I just tried to use my phone (Samsung Galaxy S4, Android 5.0.1) for flying the Larix copter. The app installed without problems.

When I switch on the copter, I see a bluetooth-device named "RNBT-D13D" or "RNBT-CEFF", which is probably just some generic name of the BT-module. The app obviously wants something called "XMC-Bluetooth".

Do I have to make some special settings in cleanflight? Or more generally, are there some written guidelines on getting the control via bluetooth to work?

A while ago I flew the flyingPCB (pre-cleanflight) using the phone, which worked fine. Has the bluetooth-code actually been ported to cleanflight or do I need another special version?
