3.1.12.1 Execution

Code summary:

Case 1: WEP Security Method

To test WEP security, modify MAIN_WLAN_DEVICE_NAME, MAIN_WLAN_WEP_KEY_INDEX and MAIN_WLAN_WEP_KEY_40 or MAIN_WLAN_WEP_KEY_104 in main.h.

/** security information for Wi-Fi connection */
#define MAIN_WLAN_DEVICE_NAME           "DEMO_AP" /**< Destination SSID */
#define MAIN_WLAN_WEP_KEY_INDEX         1 /**< WEP key index */
/**< 64 bit WEP key. In case of WEP64, 10 hexadecimal (base 16) characters (0-9 and A-F) ) */
#define MAIN_WLAN_WEP_KEY_40            "1234567890" 
/**< 128 bit WEP key. In case of WEP128, 26 hexadecimal (base 16) characters (0-9 and A-F) ) */
#define MAIN_WLAN_WEP_KEY_104           "1234567890abcdef1234567890"

When pressing the SW0 button on the SAM D21, it will trigger WPS in the btn_press() function.

/** Security parameters for 64 bit WEP Encryption @ref m2m_wifi_connect */
tstrM2mWifiWepParams wep64_parameters = { MAIN_WLAN_WEP_KEY_INDEX, 
                                        sizeof(MAIN_WLAN_WEP_KEY_40),
                                        MAIN_WLAN_WEP_KEY_40};
/** Security parameters for 128 bit WEP Encryption @ref m2m_wifi_connect */
tstrM2mWifiWepParams wep128_parameters = { MAIN_WLAN_WEP_KEY_INDEX,
                                          sizeof(MAIN_WLAN_WEP_KEY_104),
                                          MAIN_WLAN_WEP_KEY_104};

/* Case 1. Connect to AP with security type WEP. */
m2m_wifi_connect((char *)MAIN_WLAN_DEVICE_NAME, strlen((char *)MAIN_WLAN_DEVICE_NAME),
     M2M_WIFI_SEC_WEP, &wep64_parameters, M2M_WIFI_CH_ALL);

Case 2: WPA-PSK Security Method

To test WPA security, use case 2 in the main() function and modify MAIN_WLAN_PSK in main.h.
```
#define MAIN_WLAN_PSK     "12345678" /**< Password for Destination SSID */
```

Connect to the AP with the given information.

/* Case 2. Connect to AP with security type WPA. */
m2m_wifi_connect((char *)MAIN_WLAN_DEVICE_NAME, strlen((char *)MAIN_WLAN_DEVICE_NAME),
     M2M_WIFI_SEC_WPA_PSK, (char *)MAIN_WLAN_PSK, M2M_WIFI_CH_ALL);

Prepare an AP that supports WEP and WPA/WPA2 Security and configure its Wi-Fi Security. For more information, refer to the AP manufacturer's manual.

Run the application. If the device connected successfully, the IP address assigned by DHCP will be displayed on the terminal program.
