Research direction
Start by reproducing the Speedybee VRX setup described in the issue, using the Happymodel EP2 firmware and the VTX Admin Lua interaction shown in the linked video. Compare the requested band/channel changes with the observed resets to channel 1 or 7, and document a reproducible cause and verified fix.
Written by the indexing model from the issue text.
Description
Connected as below (pins go from left to right -> from top to bottom -> CLK(Reset), DATA(RX pin) NSS(TX pin):
The firmware in the happymodel EP2 is "Skyzone Steadyview/ELRS Receiver (DIY)"
But it's weird - on changing band/channel from VTX Admin lua it opens menu, resets the channel to 1 or to 7, does not change the band.
