main.c - Initialize the ATWINC15x0 and start Provision mode until one of various APs is selected.

Code summary:

Initialize the socket module and create the TCP server socket.

/* Initialize socket address structure. */
addr.sin_family = AF_INET;
addr.sin_port = _htons((MAIN_WIFI_M2M_SERVER_PORT));
addr.sin_addr.s_addr = 0;
/* Initialize Socket module */
socketInit();
registerSocketCallback(socket_cb, NULL);
while (1) {
    m2m_wifi_handle_events(NULL);
    if (tcp_server_socket < 0) {
    /* Open TCP server socket */
    if ((tcp_server_socket = socket(AF_INET, SOCK_STREAM, 0)) < 0) 
    /* Bind service*/
    bind(tcp_server_socket, (struct sockaddr *)&addr, sizeof(struct sockaddr_in));

Enable AP mode before the main loop. (Refer to the “How to Run AP Mode” example.)

/* Initialize AP mode parameters structure with SSID, channel and OPEN security type. */
	memset(&strM2MAPConfig, 0x00, sizeof(tstrM2MAPConfig));
	strcpy((char *)&strM2MAPConfig.au8SSID, MAIN_WLAN_SSID);
	strM2MAPConfig.u8ListenChannel = MAIN_WLAN_CHANNEL;
	strM2MAPConfig.u8SecType = MAIN_WLAN_AUTH;
	strM2MAPConfig.au8DHCPServerIP[0] = 0xC0; /* 192 */
	strM2MAPConfig.au8DHCPServerIP[1] = 0xA8; /* 168 */
	strM2MAPConfig.au8DHCPServerIP[2] = 0x01; /* 1 */
	strM2MAPConfig.au8DHCPServerIP[3] = 0x01; /* 1 */

	/* Bring up AP mode with parameters structure. */
	ret = m2m_wifi_enable_ap(&strM2MAPConfig);

After your Android device is connected to the ATWINC15x0 and sends the AP configuration, disable AP mode and connect to the AP with the given information.

static void socket_cb(SOCKET sock, uint8_t u8Msg, void *pvMsg)
{
    case SOCKET_MSG_RECV:
    {
        printf("Disable to AP.\r\n");
	 m2m_wifi_disable_ap();
	 nm_bsp_sleep(500);
	 printf("Connecting to %s.\r\n", (char *)str_ssid);
	 m2m_wifi_connect((char *)str_ssid, strlen((char *)str_ssid), sec_type, str_pw, M2M_WIFI_CH_ALL);

The wifi_cb() function is called with the M2M_WIFI_REQ_DHCP_CONF message and then receives an IP address.

static void wifi_cb(uint8_t u8MsgType, void *pvMsg)
{
    case M2M_WIFI_REQ_DHCP_CONF:
    {
	uint8_t *pu8IPAddress = (uint8_t *)pvMsg;
	printf("Wi-Fi connected\r\n");
	printf("Wi-Fi IP is %u.%u.%u.%u\r\n",
			pu8IPAddress[0], pu8IPAddress[1], pu8IPAddress[2], pu8IPAddress[3]);
