Avnet / Mbed 2 deprecated WNCInterface_M2Xdemo

This example program uses the ARM mbed HTTP client library to send/receive data to/from AT&T's M2X service (https://m2x.att.com/) using the AT&T Cellular IoT Starter Kit from Avnet (http://cloudconnectkits.org/product/att-cellular-iot-starter-kit). This kit contains a FRDM-K64F from NXP (https://developer.mbed.org/platforms/FRDM-K64F/).

Dependencies:   M2XStreamClient-JMF WNCInterface jsonlite 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.
