cc3200 网页控制

CC3200在连接到AP后保存Profile，在CC3200再次启动后，注意不要将所有的Profile删除，否则就无法连接到你之前记录的路由器AP上了，在程序中查找

//*****************************************************************************
//! \brief This function puts the device in its default state. It:
//! - Set the mode to STATION
//! - Configures connection policy to Auto and AutoSmartConfig
//! - Deletes all the stored profiles  -----------------------------------------------------------这个地方不要打开，否则会删除所有的Profile
//! - Enables DHCP
//! - Disables Scan policy
//! - Sets Tx power to maximum
//! - Sets power policy to normal
//! - Unregister mDNS services
//! - Remove all filters
//!
//! \param none
//! \return On success, zero is returned. On error, negative is returned
