Bluetooth firmware fails to load with latest snapshot 2024228

English Applications

From an old boot after installing that snapshot:

sudo journalctl -k -b-3 | grep firmware

Feb 29 16:44:42 andromeda kernel: Bluetooth: hci0: Failed to load firmware file (-2)
Feb 29 16:44:42 andromeda kernel: Bluetooth: hci0: Failed to set up firmware (-2)

Consequence: Bluetooth completely unusable. KDE says it’s disabled, clicking the “Enable” button is of course ineffective.

I’ve rolled back and it’s fine again.

Offending package is one of these, any ideas? Thanks!

I’m finding the same thing in multiple rolling releases. Until it is fixed, I have found that I can install blueman from the repo. I open blueman and connect the bluetooth with my peripheral. Works just fine. Then , once the connection is completed, I delete blueman. From then on Gnome bluetooth works fine.

Thanks, but this didn’t work for me.

The issue is with the loading of the firmware, so I suppose that no tool in user space can fix that.

Actually I just noticed that my initial post is missing a crucial line:

Mar 04 12:34:45 andromeda kernel: bluetooth hci0: Direct firmware load for mediatek/BT_RAM_CODE_MT7922_1_1_hdr.bin failed with error -2
Mar 04 12:34:45 andromeda kernel: Bluetooth: hci0: Failed to load firmware file (-2)

Does this file exist under /lib/firmware?

Here’s what I have in that folder (notice the .xz extension):
