RF24 radio(9, 10); // CE, CSN
const byte address[6] = "mkinventions100";
void setup() {
radio.begin();
radio.openWritingPipe(address);
radio.setPALevel(RF24_PA_MIN);
radio.stopListening();
}
void loop() {
const char text[] = "Hello World! This is Madhan";//print only 32 characters
radio.write(&text, sizeof(text));
delay(1000);
}
