After some time, the communiation gets stuck and I have to restart bluetoothd. Any ideas how to fix this?

looks like following command fixes the error too: echo "disconnect B7:1E:5A:99:BF:21" | bluetoothctl

Hi Daniel, I have the same issue, so I tried your suggestion and it doesn't really help on my setup :( I just wanted to let you know. Thanks for sharing!

@Benjalien , I switched to this fork and it works without problems: https://github.com/xrucka/cometblue
