was under 1 gb. I'd like to hang on to this rom but the audio isn't working out of the headphone jack or out of the speakers when listening to music specifically with Google Music. Youtube and everything else seems to work..
Thanks for any help :good:

you'll probably get better answers if you post in the AOKP thread..sounds like a kernal issue though

I sorted it out. It was Google Music maxed out with devices (max is 10) Of course I didn't get a warning or any of that.. I just happened to guess that might be it. Google needs to make that more clear.
I was going to ask the question in the ROM thread but even though I've been a member of XDA for 3+ years I have less than 10 posts and can only use the Q&A section

Please let me know if it works ok i dont have this device to test on. MAKE SURE you have a rom back up so you dont have to Odin if issues arise. I'm very confident that it will work fine tho. Thanks

Will try this out in a few hours! Thanks for bringing your mod to the s6 edge. It is awesome!

Your welcome buddy...let me know if it works ok. Thanks

Well i guess its working. 106 downloads and not one ty clicked or one response yes its working. Pretty sad. I knew there was alot of selfish people on the web but this is pathetic. One hudred and six downloads. No respect, no appreciation. .im fighting myself really hard not ro remove the links. Really hard. Change my mind people please.

So sorry for not getting back. I used all day today and it was awesome. I made calls on speaker and watched YouTube and everything was perfect. Really great mod and I will apologize for all the edge users. Can't believe no one said thank you. Pretty sad actually

My remark wasn't targeted towards you stu your a great person. It was for the other 105 people who are using this, who wouldn't even have it if it wasn't for you requesting it and supplying the stock files so i could mod them. Selfishness is part of human nature, but the level of it in this thread is enough to feed all of population in NY. I'll stop my whining now, you get the point. .lol ?

I do this for my own devices and share it, then if anyone requests it i do it for them also. Everyone in between is just lucky. I could have easily pmed it to you and called it a day.

I just downloaded for my TMob S6 Edge model and about to give this a whirl. I'm a strong Viper advocate and wasn't sure if your mod will happily coexist. Will Nandroid first then get back. Much appreciate your contribution.
EDIT: Killer sound MOD. Works fine with Viper. My thanks again.....

I use it with viper also and it works great but i use the medium sound or even the stock sound if yiu use viper. The loud is a bit too much and it may cut out for some...glad u like it

Well I tried flashing in twrp, no go, the phone reboots into twrp before it flashes anything. Suggestions?

Thank you. This works great!

Not sure what that is. Its working for others so cant be the zip. Try downloading the zip again and make sure you have the newest twrp..

Well i tried it again, could it be because I'm not on a stock rom?

No it should matter. U said its failing in recovery right? Trey extracting the files in the zip and replace yours in system/etc

worked flawless on w8 canadian edge thank you sir makes it really loud

Got it working awesome!

What values were changed in the mixer_paths.xml compared to stock? And what base is the file sourced from? Latest DOI1?

Turns out I'm an idiot. Was a bit loaded on vicodin yesterday and failed to realize that this is the S6 Edge forum, not the S6 Edge+ forum.
Well, it works in that it enables the handset speaker, but in doing so it seems to disable the main (bottom) speaker. So I only have sound coming from the handset speaker. Unfortunately, reverting to stock doesn't seem to have fixed the main speaker problem...so no I have no sound lol. I'll see if I can pull the xml file out of another ROM or something.
Seems like a bad ass idea though.
Edit: Actually, this only seems to be the case with the youtube app. Everything else is working fine as far as I can tell. I'll mess with the app and see if I can figure anything out.
Edit 2: It's not the youtube app, I think maybe it's a certain protocol or something. System sounds and recorded video works fine, for example, but anything I've played from youtube only comes out of the earpiece. On Facebook, some videos play sound through both speakers, some only from the earpiece.
