static void wifi_cb ( uint8_t  u8MsgType, void *  pvMsg  )

static

Callback to get the Wi-Fi status update.

Parameters

[in]	u8MsgType	type of Wi-Fi notification. Possible types are: M2M_WIFI_RESP_CURRENT_RSSI M2M_WIFI_RESP_CON_STATE_CHANGED M2M_WIFI_RESP_CONNTION_STATE M2M_WIFI_RESP_SCAN_DONE M2M_WIFI_RESP_SCAN_RESULT M2M_WIFI_REQ_WPS M2M_WIFI_RESP_IP_CONFIGURED M2M_WIFI_RESP_IP_CONFLICT M2M_WIFI_RESP_P2P M2M_WIFI_RESP_AP M2M_WIFI_RESP_CLIENT_INFO
[in]	pvMsg	A pointer to a buffer containing the notification parameters (if any). It should be casted to the correct data type corresponding to the notification type. Existing types are: tstrM2mWifiStateChanged tstrM2MWPSInfo tstrM2MP2pResp tstrM2MAPResp tstrM2mScanDone tstrM2mWifiscanResult
