ExpressLRS - MAVLink -RC Telemetry Setup

Step 1:- Update your ELRS Module framewear 3.5.0 And Up Framewear ( Receiver And Module) (The minimum versions to use this feature are: - Transmitter / receiver firmware: 3.5.0 - TX)

Step 2:- You first need to go to your radio setup and configure the Express LRS module and then go to the Link Mode option. Change it from Normal to MAVLink.
