Hi RH,
at least to my knowledge there is no other reliable solution except of unplugging in replugging the OBD dongle. But what I found out that often seems to work instead of this, is selecting any arbitrary different bluetooth device for connection in the list of known bluetooth devices in the phone/the OBD settings menue. This will force DMD2 to try to connect to something it does not understand. If you select after this unsuccessful connection attempt the OBD dongle in the list again, it often connects without the need to un- and replug the dongle. Just give it a try.
Hopefully in some time John will find a solution for the DMD code that this becomes unnecessary.
Hope it helps!
