Fpv drone bound to radio but doesn’t fly or show up in betaflight

[Satpreet.d]

I’m new into fpv and I bought the mobula7 with elrs version but since I have a radiomaster boxer 4in1 protocol so I bought a RadioMaster - R81 2.4GHz 8ch Frsky D8 Nano RX and bound it to to radio it says telemetry recovered but it doesn’t fly or show up in betaflight. It was a sbus so I soldered the gnd to the vtx gnd, the positive to 5v, and the sbus to rx2. I have the uart 2 serial Rx switch on and i changed to configuration to serial rx and sbus as well but I don’t know what I’m doing wrong.

The Mobula7 has an SPX receiver built into the flight control board and it cannot recognize both RXs. You will need to get an ELRS module for the radio in order to bind to it.
