Re: Bluetooth not discover LE devices (Intel AX201)

It was fixed by using btmgmt. Just type le on and all works. But have another problem. Connection to my logi m590 can't stay after turn off mouse/turn off laptop. I can not reconnect to the mouse after disconnecting it. And btmgmt settings resets after reboot.
