/** 
 * This example uses Remote AT to turn on/off I/O pins.  
 * This example is more interesting if you connect a LED to pin 20 on your end device.  
 * Remember to use a resistor to limit the current flow.  I used a 215 Ohm resistor.
 * 
 * Note: if your coordinator is powered on and receiving I/O samples, make sure you power off/on to drain 
 * the traffic before running this example.
