Bluetooth not working after update, got this:

[bluetoothctl]> power on
No default controller available
[bluetoothctl]>

Any ideas folks? Was all working before this. Have tried the applet and system settings and bluetooth cannot be enabled

also got this:

bluetooth.service - Bluetooth service

The next comments explain that Mediatek chips are affected. Do you have one?

I do.

Good to know there’s a diagnosed reason.

I have rolled back to 7.0.6-1 kernel till then new kernel with fix comes out. If you have btrfs snapshot you can easily select this kernel during boot menu.

This happens to me very often.

run “sudo rfkill” <------ install if not installed

Look for bluetooth blocked. For me it is always blocked when bluetooth is not working. I am trying to fine out what blocks bluetooth but no info thusfar.

run “sudo rfkill unblock bluetooth”

rerun “sudo rfkill” to see that is is unblocked.

reboot – “sudo reboot”

Look at bluetooth icon in panel to see that it does not have a red (x).

Play some audio like youtube. Turn off your bluetooth, e.g., with the headphones on/off button. . Restart device, e.g., headphones with on/off button. On headphones you will hear “connected” two times.

After that bluetooth is running.

No, this thread is about a specific issue with Mediatek cards.
BTW a fix should be in snapshot 20260520 that is just hitting the mirrors while I am writing.

It’s not fixed in the latest snapshot with kernel:7.0.9-1

15

Ya, I don’t think the back ported fix made it into the released kernel. At least from the kernels bug tracker it looks like the needed fix is in 7.0.10.

16

Indeed, 7.0.9-1 did not fix the issue. Now hope soon to receive the kernel with the fix.

I was having this issue while on the long-term kernel. Update last night fixed it for me!

Latest update of kernel 7.0.10-2 has rehabilitated the Bluetooth - now working.
