ADDITIONAL INFORMATION

In Bug 459585, you've reported that sometimes Bluetooth is not being enabled on login.

Is this problem happening on the logins when Bluetooth *is* enabled automatically as you would expect?

It's not a kde problem. It'd zdruver problem.

Comment 3 Philippe ROUBACH 2022-09-27 09:14:56 UTC 
It's not a problem with chipset intel AX210 (Bluetooth 5.3).

I think it is useful for debugger to know this.

There is no problem between a Bluetooth 5.0 tablet (Blackview Tab 8) and a PC equipped with Bluetooth 5.3.

There is problem between a Bluetooth 4.2 smartphone (Samsung S7) and a PC equipped with Bluetooth 5.3. You can't connect the smartphone from the PC. You can only connect the PC from the smarphone then immediately disconnect/reconnect the smartphone from the PC to get all the protocols HSP and A2DP.
