La primera duda es que módulo de radio o transceiver usar el RFM69 o RFM95: RFM69 no es LoRa usa modulación FSK en lugar de la modulación LoRa; RFM95 es LoRa estándar. RFM69 y RFM95 son módulos de radio para comunicación a larga distancia, donde la velocidad de transmisión no es crítica (no se hace streaming de vídeo). So, in this tutorial we will learn how to use a LoRa module SX1278 with Raspberry pi to communicate with another SX1278 connected to a microcontroller like Arduino. This method can come in handy at many places since the Arduino could act as a Server to fetch data from sensors and send it to Pi over a long distance through LoRa and then the Pi acting as a Client can receive these information ...
