Dependencies:   NNN50_WIFI_API

This is a must try example for basic WIFI functions using DELTA DFCM-NNN50 platform. In order to test with this example, user first need to open UDP Server port (use 1030 in this example) on a PC or mobile with Socket test tool (download UDP Test Tool' for PC, and Socket X for iOS or anymore socket test tool program available) When this example is running, the module will connect to a pre-defined AP router and run as UDP Client. For more information on the usage of regular TCP and UDP Sockets, the mbed handbook can be found here
