3.1.3.1 Execution

main.c - Initialize the ATWINC15x0/ATWINC3400 and connect to the AP as a station.

  1. Code summary:
    • Configure the network parameters in main.h.
      /** Wi-Fi Settings */
#define MAIN_WLAN_SSID        "DEMO_AP" /* < Destination SSID */
#define MAIN_WLAN_AUTH        M2M_WIFI_SEC_WPA_PSK /* < Security type */
#define MAIN_WLAN_PSK         "12345678" /* < Password for Destination SSID */
    • Connect the ATWINC15x0/ATWINC3400 to the AP via the m2m_wifi_connect() function.
      /* Connect to defined AP. */
	m2m_wifi_connect((char *)MAIN_WLAN_SSID, sizeof(MAIN_WLAN_SSID), 
                MAIN_WLAN_AUTH, (void *)MAIN_WLAN_PSK, M2M_WIFI_CH_ALL);
    • Call m2m_wifi_req_curr_rssi() to request the current RSSI. 
      
static void wifi_cb(uint8_t u8MsgType, void *pvMsg)
{
    case M2M_WIFI_REQ_DHCP_CONF:
    {
	/* Request RSSI for the connected AP. */
	m2m_wifi_req_curr_rssi();
    • The application will get the RSSI value when the wifi_cb() function is called with a M2M_WIFI_RESP_CURRENT_RSSI message.
      static void wifi_cb(uint8_t u8MsgType, void *pvMsg)
{
    case M2M_WIFI_RESP_CURRENT_RSSI:
    {
	/* This message type is triggered by "m2m_wifi_req_curr_rssi()" function. */
	int8_t *rssi = (int8_t *)pvMsg;
	printf("RSSI for the current connected AP (%d)\r\n", (int8_t)(*rssi));
  2. Build the program and download it into the board.
  3. Start the application.
