Ubuntu 20.04 Bluetooth "Connection to the device failed"

  • 772

This is to my bluetooth headphone.

screen1

Then I click on "Connect", and after a few seconds, I get this message:

screen2

"Connection to the device failed"

The strange thing is, this has worked previously. There might have been updates in between but I'm not exactly sure.

Also, I was dual booting Windows before, and there Bluetooth with the same headphone works just fine. I recheck by booting in again to Windows, and it still works, but then booting back to Linux, and it does not work.

This sounds related, because some people also report dual boots with Windows. However, the suggestion with reloading btusb (or maybe also btintel) did not help.

I had some previous issues with wifi + dual booting with Windows before. I did sth and it solved it, but I forgot what I was. I remember that to permanently get rid of this, I was supposed to disable the Windows "Fast Boot" feature. But there was another workaround to make it working. Related questions here or here, but I had found some other question/website with more information, but I don't find it anymore.

Anyway, I disabled the "Fast Boot" feature in Windows, and the wifi is working all the time. I did not had any issues anymore.

  1. After a bit of digging I was able to sove this issue for myself which involved connecting a bluetooth audio device. For me it was specifically a JBL Charge4.

    The solution was to install the pulseaudio Bluetooth module and restart it:

    sudo apt install pulseaudio-module-bluetooth
pulseaudio -k
pulseaudio --start

    Then when I try to pair I no longer get the message and it works.
