Mission planner protocols

hello everyone, I would like to know if mission planner supports any other protocols except Mavlink protocol (multi-wii serial protocol, cellular telemetry protocol ) or not .
thanks,

It supports NTRIP, MAVlink and other protocols, but not milti-wii

What is celular telemetry protocol? Is that even a thing?

thanks sir, inav supports Mavlink in transmission only so if I connect it with the mission planner I can monitor my drone without sending any commands to it, inav supports Cellular telemetry via text messages so you can connect SIM800 series cellular module to provide telemetry via text messages.
