Mocktastic: A Meshtastic Node on Arduino

Mocktastic is an educational Meshtastic-compatible LoRa client for ESP32 boards built with Arduino IDE that demonstrates how to construct and decode Meshtastic packets in C++. The project offers two compile-time modes: a DECODER mode for receiving and sending messages on Meshtastic channels, and a SENSOR mode that turns the board into a temperature and humidity sensor. It uses libraries like mbedTLS for cryptography and Nano-Protobuf for encoding, with the implementation targeting the LilyGO T3 LoRa32 board but designed to be adapted to other compatible hardware.
