He probado varios módulos lora con el ESP32, que tengo por aquí y antes o después, aparecerán en forma de tutos en estas humildes páginas, pero de momento me ha parecido mas educativo usar los módulos LORA / LORAWAN con el M5Stack porque al final son bastante estándar con el ESP32 y sobre todo porque no hay que preocuparse de pines raros y la sesión queda muy limpia

The IoT industries introduced lots of technologies, but none of them was ideal for IoT devices, as they needed to transmit information to a long distance without using much power until the LoRa technology was introduced. LoRa Technology can perform very-long range transmission with low power consumption. According to Industry analyst IHS Market by 2023, 43% of all LPWAN connections will be based on LoRa. LoRa Technology is flexible for smart cities, smart homes, smart agriculture, smart metering, and smart supply chain & logistics applications. Previously we learned about LoRa technology and interfaced SX1278 Lora Module with Arduino. Now we will replace the Arduino, and use ESP32 with the SX1278 LoRa module. Here two LoRa modules will be interfaced with two ESP32 Boards to send and receive data packets from one board to another. ESP32 is a very popular Wi-Fi transceiver and microcontroller, learn more about ESP32 and its working by going through various IoT applications built on it.
