Bluetooth suddenly stops working, failed condition check, stops loading kernel module

Hi,
Bluetooth has lately (since last week, same problem) been giving me a headache. It worked perfectly in EndeavourOS after fresh installation today, but after ~12 hours in middle of use it cut out the connection and could not reconnect to device.

Switching bluetooth off from blueman or bluetoothctl causes the device to disappear. Restarting bluetooth.service gives error regarding failed condition check. After fresh install was loading fine and automatically, now it has also disappeared. No new updates were installed prior to this. Kernel is 5.16.0-arch1-1
Edit: BT chip is Realtek PID_3530

Switching device on/off via bluetoothctl was working prior to this.

Loading btusb manually via modprobe and restarting bluetooth.service even when its active in status does not yield working BT in bluetoothctl.

Logs:

Trying to reboot after this resets situation back to the beginning with lsmod giving nothing and bluetooth.service failing to start due to failed condition check.

Cold boot sometimes fixes this magically.

Bluetooth has been tested working in different os and also in windows.

I’m completely running out of ideas :pensive:

Despite all of the system information provided there’s nothing about the Bluetooth adapter itself… :pensive:

If you just updated to 5.16 then it’s likely a regression. Try linux-lts to return to 5.15, and then try 5.16.1 when it comes out of [testing].

Thank you. I’ll try this and/or kernel 5.14.
I’ve had this problem occur with 5.16 and 5.13 for some reason.
Bluetooth chip is Realtek PID_3530.

This morning after hard reboot this fixed itself again magically :thinking: lsmod shows btusb, bluetooth.service is running perfectly and connection works.

I can’t find any reference to this anywhere on the web so I’m not convinced this is the correct device ID - you might look at inxi -Faz to get a list of system components.

Interesting, and possibly due to a conflict with the Windows driver:

I couldnt find anything with that PID_3530, but it is what both linux and windows has reported as device ID. Maybe combined chip with WiFi? Note: I do not have wifi enabled as I do not need it.

Currently I’m not running dualboot, tested with fresh windows installation to rule out possible hardware malfunction previously.

So far with lts kernel bluetooth has been working with only single hiccup which required bluetooth.service restart. Compared to last times service started normally after this and bluetooth resumed working. Previously stopping bluetooth.service or running reboot resulted in previously described problem

This time when bluetooth locked up while using bt device systemctrl gave this information:

Here’s the Bluetooth device and the actual device (chip) ID.

Now we know the device ID we can check, and yes, it is a combo module: https://wikidevi.wi-cat.ru/AzureWave_AW-CB295NF

Likely to be a regression in 5.16.0. 5.16.1 may be better, otherwise you can stick with 5.15 until the driver in 5.16 is fixed.

Thank you for your help. Since switching to 5.15 LTS kernel Bluetooth has been working.

So far so good. Lets hope it stays this way. Ill mark previous message suggesting 5.15 lts kernel as solution.
