Bluetooth not working | mt7921e

So my Bluetooth was working fine just a few days ago but all of a sudden the Bluetooth option seems to have disappeared from the quick settings menu and when I go to Bluetooth settings it just says “No Bluetooth Found”. The only noteworthy change I remember is that there was recently a firmware update that was automatically installed on my device by GNOME Software, but I’m not sure if that’s what caused the bluetooth issue since I didn’t immediately check if Bluetooth worked after that update.

I use Fedora 37 on an ASUS ROG Zephyrus G15 (2022) laptop. The model number is GA503RM. I tried looking for what bluetooth adapter my laptop has but searching on the internet didn’t really give me any useful results.

I tried doing the following steps:

sudo modprobe -r btusb
sudo modprobe btusb
sudo systemctl restart bluetooth

but they didn’t really end up accomplishing anything.

Here are the results of some commands that might be useful:
dmesg | grep -i blue:

[  951.326722] Bluetooth: Core ver 2.22
[  951.326748] NET: Registered PF_BLUETOOTH protocol family
[  951.326749] Bluetooth: HCI device and connection manager initialized
[  951.326752] Bluetooth: HCI socket layer initialized
[  951.326754] Bluetooth: L2CAP socket layer initialized
[  951.326758] Bluetooth: SCO socket layer initialized
[  958.094363] Bluetooth: BNEP (Ethernet Emulation) ver 1.3
[  958.094365] Bluetooth: BNEP filters: protocol multicast
[  958.094368] Bluetooth: BNEP socket layer initialized

sudo lsusb | grep -i bluetooth outputs nothing.

inxi --bluetooth:

Bluetooth:
  Message: No bluetooth data found.

bluetoothctl show:

rfkill list all:

	Soft blocked: no
	Hard blocked: no

nmcli radio all:

Thanks for the help in advance.

The problem seems to have magically fixed itself after a restart

With the change of kernel versions, drivers have to be adapted. Your Bluetooth might be integrated with your network card.

Lets check again with inxi -EN to see what it shows now (Bluetooth & Netwok). For the next Kernel Update.
We do have a lot of requests because of Asus Boards/Laptops. Then I will update the title adding your hardware.

You made a very nice list of commands people can use to debug!

The problem seems to reoccur after updating to Fedora 38.

It looks like your WiFi adapter not has an update for F38 yet.

As a workaround you could try the LTS Kernel so you could at least use your system.

I don’t really need Bluetooth atm so I guess I’ll just wait until the update arrives.
