Lift dis- and connect out from config operations

When working with ostc's via bluetooth, they will reboot and exit
bluetooth mode when you send the disconnect command. Thats kinda
inconvenient when you would like to read your settings, change something
and write it back, you need to start bluetooth mode on your device
twice.
