Jan Jongboom 1:b604a2d6c54d 5 1. Triggers transmission when D6 goes high - this is the special wake-up pin on the mDot. Short D6 to test quickly.
Jan Jongboom 1:b604a2d6c54d 6 2. The RX window is used to toggle D2. If 0x00 is received the pin goes high, if 0x01 is received the pin goes low (as the LEDs are inverted on the break-out board).
