I have some working code, but I’m not sure why this works but the other didn’t

replaced :

for(int i=0; i<5; i++)
//remember, you could use an if() here to check for new data, this time it’s not needed.
//set our LED on or off based on what we received from the other Arduino
digitalWrite(13, rxdata.buttonstate);

//set our servo position based on what we received from the other Arduino
//we will also map the ADC value to a servo value
myservo.write(map(rxdata.servoval, 0, 1023, 0, 179));



while(   ! ET_RECV.receiveData()  )
//                Serial.println(“waiting for data”);
//                delay(1);
}  //end of while not received

the print and delay was just to see what was happening. Code works without them …sent address value = received. Now need to add timeout code if node doesn’t respond within a certain time.

Is there a method available for that already?
