Fail to connect pixhawk 6x to QGC through telemetry radio

I have a Pixhawk 6x and “RFD900X” telemetry radio. I connected one telemetry to the pixhawk in port “TELEM 1” and connected another telemetry to my laptop. They were matched but there was no response in the QgroundControl.

Qground Control is working when I connect the pixhawk to my laptop through type C usb cable.

I was used to using “RFD900X” telemetry radio with Holybro pixhawk 4 and it is able to connect to QgroundControl through telemetry radio. However, Holybro pixhawk 4 is no longer in production. That’s why it is neccessary for me to use Holybro pixhawk 6x.

Here is the information of my device:

  • Firmware: px4_fmu-v6x_default
  • Product: Holybro Pixhawk 6x
  • Telemetry Radio: RFD900X

Did someone connect holybro pixhawk 6x to QgroundControl through telemetry Radio successfully?

Thanks for your time.
