P2P LoRa communication (Non Arduino IDE)

Hello Folks,

I am planning to build an actual product having two LoRa Modules in a P2P setup. I have two SeeedStudio LoRa-E5 mini dev. kits to test a P2P configuration. I see your Wiki page shows how to setup one of this kits to send data to the TTH.

Do you have a step by step tutorial and library to send/receive P2P data between two LoRa-E5 mini dev. kits without using Arduino Libraries?
