Integrate mission planner with a wireless microcontroller

i have to integrate the software with a microcontroller that has its software in C language and only uart communication is possible that doesn’t have MAV link protocol. how can i do this ?

You can use an ESP32 and connect it via UART with ArduPilot. It is possible and works great. ESP32 board prices start at 4 Euros.

Can get some references and I need to establish the connectivity with texas wireless microcontroller
