Off-Grid Live Chat Without Internet 📡 | ESP32 + LoRa SX1278 (RA-02) Web & Mobile DIY

In this project, I built an off-grid live chat system using 2 ESP32 boards and LoRa SX1278 (Ra-02) modules. This system allows real-time messaging without any internet connection. I connected both mobile devices and a web interface to create a complete communication system that works over long distances using LoRa technology. 🔧 What I used: 2x ESP32 2x LoRa SX1278 (Ra-02) modules Mobile + Web interface 🚀 Features: Off-grid communication (no WiFi / no internet) Live chat between devices Long-range wireless messaging Works with both mobile and web This project is perfect for remote areas, emergency communication, and DIY wireless systems.
