This Project demonstrates AES encryption/decryption in a Duplex and P2P configuration using the LoRa protocol.
Dependency: https://github.com/josephpal/esp32-Encrypt we will need this repository added as a library to the Arduino IDE.
Prerequisite: 2 LoRa32 boards (2 ESP32 boards with an attached antenna, LoRa module and oled display each).
There are 2 ways to see the i/o:
Serial i/o (using Bluetooth or Arduino console)
Oled display
