00038  * Application Name     -   Getting started with Wi-Fi Access-Point mode
00039  * Application Overview -   This sample application demonstrates how
00040  *                          to configure CC3100 in Access-Point mode. Any
00041  *                          WLAN station in its range can connect/communicate
00042  *                          to/with it as per the standard networking protocols.
00043  *                          On a successful connection, the device ping's the
00044  *                          connected station.
