Air unit as ground module - OEM documentation request

I am sure I have seen somewhere a discussion about the use of a second air unit switched over to be used as a ground station instead of using the herelink controller.

Is there any documentation or info about how to do this, configure it etc? We are finding the hand held unit unsuitable for long range applications and a simple ground module would be far more useful.

We are working on this but it is not ready to be released yet.
