Hi Eoreh

Maybe problem is in this line:
digitalWrite(D3, HIGHT); delay(2);

Did you defined HIGHT symbol?

Actually I did it this way:

void WakeUp()
{
  pinMode(DEVICE_DETECT_PIN, OUTPUT);
  digitalWrite(DEVICE_DETECT_PIN, HIGH);
  delay(1000);
  digitalWrite(DEVICE_DETECT_PIN, LOW);
  delay(1000);
  digitalWrite(DEVICE_DETECT_PIN, HIGH);
}

and it works flawlessly (Ihave other problem with hanging NRF24, but it is another case)
