NMI_API sint8 m2m_wifi_wps	(	uint8	u8TriggerType,
		const char *	pcPinNumber
	)

Asynchronous API to engage the WINC IC's Wi-Fi Protected Setup (enrollee) function.

This function is called for the WINC to enter the WPS (Wi-Fi Protected Setup) mode. The result 
is passed to the Wi-Fi notification callback with the event @ref M2M_WIFI_REQ_WPS.

Parameters

[in]	u8TriggerType	WPS Trigger method. This may be: WPS_PIN_TRIGGER Push button method WPS_PBC_TRIGGER Pin method
[in]	pcPinNumber	PIN number for WPS PIN method. It is not used if the trigger type is WPS_PBC_TRIGGER. It must follow the rules stated by the WPS standard.

Precondition

A Wi-Fi notification callback of type (tpfAppWifiCb MUST be implemented and registered at startup. Registering the callback is done through passing it to m2m_wifi_init.
The event M2M_WIFI_REQ_WPS must be handled in the callback to receive the WPS status.
The WINC device MUST be in IDLE or STA mode. If AP mode is active, the WPS will not be performed.
The m2m_wifi_handle_events MUST be called periodically to receive the responses in the callback.

Warning: This function is not allowed in AP mode.

Returns: The function returns M2M_SUCCESS if the command has been successfully queued to the WINC and a negative value otherwise.
