Telemetry , lora sx1278

I want help for make radio telemetry for my pixhawk plane , i have two sx1278 , 433mhz modules whitch have 1000mw output power , and ttl to serial usb
But i dont know how i should connect them to pixhawk and pc to make wireless connection between them for my arduplane

Tnk U

I have a pair of these but i havent gotten around to testing them, i belive it needs to be set to a bidirectional transparent serial mode to work with mavlink.

How i can set them to this mode, can you explain more plz
