UDP Echo Sketch for Spark Core
A simple UDP echo program for the Spark Core Arduino based device. You can send a single byte (ie. 'a') of data and have it sent back. This program serves no real practical application, but can be used to learn and tinker with UDP and inter-device communication.
You can test sending and receiving UDP packets using the Packet Sender application, available for Windows, Mac, Ubuntu and Andriod.
