Arduino​ Reyax RYLR896 LoRa Transceiver Module Project Code (Transmitter)

C/C++
#define ledPin 2
unsigned long lastTransmission;
const int interval = 1000;

void setup(){
    Serial.begin(115200);
    pinMode(ledPin,OUTPUT);
}

void loop(){
    if (millis() > lastTransmission + interval){
        Serial.println("AT+SEND=0,8,Testing!");
        digitalWrite(ledPin,HIGH);
        delay(100);
        digitalWrite(ledPin, LOW);
        lastTransmission = millis();
    }
