Hello, last night I was trying to test out my lr1000 sbus rx with an old cc board (bl4 / 16.09) and was getting "no activity" on the transmitter setup. Rx bound fine and I was receiving telemetry on my taranis.

Tried hooking up another sbus rx and it worked as normal.

Switched the flexiport to dsm and plugged the lr1000 in there and was getting erratic activity on all channels so the rx is def. send out a signal to the fc.

Any suggestions?
