        @nreal Can u try this in the terminal

        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.

          @nauvpp I think it is driver issue.

            @nreal This will work for me :

            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.

              @nauvpp hello nauvpp, i followed your advice and used fastboot flash bluetooth_a bluetooth.img on my mi a2 , but it was not effective. 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?

                This is what i get as a result from the terminal when trying to get infos about bluetooth. Can you check if it has the same stats as yours?!

                  @bogotrax another output. I hope this helps even though i am not sure it is suppose to look like this. I expected a clearer firmware description.

                      I typed this: fastboot flash bluetooth bluetooth.img

                      It comes this:
                      target reported max download size of 536870912 bytes
                      sending 'bluetooth' (556 KB)...
                      OKAY [ 0.031s]
                      writing 'bluetooth'...
                      OKAY [ 0.010s]
                      finished. total time: 0.042s

                      But it did not work.
                      What I made wrong ?
