NMI_API sint8 m2m_wifi_disable_ap

(

void

)

Synchronous API to disable access point mode on the WINC.

Synchronous API to disable access point mode on the WINC IC.

Must be called only when the AP is enabled through the @ref m2m_wifi_enable_ap
function. Otherwise the call to this function will not be useful.

Returns

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

NMI_API sint8 m2m_wifi_enable_ap

(

CONST tstrM2MAPConfig *

pstrM2MAPConfig

)

Asynchronous API to enable access point (AKA "hot-spot") mode on the WINC.

Asynchronous API to enable access point (AKA "hot-spot") mode on the WINC IC.

The WINC supports the ability to operate as an access point with the following limitations:
- Only 1 station may be associated at any given time.
- Open system and WEP are the only security suites supported.

Parameters

[in]

pstrM2MAPConfig

A structure holding the AP configurations.

Returns

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

Warning

This function is not allowed in P2P or STA modes.

Precondition

• A Wi-Fi notification callback of type tpfAppWifiCb MUST be implemented and registered at initialization. Registering the callback is done through passing it to the m2m_wifi_init.
• The event M2M_WIFI_REQ_DHCP_CONF must be handled in the callback.
• The m2m_wifi_handle_events MUST be called to receive the responses in the callback.

Example

The code snippet demonstrates how the AP mode is enabled after the driver is initialized in the application's main function and the handling of the event M2M_WIFI_REQ_DHCP_CONF, to indicate successful connection.

#include "m2m_wifi.h"

        }
        break;

    default:
        break;
    }
}

int main()
{
    tstrWifiInitParam param;
    param.pfAppWifiCb = wifi_event_cb;
    if(!m2m_wifi_init(&param))
    {

        strcpy(apConfig.au8SSID, "WINC_SSID");
        apConfig.u8ListenChannel = 1;
        apConfig.u8SecType       = M2M_WIFI_SEC_OPEN;
        apConfig.u8SsidHide      = 0;

        // IP Address
        apConfig.au8DHCPServerIP[0] = 192;
        apConfig.au8DHCPServerIP[1] = 168;
        apConfig.au8DHCPServerIP[2] = 1;
        apConfig.au8DHCPServerIP[3] = 1;

        // Trigger AP
        m2m_wifi_enable_ap(&apConfig);

        while(1)
        {
            m2m_wifi_handle_events(NULL);
        }
    }
}
