I found documentation about fport, if it helps you. I do not understand how to make it. https://github.com/betaflight/betaflight/files/1491056/F.Port.protocol.betaFlight.V2.1.2017.11.21.pdf

try to downgrade opentx version... it looks like opentx development is near to end. Or try to use EdgeTx.

There is some documentation for access #239
