Peripheral Examples

LoRa (SX1262)

#include <RadioLib.h>

// SX1262: CS=8, IRQ=14, RST=5, BUSY=13 (T-LoRa C6)
SX1262 radio = new Module(8, 14, 5, 13);

void setup() {
  Serial.begin(115200);
  int state = radio.begin(915.0);
  if (state != RADIOLIB_ERR_NONE) {
    Serial.print("Radio init failed: "); Serial.println(state);
    while (true);
  }
  radio.setOutputPower(22);
  Serial.println("SX1262 ready");
}

void loop() {
  String msg = "Hello from T-LoRa C6";
  int state = radio.transmit(msg);
  if (state == RADIOLIB_ERR_NONE) Serial.println("Sent OK");
  delay(2000);
}
