Pair lora 32u4 with dorji drf 1276 module

Goal use lora 32u4 as a node for gps tracking. Send coordinates to a dorji drf 1276 module with a serial connection to a mac laptop.

I am able to do this operation with a pair of 1276 modules and an esp32 dev kit c.

I would like to replace the esp32 and drf 1276 module with lora 32u4 board.

How would I configure the dorji 1276 module to communicate with a lora 32u4 board?

Thanks for your help

Sorry, this forum is about LoRaWAN, not Lora point to point connections.
