Hi,

After upgrading my fedora 44 KDE edition the bluetooth is no longer working :frowning:

Any solution ?

Thank you

WiFi often has issues after upgrades, so I use a WiFi USB dongle while waiting for a solution.
You need to provide enough detail for us to understand the problem – e.g., enough detail to allow others with access to similar hardware and Fedora spin to reproduce the issue, e.g., the full output from inxi -Fzxx. Please include the output from rfkill. Note that WiFi problems can be due to outdated vendor firmware or conflicts with other installed OS’s. To make it easier to reproduce the problem and avoid wasting energy on a solved problem, ensure that you have fully updated Fedora and vendor firmware.

If you boot up in the previous kernel does your bluetooth work?

What is the last working kernel and which one broke bluetooth?

You should be able to compare the logs from the working kernel to the broken one and may see a difference that is important.

Extra Info about my system.

The wifi is working properly but only the bluetooth is not.

I will reboot. Last week the BT was OK and it’s broken after today’s update + reboot

So it’s working with 7.0.12-200.fc44.x86_64 but crashing with 7.0.12-201.fc44.x86_64.

I will stick with 7.0.12-200.fc44.x86_64 for now.

Thank you for the hint.

Maybe try a fwupdate to see if there’s an updated firmware for this device.
