<![CDATA[Unable to turn on bluetooth on Mi A2]]>Hello all,
yesterday I managed to successfully install the UT (OTA-19) on my Xiaomi Mi A2. Everything works well apart from bluetooth.
After boot, the bluetooth is activated in the system tray, but when go to the bluetooth settings to search for devices, the bluetooth is off and the phone is undiscoverable. And it cannot be switched on at all.
Sometimes it helps when I disable the bluetooth in the system tray right after reboot, go to settings and enable it there. But not always. I cannot find any particular pattern how to make it work reliably.
Another thing is that even if I am lucky sometimes, I manage to activate the bluetooth and connect to any audio device (headphones, car multimedia), the sound is played through the bluettoth device in all cases except from the phone call. If I make a call, then its sound does not go through the bluettoth, but through speaker of the phone (dialing via bluetooth works well).
Does anybody have similar experience or does anybody happen to know how to fix it and make bluetooth work reliably?
Thank you.

It comes this:

I used the latest firmware from firmwareupdater site for xiaomi devices V11.0.28.0.QDIMIXIM . i extracted the bluetooth image and flashed it with the img. Can you confirm that these are the steps to take? Is there anything you did differently? Thanks in advance! Is there a way to read out the firmware version for bluetooth of my device somehow?

  1. Download firmware_jasmine_sprout_V11.0.28.0.zip
  2. flash file "bluetooth.img" to slot a or slot b (depends of the setup)

This fixed completely BT issue on my MiA2.

Bluetoothctl [enter]
scan on [enter]

Then u should get this message:
No default controller available

I'm trying to get BT stops then starts again with command line but no success yet.

sudo service bluetooth restart

Does not gives any positive result neither

  • on MiA2 = nothing happens + unable to restart the phone, need hard power off.
    It seems that a process is really stuck.
  • or PRO5 = "job has already been stopped" but BT is still on

Would be interesting to ask someone owning another halium 9 device.

  1. Activate WIFI
  2. Activate BT
  3. Restart the device

Step 3 has to be quick before BT switches off again.
I've tried multiple times and it's ok for me.

WIFI is on and BT is on = OK, can see devices. BT off then on again = OK, can see devices.
Set WIFI off = BT goes OFF itself few seconds after WIFI.

Set WIFI back on = BT stays off.
Restart is needed to get BT back on too.
If you can repoduce, I will file a bug.

I've recently noticed that BT if not working anymore if you switch off WIFI. Switching back on Wfi + A device restart is needed to have BT working again, or maybe at least a netword service restart with command line.
