ibrahim momoh / Mbed 2 deprecated ESP8266-configuration-mbed-K64F

IUPUI ESP8266 config code for IU Device net, make sure you first run this , get the MAC address of you module, register the device with IU Device net. after that there is no need for a password, just run this program once on your module, it will save password

Dependencies:   mbed
