I'm currently stuck with my build and by now I've almost given up, maybe some of you can give me a new idea.
I have the Betaflight F3 flight controller and the X4R-SB receiver. The problem I'm having is that in the betaflight configurator program, when I go to the receiver tab I can move my sticks around but nothing will happen. I'm using the Taranis Q X7 transmitter. Here is what I did:
- Flashed my internal transmitter module and receiver to the latest EU version.
- I soldered the white signal wire from the X4R-SB to the sbus port.
- Soldered the red and black wire to the grnd and 5v/3v ports next to it.
- Made sure sure the rx gets 5v supplied.
- Soldered the yellow smartport wire to the tx port on UART 1.
- Supplied power and paired the transmitter/receiver (no problem)
- Connected to Betaflight configurator, made sure of the following settings:
- Under ports tab: UART2 set to Serial RX, UART1 set to smartport.
- Under configuration tab: Set Receiver to Serial-based receiver and provider to SBUS. Also made sure the Telemetry option is checked.
- Under receover tab: Made sure the channel map is set to TAER1234
- With everything powered on: Try to move sticks on the transmitter, see that nothing happens in the configurator.
