Even though we don't officially support it, the Ghost system has been able to emit the CRSF protocol from the receivers from some time now.
To enable this 'hidden' mode, enter the 'BahBahNami' code on the JR/Lite module joystick:
Press, Up, Down, Left, Right, Up, Down, Left, Right, Press
The module will play the first few notes of a well known nursery rhyme and reboot. At this point, the CRSF protocol will appear in the list of Rx protocols available during binding.
