problem in both cases: vm and real system. Same problem
I always connect only 1 bluetooth dongle. If i test the other dongle, i take out the previous and wait a moment for the needed scripts to catch up (dont know if this pause is needed).
I turned off bluetooth of my phone, as i first thought that was the problem, but that didn't change anything. I saw in another thread that i'm not the only one, but there wasn't a solution posted.
