This also demonstrates how multiple commands could be sent at once. The sensor 
always sends its packets back to the source port specified in the original packet.  
Note 
If a response is not received, try sending either the 'A1' or 'A0' 
command to turn on and off the LED. If the LED responds, the node is 
receiving the message, but the response is not being passed back. 
Running Wireshark on the interface may provide some useful 
information, such as if the UDP response packet has an incorrect 
checksum.

The commands which can be sent are shown in the following table, and must also 
end with either a <LF> or <CR><LF> combination.
