Is your feature request related to a problem?

I would like to interact with the TX module, receiver, flight controller, etc from external devices connected via Mirror Telemetry.
This will allow you to load waypoints and set safe landing points directly during the flight.
It will also be possible to manage settings from a phone or tablet (when using the CRSF protocol).

Describe the solution you'd like

Now in the Mirror Telemetry mode I receive bare protocol data. In the case of CRSF, these are not only telemetry packets, but also synchronization packets, and when calling the ELRS/TBS lua script - also responses to Ping, Entry, Read, etc. requests. But I can't send these requests (Ping, Write).

It would be great if external devices could form their own packets and send them to the transmission module.

Describe alternatives you've considered
