Hello,
I've installed nAOSP ROM 5.1 on my Xperia S. The ROM is working fine except an really annoying issue with my bluetooth headset. The voice of the person I call is really heavy distorted and impossible to understand. Also my recorded voice is not understandable. It sounds like after inhaling helium. Pairing my headset worked fine and it doesn't loose connection. I already did some research and tried to disable NuPlayer but without any effect on my issue.
The used headset model is "plantronics explorer 50" and it was working fine with stock ROM and it still works fine with other phones.
Are there any known issues or fixes/workarounds for this problem? Or other things I can do to solve the problem?
Best regards,
wewa00
UPDATE: I connected my Win7 laptop as a music player to my Xperia S via Bluetooth. This works fine. Sound from e.g. a youtube video i play on my Xperia S is transferred clearly to the laptop's speakers.
Does this Bluetooth sound issue only affect a special set of Bluetooth devices?
Best regards,
wewa00
PS: I use an "Intel Wireless Bluetooth" driver with version "17.1.1407.474" on my laptop.
UPDATE: I was in a shop recently and tried several headphones of various brands. Each shows the same issue like mentioned in my initial post.
Does no one have any idea what could cause this Bluetooth issues?

For now it seems to be a ROM issue. You could try getting a logcat and posting it here. That might help the developer.

Thank you very much for your answer. I already thought that this might be a ROM issue. Others are also suffering under these issues (see following quotes).

Hi! I have two (2) bluetooth issues. I am using the latest version (b22).
1) bluetooth headset only receives static/noise, and its bluetooth control (e.g. volume, next/prev) doesn't work
2) bluetooth keeps disconnecting when trying to pair with my car's head unit
Are there others who have experienced this or have a suggested fix?
Thanks in advance!

I was already able to logcat via adb. But could you please tell me with which arguments I should call logcat to contain only necessary Bluetooth data and no confidential personal data?

Unfortunately, I don't know what arguments are to be used to target it specifically,but what You could do is start logcat just before switching on bluetooth and end it after You try a few songs via bluetooth headsets. Logcats rarely contain personal data which are unique to Your device except Your problems.
I've uploaded a logcat to gist: https://gist.github.com/anonymous/7b8fc5a68feb5be3e1e9
I captured this logcat with Android Studio and this filter:
Code:
Log Tag (regex): BT|luetooth|bt|Bt
Log Level: Debug
I did following actions while logging:
Bluetooth on
headset connected
dialed a number
answered on 2nd phone
distorted sound on in headset and on 2nd phone
changed volume via headset buttons
quit call with headset button
started youtube video (no sound in headset)
turned headset off (phone did not notice that)
turned Bluetooth off and on again
tried to pair with laptop (didn work)
tried again, pairing worked, BUT: phone rebooted
tried several things, but could not play sound via Bluetooth on my laptop speakers
In another post I wrote that I could transmit sound to my laptop via Bluetooth. That was on another laptop, I'll try this again tomorrow.
I noticed an interesting line in the log.
Code:
E/bt_osi_config﹕ config_new unable to open file '/etc/bluetooth/ble_stack.conf': No such file or directory
. The file does not exist on my phone. And i found out that also other android users have this line in their logs. But none of them offered a solution.
Now I have two questions:
Can you get some info out of the log or do I need to modify my filter settings?
Could the missing ble_stack.conf file be the problem?
Best regards
wewa00
EDIT: @mickybart: I've some debug info about the Bluetooth issues. Maybe you could take a look at it.

Yup, I noticed the missing file in log of other users too. Probably the developer is working on it too.
This log seems to be enough, given that You have done most the the stuff needed and it has been logged.
Do tag mickybart in Your post though, so it will come to his attention too.

I now also tried to connect the laptop where I once successfully played sound from my Xperia S via Bluetooth. Today I had no luck. When the Windows Bluetooth application searches for services running on my Xperia S, it says that it couldn't find any services or maybe an error occurred. I also tried repairing, without success.

@Mirhawk: I think that unfortunately mickybart nor any other developer shows attention to these Bluetooth issues. Should I post to the developer thread, or what can I do to get their attention?

I don't think that will help much, but worth a shot, given that it is a development related issue.
Apologies, even I don't seem to understand as to what is causing the issue.
I've got the same problem with Plantronics M55, M75, M90, Jawbone Era (they're BT 2.1 or greater). But my old Plantronics ML12 (BT 2.0) works OK. As to the bt_stack.conf file, it seems to be a bt logger configuration file. See http://forum.xda-developers.com/mot...official-cyanogenmod-12-4-4-4-t2951070/page52 . They had such bt file missing with Moto G and ripped it from stock fw. I can't check if it helps placing that file into our filesystem. But you can. ))
PS: I wrote mickybart a pm about our issues, but there's no reply...

@azteched: Good to see that also others are struggling for a solution. I also found the thread mentioned by you. But I am missing the ble_stack.conf file. They are missing it in the mentioned thread too, but only bt_stack.conf is provided there. And I tried to reach mickybart too, but I never got any answer.
Hi, I will redo some tests with an headset that I know it was working. I will check if this is not an introduced bug. If I have the issue that will help me but if I haven't it will not be easy to fix it without an headset. In fact doesn't have the hardware is the main problem to be able to solve this kind of bug but I will try.

My fault. )) But AFAIK BLE stands for Bluetooth Low Energy, that is not supported by LT26i in hardware, so it doesn't seem to be the source of problem.
My girlfriend's headset is still working (Motorola H730). I will try to have an headset with the issue reported.

Hi wewa00, can you redo the same test but with a grep on "Audio|snd" and post the logcat report. If you prefer you can post a complete logcat and I will extract what I need.
Thanks

Here is the logcat: https://gist.githubusercontent.com/anonymous/857bd9914999d69a7ed6/raw/gistfile1.txt
I hope it helps. If not, please let me know.
Each time I use Mi6 via bluetooth in car to answer/make calls - first call goes OK, and all others not - people I talk to don't hear me. It happena in 4 different cars so it's not car's problem. Mi5 was OK. I run 7.1.1 NMF26X global beta. miui 8 7.6.8 global beta. And can't solve it myself. Tried deleting and re-adding cars, restarted phone - nothing helped. When I switch to phone during call - it's OK. As soon as I switch back to car - same problem. No one hears me and I hear everyone.
Any1?
I'm sorry but I can't test because I don't have any Bluetooth devices.
Not using any bluetooth device either.
Hello there
I'm a new xiaomi mi6 user. I have 7.5.25 version rom installed on my phone. My phone does not see andriod wear app on my smart clock with bluetooth. Also does not share internet with hotspot. There is also a problem with the GPS, the satellites can not find it immediately. can you help me.
Thank you

Ok, one by one.
1. My phone does not see andriod wear app on my smart clock with bluetooth --> My watch works, did you unpair your watch with old phone first? Android wear watch can only connect to 1 phone.
2. There's personal hotspot, you can see it in the settings menu.
3. GPS needs time to find your phone, you need to have wifi (or mobile data connection to assist the phone), if it located your phone, next time GPS will work faster.
It is a different issue with me: when paired with a BT device with the "phone audio" profile enabled, despite picking up the call on via pressing the green button on the touchscreen, it still defaults to the BT device (and I have to switch audio back to "phone" before the other person cuts off after hearing nothing). This is on the global ROM 8.2.2.0...
The global ROM seems buggy as hell...

Hello Friend.
The same happens to me.
It connects to bluetooth but I have no output or audio input.
Did you get it fixed?
Thank you
Everyone.
This is not xiaomi's problem.
This problem is due to oreo's new bluetooth stack.
There is no current solution to this. I've searched far, wide and deep.
Android has a great track record in keeping the bluetooth stack broken.
If you try to search google, you will find out that not only xiaomi phones have this problem.
The only theoretical solution is to port old bluetooth blobs, and somehow make it work. But as far as i know, no one has done this before.
There is hope that android pie will fix this. But from what i read, early builds of pie still has this problem.
Hi all,
like many 5T users I bothered problems with bluetooth connection in car audio system (spotify and calling). I've tried everything what I found on forums (downgrading software, clearing cache, energy settings etc.) but with no success. Finally I red somewhere that problem is OOS itself and custom rom should do the work. My question is: what custom rom should I use (on my earlier phone (samsung note 3) I used Ressurection ones)? Did someone tried this way and could tell about results?
Im on cnp and everything seems fine when I connect to my truck.
Thank You for fast reply, but did You experience bt problems on car audio system earlier (with official oos)? And what is cnp?

Codename Phoenix rom
What problems? I've been running oos all long and no issues with my car bt.
Problems with bt connectivity (spotify does not work - stuttering and disconnects and calling also). On official forum it's a popular problem and has many potentially solution. None works for me so far.
Many problems with my car BT (mercedes w211) with TugaPower ROM (now on v26.0)
After the initial connection car reports no (mobile) signal but I can manually dial. Automatic / voice dialing does not work.
Almost on every call BT disconnects and I have to redial. I make the call and few seconds into it, it drops call back to the phone with the car radio reporting "waiting for BT connection"
I tried to look into the logcat but I see no related error(s).
I'm also looking for a good rom that works with my car BT.
Hi Mi Max 3 Users,
Would someone be kind enough to check and confirm if you can use your bluetooth headsets with microphones on WhatsApp calls on the Mi Max 3 Phone.
I read a user's review that the microphone on your Bluetooth headset WILL NOT work (as in the user on the other end of the line will not hear you) when making WhatsApp Calls on this phone. The user says the Bluetooth microphone and headset works normally and as it should when making regular phone calls but DOES NOT work with Skype, WhatsApp, Facebook and other messaging apps. User claims that handset was tested at a Xiaomi store and they said that this feature wasn't supported on the phone.
Is someone kind enough to confirm this please.
I intend to buy this phone rather than the Redmi Note 5 and the phone being able to support the use of Bluetooth headsets with microphone and the mic on them for WhatsApp calls is a crucial element in my decision process. Everything else seem ok (unless you guys have noticed other problems in daily use).
Thanks in advance for your help.
It works just fine. I'm on Eu rom 8.8.9 non ARB; using with and without Bluetooth (apple airpods) in whatsapp calls and video work flawlessly for me. I use it all the time even with Viper4android enabled and disabled.
Thanks. Placed an order for one and arriving soon.
Hope running a global rom gives no different a result to your experience.

I answered already in your other post. It works just fine.
maybe that guy has a buggy ROM? for me - everything works great, since global stable MIUI 9.6.7.0, and newer versions as global stable 10.0.1.0, global dev 8.11.5, 8.11.8, 8.11.15. so I recommend you to buy this phone) I hope I helped
Thanks. Yes you did. Yes also, the pone seem fantastic and already placed an order for one.
