Ok, so I'm having a nightmare with the frsky rsxr-fc flight controller. It is the omnibus f4 v6 with a pre-installed rsxr on board with a protective cover. As per the instructions I've flashed the fireworks v2 firmware, went ahead and calibrated the gyro, set up the motors, and I can power the motors up inside inav. But I get no response in the receiver tab. I have already tried betaflight, where you have to change to the 2nd gyro and set the roll to 180 degrees, then set up smartphone on soft serial, using the cli, and couldn't get a response inside betaflight. I bound the receiver and have a good steady green light..... can anyone help me? Give me an idea of what to look for that might be wrong in a cli dump all? I thought it might have been that the flight controller thought it was upside down, but all responses are correct on the first tab, so I don't think that's it......any help would be awesome.

It’s probably the RSXR rx firmware not matching your radio firmware which is why you get no response in the receiver tab. What radio are you using?

We had a thread on this recently on the forum. See if any of the suggestions help: https://intofpv.com/t-firmware-problem-w...omnibus-fc
