//!   \brief Connecting to a WLAN Accesspoint using SmartConfig provisioning

//!    This function enables SmartConfig provisioning for adding a new 
//!    connection profile to CC3200. Since we have set the connection policy

//!    automatically to the new connection profile added by smartConfig.

//!                         IP address,We will be stuck in this function forever.
