Connecting two ESP32 cards

I got two lilygo T3 v1.6.1, i nee to connect the two of them via LoRa but i can't find help on the internet. (sorry for the orthograph, i'm french)

The LilyGo boards I purchased came with instruction links in the package. I have used that to have the two boards communicating over a distance of several hundred yards through 4 apartment building walls.

Per LilyGo "We provide entry-level sample code for most of our products to help learners get up and running with these boards faster." Have you tried there website?

the SX12XX LoRa Library supports a range of LoRa modules including the SX1262 and SX1276
It also comes with a number of example programs for LoRa P2P communication, e.g. post heltec-wireless-tracker-to-esp32c3-mini-via-lora

yeah and i can't find the said code

it's for a school project so it was purchase from a seconde hand website so no notice or anything like that

do you know which specific LoRa module your lilygo T3 v1.6.1 has?
what do you select under Tools>Board?
can you load simple programs such as Blink?

Search github for lilygo. You will find hundreds of repositories. Refine the search with the exact writing on your board.
