Bluetooth settings in Developer Options - Huawei Mate 10 Questions & Answers

Hi, can anyone change the Bluetooth Audio settings and they actually change ?
i.e. if I select aptX as the Audio Codec it still shows as SBC on the Menu. This is the case for all of the Bluetooth Audio selections - Sample Rate/Bits Per Sample etc - nothing actually changes.
What am I doing wrong ? Mate 10 (Not Pro)
Cheers

Would like to know the same. /buyp

Got same issue only SBC in streaming Bluetooth... Please somebody can answer!! It's pretty boring...

It's an automatic process, if you bought audio equipment with the different codecs, it automatically chooses the correct one. Connect a device with the apt X and you will see it automatically change.

EMUI doesn't support AAC, if your headphones doesn't support LDAC or Aptx you are stuck with SBC.
SBC is kind of problematic as of right now.

Maybe someone can help me, i updated last week my phone. to 137. (ota) i reseted my phone to get a fresh rom
about a hour ago i was in my car , and my radio dosnt show titels anymore and i cant forward tracks via radio. only on my phone.
My radio says "BT AUDIO" and its just playing. not more. .... that kinda sucks on the version before it was all okey.
Yes i delted car and phone bluetooth and reconnect. same issue.

Bluetooth stereo audio

Hi everyone,
Here is my challange:
I only use bluetooth with my carstereo (kenwood KDC-BT60U).
Everything works perfect, handsfree calling pairing ect. Now here is my problem, I like the BT stereo audio so I can play music from my LEO over my carstereo. BUT I cant get that function to autoconnect everytime I want to use it I have to go true all the menue's to turn it on in my phone. I have searched the reg but as a noob I cant find it.
I hope anyone has the answer to get it working like I want it to. (I have spent hours puzzeling)
P.S. I am on Artimis 22.0B Radio 2.12

Hi Jimi,
I'm starting to think that this is the case with most, if not all head units. I had, until recently, an In Phase IPS247BT head unit and that did exactly the same: automatically connects to the phone's handsfree, but I need to manually connect the stereo audio. I contacted the manufacturer and they said they designed it this way to save battery life on the phone. Some searching around on the internet shows that this is a common issue. On XDA, I found this application which runs in the background on your phone and automatically connects the Bluetooth streaming which it detects the handsfree is connected, but unfortunately, it only works on phones with the Microsoft Bluetooth stack and our HD2s have the Widcomm one. I have been looking into writing a similar program myself for the HD2, but don’t hold your breath over that.
Incidentally, I have been considering purchasing the KDC-BT60U myself – it looks like a nice head unit. However, in the Bluetooth compatibility charts on Kenwood’s website, they state that the head unit cannot automatically connect to the HD2s handsfree and that you need to do that yourself from the phone. Admittedly, they tested this on a 1.43 ROM whereas I’m using the latest 1.66 ROM. What has your experience been?

Hey amrbekhit,
I never had that the handsfree didn't connect automatically, as soon as I got my phone I flashed artimis so I dont know what it will be like with a 1.66 rom.
My personal guess is that it will work.
My neighbour has the same phone but its still stock and he has no problem with his pioneer unit.
I am not a programmer but a toggle would be a nice as a second option to activate the BT audio, I'll search for it when I have the time and post my findings here.
One thing that's weird is when you pair the phone for the first time the stereo also autoconnects but after that it almost never happens again...
thanks for your reply,
Jimi
I've just fitted a Kenwood KIV-BT900 to my car and started using BT for the 1st time. I've paired my HD2 with the headunit without any problems for the handsfree side of things but when connected, there's supposed to be an option for BT Audio in the headunit's menu but this never appears and I've no idea how to get any further.
Handsfree calling works fine, HD2 & KIV pair automatically when the KIV powers up.

Hi Major_Sarcasm,
In my Kenwood the option to connect BT audio is in the Phone selection menu
Press the horn, go to Phone selection press "enter", there I have something like choose Phone and beneath that I have select BT audio.
Not sure if the same menu is in your device.
I also can connect from the phone: go to settings (on the far right of sence), press the soft key menu than more and than you can choose BT, than go to go to your paired kenwood and press the "+". From there you can select Stereo Audio and it will connect.
P.S. did you check your supported connections? (*maybe you forgot to check the stereo audio).
Good luck, Jimi
Sounds like my Kenwood is slightly different as the BT Audio option is supposed to appear with all the other sources. Also, there is no Audio option on the phone's BT settings, only the HF. I'm not gonna let it worry me, the important bit works, it just irks me slightly that BT Audio is supposed to be there as an option and isn't...
Thanks for your reply though.

Bluetooth Codec problem

Hello,
Just bought a P20 Light and a pair of Pioneer Headphones SE-MJ553BT-K, the headphones support AAC codec but when I try to change the codec type from developer settings it jumps straight back to SBC.
The audio quality is by far better with the same headphones when using a iPhone and a Smart TV,
Does anyone know how I can change the output codec, an app or something else.
Thank you!
Got a response from Huawei România.
They said that they were abble to replicate the problem but they need more time to understand we're the problem is starting and time to fix it.
A update will be issued at a later time, but no time table mentioned.
I bought a new pair of Bluetooth headphones (MPOW Judge) and no have the same issues. I wanted to blame the headphones first, but on other devices they sound great. It's too bad ...
I have the same problem with P20 lite. My BeatsX sounds just AWESOME on iPhone of ANY model. Even on iPhone 5S they sound billion times better than on Huawei P20 lite. I am not able to change the codec. It is awful. Just awful. If you have a good headphones and want to enjoy the music - better to seek for some other smartphone brand.
If anyone knows any app or something to change the bluetooth codec PLEASE tell guys!
see my post here for a similar issue that I was able to workaround fairly easy
TLDR: You need root, edit your build.prop (using text editor, some app from the play store, etc) and change the following key: persist.vendor.bt.a2dp_offload_cap
by removing -aac from the string.

Bluetooth Media Browsing

Hey guys,
I got my Redmi Note 5 today and went out for a drive. Unfortunately, I have not been able to use the media browsing feature with my car's entertainment system. I even activated AVRCP 1.6 in the developer options, but to no avail.
Has any of you guys been able to use media browsing via bluetooth? Help would be much appreciated.
Cheers.
Have the same problem.
You van change in developer options the audio bluetooth codec to SBC.
By me this works. But problem is that it does not Stay on this setting.

Hey,
thanks for replying. So you're saying that changing the audio codec to SBC lets you browse through your music library via bluetooth? Afaik, codes don't affect media handling like that.
No you are right.
With me the problem was that i could not get any sound from my phone to the radio. So it is not the same problem.

Poor bluetooth audio quality

Hey guys,
I have connected my A3 to a roidmi in my car and i have noticed there's a very poor audio quality over a blurtooth. I have also checked it with a stereo in my living room. Does anyone else got a same problem? How to get over it?

Ya i do have this problem, its a bug that hasn't been fixed yet. Turn volume down by 3 steps and you will be fine.
just enable developer options and set it to the highest quality, by default it is using the lowest bandwidth with the lowest quality
There is an even more serious bug with this phone and Bluetooth : if you get a call while streaming audio to a Bluetooth headset, music stops as expected, but then playback fails after the call has been ended. You need to reboot in most cases in order to get back music playback.
Tested with several Jabra and Plantronics headsets and different music players.

Are you sure it's actually doing this? Because when I switch Bluetooth to using another codec or higher quality, then hit back button, then go back into dev options, all the settings are back to default, so I don't think it actually does anything. I have a Bose qc 35, which is supposed to support aac.

Try this Magisk module and increase the bitrate of SBC codec. You might need to experiment a little to find the best value for your setup. Start at the max (or just use the recommended value) and gradually decrease until it's stable. High bit rate SBC can have higher quality than APT-X (HD) - you will need to disable "HD Audio" in Bluetooth device setting to force usage of SBC.
I was using it with Mi A1, but haven't tried with A3 yet.

Btw. changing BT codec in developer settings never worked for me, not sure what's the purpose of it
Same problem for me. My bluetooth headset sucks at this device. I hope we can find an easy solution immediately

Its not the bitrate, it happened with me many times before so i can tell, phone boosts the volume past max for some reason which causes distortion, reducing volume fixes the issue

I'm trying this module. I turned on Bluetooth snoop logging to see if I can see what bitrate I'm actually getting connected with. There is text .log file enough which is only few bytes and a larger binary file with
cfa extension. You don't happen to know what format this is, do you?

CFA is a binary btsnoop file containing all the packets related to BT connection. It should be possible to open it on a PC in Wireshark. I couldn't find a way to open it on Android directly.

In my case (JBL Free X), this is not an solution, it's only quite better, when i set bitrate higher than 574
I think I have found solution for this problem. I have installed miui 11 on my mi a3. Then I have installed magisk and gjf_bt module. Noises no more. For some reason this module doesn't works on stock rom

I have the same problem... after a factory reset it worked for a week ... now the problem returned ... did anyone find a solution?

Aptx HD?

Our phone was announced to be capable of aptx and aptx HD. I own two different bluetooth receivers with aptx HD enabled. But when I connect the phone to them, it uses only aptx, as the connection info on our device and the LEDs on the receivers reveal. This behaviour did not change from Android 9 to 10.
My wife has a Mi A2, and with this device aptx HD works on both devices under Android 9 and 10. Is there a hidden way to activate aptx HD on our phone? Meanwhile I think our phone is heavily neglected by Xiaomi because such features present in a Mi A2 mysteriously vanished.

It's on developer settings.
Also, if forcing aptx HD is not working or has bugs, remember to report it.
This was the first thing I tried, but predictably switching to aptx HD in developer settings has no effect (I wonder what use these settings have - I never heard that someone succeeded in activating codes this way which his phone didn't choose automatically).
Update: I changed to crdroid 6.6 - and now aptx HD works flawlessly.
Hi sir, today I've got issue with connection to Fii0 BTR3K - no sound from PowerAmp which I was using for weeks without problems before. I did security update from May yesterday (yep late a bit) and got this issue. Fortunatelly to me I have SBH50 from Sony to test everything on low profile SBC connection. Lucky to me, I did another update to August security patch for Android 10 today.
Now I have Aptx LL ([email protected]) working with BTR3K (purple indication on LED). What I learned from today: Do not touch Dev settings! By misstake Dev settings could store your input as wrong data in 'system default' for application (PowerAmp in my case) and lead to missfunction. In my case PowerAmp was reading [email protected] even from non-aptX device. Second: actual condition of connection could be changed during SW initialization. So test your player SW and try to reset it as I did.
For specified [email protected] I am using Hi-Res output of PA. I am pretty sure in numbers as I can hear the difference between SBC and aptX, and hear difference with 16 to 24 bit resolution change (by enabling\disabling tone processing in ounput pipeline). To enable 24 bit in PA you should disable \reset to default dithering method.
I think AptX-HD isn't fully supported by 2 reasons: no real benefits over LL profile + licensing catch.
Hope you will learn something from my evidence
I have haylou gt1 plus earbuds. Apart from bad connection , the buds are aptx-HD compatible, one of their selling points. When i go to developer settings to check, aptx is used. When I change it to HD, it detects the change, nothing happens, and when I go back, and enter dev settings again, it is still on aptx . I think that's time to throw it in the sea... it's already blue
Sapper Morton said:
Your earphone doesn't support AptX-HD, that's why when your manually change to it using Developer Options, the codec isn't selected; use AptX or AAC, as advertised by Haylou.

It's weird cause all reviews I read, specifically said aptx-HD, but you are right. It's only aptx. Nevermind. My mistake !
