SPM4650 connecting to Matek H743-wlite - no radio signal

Receiver is connected to TX6 per Matek’s site. Serial 6 is set up protocol - 23, Options - 4, RSSI is set to 3. But there is no response in radio calibration. receiver is bound to transmitter. What am I missing?

  • Make sure your transmitter is powered on before powering the flight controller
  • If that doesn’t help try options 12

Still no luck. I have baud set to 115. Don’t know if that is what it should be set to.

Doesn’t matter, it will be set by the protocol handler.

TX6 is SERIAL7 - that will be the problem!

Ha. I had a stupid moment(a few of them). I knew that. thanks.
