@muskist thank you anyway. Hopefully it'll be working when 20.04 will be relesed.

@yougo OTA-24 contains the same bluetooth stack as OTA-23. That was the object of the decision to revert.

The best thing would be having a working wifi with the stable: with taht version, the bt worked perfectly.

@bielsnohr

Just checked on my OP6 with OTA-22:
I am able to connect to Bluetooth headphones (MusicMan BT-X42) and listen to music.
Make sure that in

/etc/bluetooth/main.conf

the last line says:

AutoEnable=true

About bluetoothctl, its sometimes a bitch, but you can try:

sudo bluetoothctl

then you get a inside the terminal something like:

[bluetooth]#

there you enter, always followed by an 'enter':

power on agent on default-agent scan on

wait a moment... until you see $yourheadphones device.
You first need to trust your headphones:

trust $yourheadphones

then when its trusted, you should be able to pair:

pair $yourheadphones

and finally connect:

connect $yourheadphones

Not sure if you have to turn scan off or not:

scan off

Hope that helped... I did not test this procedure on my phone, but on a rpi 😉

@keneda There were two of them in there and I tried them both.

Then I decided to uninstall both of them I try them out one at a time. I quickly got it working after it failed the first time. It kinda seems slow to me, at the moment but I'll keep trying them out.

Thanks Keneda

Finally, I made a reset factory.
Miracle, all work !!!

@crab_aesthetics First I thank you for the process you showed in your install. It is a good road map. I will be trying a similar install as soon as I get my replacement phone. I will be using a Linux laptop and my cellular provider is Visible by Verizon.

@keneda said in How to stop and restart Bluetooth service?:

some bugs on MX4 unfortunatly

Sorry to hear that! On OpO, it's pretty much flawless. It really helped me when switching from Android... I felt a lot more at home (sorry, devs). And I like having an analog clock on the home screen.

@Moem Oh! I forgot! Sorry!

@applee Good idea. ✔️

If you mean with this app :
https://open-store.io/app/ubtd.fourloop2002

Files copied to your device are held in ./.cache/ubtd.fourloop2002

@isolated-thinker probably no one replied to your question because nobody knows the answer 🙂

The only thing I can tell you is that there are a lot of issues with bluetooth in UT, as you can see in "The" Bluetooth Thread.

@pierref you're welcome. I'm glad you found a solution!

@altr0n Looking at this: https://github.com/ubports/android_kernel_lge_hammerhead/blob/ubp-5.1/arch/arm/configs/cyanogenmod_hammerhead_defconfig#L1491
bcmdhd is being built as a module. Can you confirm that it is being built? Maybe it's just not being installed. How exactly did you "craft" the boot image?

Hallo,

Microphoneunterstützung ist in RockWork leider nicht implementiert...

Cesar,

Now that you're able to get an error msg I strongly suggest to look on google : https://encrypted.google.com/search?hl=en&q=Failed to pair%3A org.bluez.Error.AuthenticationFailed

You're problem might be linked to a driver bug, but i doubt is linked to ubuntu touch itself, even ubuntu.
Good luck
