void wifi_ap_connect ( wifiProvisionParams provParams)

Wi-Fi Provisioning ap connect function.

This will connect to the AP with the credentials received in wifiProvisionParams The user is expected to perform m2m_wifi_init() before calling this api.

Referenced by main().

void wifi_ap_provision ( wifiProvisionParams provParams)

Wi-Fi Provisioning main application function.

This is a blocking function that wait for the user to connect to the PROV_WLAN_SOFTAP_SSID and provide the credentials in web page http://192.168.1.1/provisioning.html. The user is expected to close all the open socket and perform socketDeinit() and m2m_wifi_deinit before this function is called
