/*
 * Application Name     -   Getting started with Wi-Fi Access-Point mode
 * Application Overview -   This sample application demonstrates how
 *                          to configure CC3100 in Access-Point mode. Any
 *                          WLAN station in its range can connect/communicate
 *                          to/with it as per the standard networking protocols.
 *                          On a successful connection, the device ping's the
 *                          connected station.
