Hello everyone,
I have 3 RFD900x devices. I connect the master rfd900x via FTDI cable to the PC. I am using multi point firmware on RFD900x devices. When I try to load settings on SİK radio, ı receive error that ‘Invalid ComPort or in use’. Because of that I can not connect to mission planner or QGroundControl. Also when ı try to connect to QGroundControl, I receive this massage.
Thank you for your answer but I checked and there is nothing to allocate my com port. I think there is a problem about firmwares. Because when I upload to SİK firmware to my rfd900x device, ı can connect easly to qgroundcontrol or mission planner. But when I upload multi point firmware to rfd900x, i cannot connect any of them.
It is not about com port, i checked that several times. I can connect with RFD Tools and i can change the settings in this tool. But I have to open this RFD on QgroundControl.
As you can see I can connect RFD devices via mission planner. But I can not access SIK Radio tool on mission planner. When I try it, it gives me this error,
