Transmit Operation

Transmit operation begin with calling beginPacket() method following by write() method to write package to be tansmitted and ended with calling endPacket() method. For example, to transmit "HeLoRa World!" message and an increment counter you can use following code.

// message and counter to transmit
char message[] = "HeLoRa World!";
uint8_t counter = 0;

LoRa.beginPacket();
LoRa.write(message, sizeof(message)); // write multiple bytes
LoRa.write(counter++);                // write single byte
LoRa.endPacket();
LoRa.wait();
