AT&T Developer Summit Hackathon 2016 / Mbed 2 deprecated M2X_Nucleo411_ESP8266-wifi Featured

Example of using the ATT M2X back end. Connect over Wifi with the ESP8266 chip. This code sends random data to M2X. This code can be used for Any board, just change the RX/TX pins the wifi adapter is connected to.

Dependencies:   ESP8266Interface M2XStreamClient jsonlite mbed
