Hey PaulS
Yeah sorry I completely overlooked that part, there is a loop within the code where it checks if a packet has been received. Within this loop I added a few lines to make an led blink.
if (Serial.available() > 0) {
incomingByte = Serial.read();
digitalWrite(led, HIGH);
delay(1000);
digitalWrite(led, LOW);
delay(1000);
plm1_send_data(&incomingByte, 1);
}
Also added in the setup:
pinMode(led, OUTPUT);
There is a Status Led on the Shield that is green while idling, prior to the alteration the led is lit. After the Code is uploaded the LED doesn't light up.
Cheers for bringing that to my attention.
