I am facing a Bluetooth problem in ubuntu 20.04. When I ON my HP Notebook, it works properly but after some time of disconnecting or not trying to connect, it goes off permanently and needs to reboot the computer. Then it works properly but if I want to connect any Bluetooth device after some time, it doesn't ON. The laptop is Dual boot: Primary OS: Windows 10 and secondary: Ubuntu 20.04. I have tried the following methods:

$ sudo service bluetooth restart
$ rfkill unblock bluetooth

Is there any method to fix it or it is the problem in this ubuntu version?

  • On your terminal write sudo btmon, then use it as you are using now, and then post the output here. – Mr. Panda Nov 22 '21 at 12:47

Have the same problem on a HP desktop. Tried all kinds of bluez, blueman stack exchange wisdom, but the thing that always works is to power cycle (sometimes restart works). Same on Ubuntu 20 and 22.
