Hi,

 

I updated my system to version 5.20.

This version is supposed to solve the problem of bluetooth.But this is not the case.

Can you help me?

 

thanks.

Probably something is missing, a script for loading Bluetooth firmware, firmware or Bluetooth stack. Try with clean image - it should work out of the box.

Ok I tested.

 

bluethoot ok.

 

but the function I want to use, loudspeaker emulator, does not work properly. the sound is constantly cut, choppy.

 

it's not an armbian problem...
