Spektrum receiver not connecting



  • After setting up a flight core as recommended and upgrading firmware to modalai_fc-v1_default.px4 we connected a Spektrum SPM9745 to port 12 using the supplied MCBL-00005 cable. Using QGround Control we then opened the radio tab, clicked on Spektrum Bind, and selected DSMX-8. We then powered on our DX8e with the bind button pressed. The blinking orange LED changed to constant and the DX8e showed DSMX bound. All this looks OK, but when we press the calibrate button and OK we receive the message "Detected 0 radio channels. To operate PX4, yu need at least 5 channels." We've repeated this process many times with similar results. Can you suggest what is not correct?



  • @Jimk_Aero Please ignore the previous question. I just needed to reboot the Flight Core and all is OK.
