Bluetooth Not Working - No default controller available - Intel AX200

I cannot get Bluetooth to work consistently on Fedora 40 KDE

It has very rarely worked with various restarts of computer, services, etc, but I haven’t found a stable formula.

In the current state, it shows as disabled in system settings, and clicking enable does nothing.

Using the bluetooth tool in the taskbar shows “No Adapters Available” in the tooltip, and I can still try to pair, but it won’t find any devices.

Also noticed this is the driver: ibt-20-1-3.sfi, but I do have a …1-4 in the same dir, but not sure if 1-4 is correct, nor how/if to change that

this says secure boot is enabled, but note that I dont have secure boot enabled in uefi.

TRIED:

  • various systemclt stop/start disable/enable
  • sudo modprobe -r btusb then sudo modprobe btusb
  • Bluetooth is on in uefi, not off or auto, Ive tried toggling this.

I dual boot, when I go back into windows Bt is broken, I have to disable the Bluetooth driver, then reenable in device manager to get it working, I believe this is basically to reset whatever linux is doing to get it into a state that is carrying over to windows somehow, haven’t done a ton of tests to confirm this is 100% repro though.

Note I’ve tried OpenSuse Tumbleweed KDE as well, and same issue.

I’m not seeing any errors that jump out as to why it can’t find that controller.

Hopefully this helps someone - I found arch linux - Bluetooth won't work: "hci0 Reading Intel version information failed" - Unix & Linux Stack Exchange which has a solution of sudo sh -c "modprobe -r btusb; sleep 2; modprobe btusb" and that seems to have fixed the issue for me

Make sure you disable fast boot windows startup
Using the Run dialog

Press the Windows Key + R to open the Run dialog
Type powercfg.cpl and hit Enter
In the Power Options window, click Choose what the power buttons do
Scroll down to Shutdown settings and uncheck the Turn on fast startup box
Click Save changes

After you do that shutdown windows and boot fedora try like that bt
