I have just replaced my Realtek M.2 Wi-Fi + Bluetooth card with another M.2 module based on the Mediatek MT7922 chip.
The Wi-Fi works correctly. However, bluetooth does not. The dmesg output shows that it fails to start/initialize(?) (code -110).
The device possiblyappears in lsbusb as Bus 001 Device 007: ID 13d3:3625 IMC Networks Wireless_Device, but there's not clear indication of it being a Mediatek product.
I have already tried /found the following solutions:
- https://github.com/mohdsami91/MediaTek- … oth_fix.sh (removed the apt-based parts, everything else worked fine, but still no bluetooth)
- hard turn-off the pc, multiple shutdowns and power unplug, as suggested in various posts, bluetooth never comes up
- installed linux-firmware-mediatek
- found some posts about patching the kernel, mostly old versions and broken links, could not follow any...
- this https://github.com/bluez/bluez/issues/995 seems to be the same issue, but it's marked as solved and I clearly still have it - not sure if itwas simply unrelated...
Can someone please help me with this issue?
