Devo 7e *bayang protocol problem

Having issues with binding my
Beta fpv and e011 with my Devo 7e I’ve successfully flashed with nightly and 5.0 builds. When I select the bayang protocol there is an asterisk next to it and re-Init does nothing when pressed. Appreciate any help. Thanks

The asterisk means you don't have the necessary radio module installed. See the hardware section in the Getting Started link on the left. There's also a commercial module with all 4 radios and there are some posts in this forum about putting it in a devo 7e.
