I's not transparent. Unfortunately.
It expects a frame format like the one from the FrSky Telemetry hub.
FrSky was nice enough to publicly document that data format.
But it's rather useless for us as telemetry link. And there is no word
on througput and latency.
But you could, and that would actually be a brilliant idea, encode some
status information from the autopilot and send it down the FrSky
telemetry link.
It supports things like Altitude, GPS NEMA stream, airspeed, current,
voltages, accelerations. And there are two analog ports for practically
free use.
All that is publicly documented and could easily be implemented.
