Bluetooth doesn't work on AX200

This is on Kernel 6.1 but this actually started a while back on 5.15.

The System Settings GUI says “Bluetooth is disabled” and there’s an “Enable” button that does nothing. I can’t pair new devices. But, I’ve had KDE Connect linking my phone & desktop since I was using 5.4.

It still works I can send files over KDE Connect no problem. At no point did it stop working. Clearly bluetooth is working to some degree. I don’t understand it, and I’m still to green to know where to start fixing this in bash.

Any ideas?

Can you provide system information and report the result of the following command please?

systemctl status bluetooth

KDE connect uses the local network by default, not Bluetooth.

Sorry, I edited it. Let me know if there are any other problems.

Does anyone know how I might fix this issue?

Sorry, it seems this thread slipped my notice. What about the output of the following?

Some research suggests that this is a bug in the kernel affecting various bluetooth cards, including yours (AX200), for Kernels 5.15+

https://bugzilla.kernel.org/show_bug.cgi?id=215167

What happens if you try 5.10?

That fixed it! I was on 6.2 before switching to 5.10.

What, if anything, does this mean for newer kernel versions? Is this a bug that’s libel to get taken care of eventually, or is this a case of hardware being so prickly or unsupported that it’s going to be an ongoing problem?

You can periodically check other/newer kernels … possibly in connection with some configuration or extra package(s) … until then you will miss out on some of the new ‘shiny’ things in more recent kernel releases … but that rarely matters for much if you dont have newer hardware.
And for some peace of mind … 5.10 should be alive for some time still … with a projected EOL (end-of-life) set at December 2026.

Some commenters on the issue claimed to have solved it with a minor patch. If you’re down to compile your own kernel, you could try applying it now. In theory, this should mean that it can be solved in the future. However, I don’t know enough about kernel development to say what will happen.

If you make an account on bugzilla.kernel.org you should be able to add yourself to the CC list to stay updated on what happens.
