Code

Arduino Sketch to send and receive messages over LoRa (433 MHz)

Arduino
#include <SPI.h>
#include <LoRa.h>

void setup() {
  Serial.begin(115200);
  while (!Serial);

  Serial.println("LoRa Sender / Receiver (434 MHz)");

  if (!LoRa.begin(434E6)) {
    Serial.println("Starting LoRa failed!");
    while (1);
  }
}

void loop() {
  // try to parse packet
  int packetSize = LoRa.parsePacket();
  if (packetSize) {
    // received a packet
    Serial.print("Received: ");

    // read packet
    while (LoRa.available()) {
      Serial.print((char)LoRa.read());
    }
  }

  // Send
  if (Serial.available() > 0) {
    Serial.print("Sending: ");
    LoRa.beginPacket();
    while (Serial.available() > 0) {
      char c = Serial.read();
      Serial.print(c);
      LoRa.write(c);
    }
    Serial.println();
    LoRa.endPacket();
  }
}
