Ubuntu refuses to reconnect to my bluetooth device

Table of Contents

Context

I’ve already connected my XUbuntu 22.04 (LTS) laptop plenty of times to my Ultimate Ears Boom 2 wireless speaker.

All of a sudden, this morning, my laptop refuses to connect to my speaker without any obvious reason:

My wireless speaker was still listed in my Recent Connections and I wasn’t in a new device pairing situation.

Analysis

This step was quite quick but I still wan’t to log the messages that appeared in my laptop system logs:

Here were my system details when the problem occurs:

Quick and dirty solution

I didn’t spent too much time looking for the root cause of this problem.

My quick and dirty solution was to remove the device from the known device list using the U.I:

and then create a new pairing with my bluetooth speaker:

That’s it. Still not sure what went wrong here. Nevermind, my bluetooth speaker is now working as before and I’m ready to rock !
