3.1.5.1 Execution

main.c - Initialize the ATWINC15x0/ATWINC3400 and act as an AP.

  1. Code summary:
    • Configure the network parameters in main.h.

// #define USE_WEP			2 /* WEP Security Mode*/
// #define USE_OPEN		3 /* No Security or OPEN Authentication Mode*/

    • In the main() function, initializes the AP mode configuration structure (strM2MAPConfig) , see the following example. User can enable the AP mode via m2m_wifi_enable_ap() function. Users may choose any of the available security methods according to the requirements.
      /* 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] = 192;
    strM2MAPConfig.au8DHCPServerIP[1] = 168;
    strM2MAPConfig.au8DHCPServerIP[2] = 1;
    strM2MAPConfig.au8DHCPServerIP[3] = 1;
#if USE_WEP
    strcpy((char *)&strM2MAPConfig.au8WepKey, MAIN_WLAN_WEP_KEY);

#endif

    strM2MAPConfig.u8KeySz = strlen(MAIN_WLAN_WPA_PSK);
#endif
    /* Bring up AP mode with parameters structure. */
    ret = m2m_wifi_enable_ap(&strM2MAPConfig);
    printf("AP mode started. You can connect to %s.\r\n", (char *)MAIN_WLAN_SSID);
  2. Build the program and download it into the board.
  3. Start the application.
