Herelink and iPad

Just a quick question: Is there a possibility to use/abuse the herelink air unit on the ground for integration with an iPad app? In the documentation it was listed the herelink air unit only has video in. Guess there is no version with video out? What about the UART can this be used in combination with MAVLINK on the ground? Is the UART two way? So can I use two Herelink air units for communication?

Or is another possibility to use the WiFi connection between the Herelink Ground unit and the iPad? Would we have a video stream? Can we communicate with the autopilot? Again using mavlink?

It should be possible, as long as you know the ip and port
