Avnet / Mbed 2 deprecated WNCInterface_HTTP_example

This Socket Example Program Implements a TCP Socket, UDP Socket, and HTTPClient socket then uses each of these to perform basic I/O.

Dependencies:   JSON M2XStreamClient-JMF WNCInterface mbed-rtos mbed

See the README for details on this example program. NOTE: When started, the program can take up to 40 seconds before it will respond. This delay is the time required for the WNC Data Module to connect with the network.
