When I have it set to the 64 version of 9XR, I cant even read the firmware from the radio in the Companion. With the m128 selected, its able to read the firmware that is currently on it and save it to my computer in a file. Going to try and force OpenTX on it now. To get FrSky telemetry working on it, I believe you have to do some modding to the board first, and then use a specific FrSky capable firmware.
