Building a Pocket-Sized LoRa Messenger for Hiking & Emergencies RJT642

Описание: Discover how to build the ultimate off-grid communication device! In this step-by-step tutorial, we create a secure, private LoRa messenger using the powerful Heltec WiFi LoRa 32 (ESP32) module. Learn how to use a rotary encoder as a unique and practical keyboard to type and send encrypted messages without needing Wi-Fi or a SIM card. This project is perfect for emergency situations, hiking, or any scenario where you need reliable, long-range communication. We'll cover the complete build process, including wiring, library installation in the Arduino IDE, and a real-world demonstration where we test the device over an incredible 13-mile (21km) range! All code and resources are linked below.
