3.1.8.1 Execution

main.c - Initialize the ATWINC15x0, set PS Mode and get the RSSI for the connected AP.

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 manner */
#define MAIN_WLAN_PSK         "12345678" /* < Password for Destination SSID */

Configure the Power Save parameters in main.h.

/** PowerSave mode Settings */
#define MAIN_PS_SLEEP_MODE          M2M_PS_MANUAL /* M2M_NO_PS / M2M_PS_DEEP_AUTOMATIC / M2M_PS_MANUAL */

In the main() function, set the Power Save mode, based on the define above.

/* Set defined sleep mode */
	if (MAIN_PS_SLEEP_MODE == M2M_PS_MANUAL) {
		printf("M2M_PS_MANUAL\r\n");
		m2m_wifi_set_sleep_mode(MAIN_PS_SLEEP_MODE, 1);
	} else if (MAIN_PS_SLEEP_MODE == M2M_PS_DEEP_AUTOMATIC) {
		printf("M2M_PS_DEEP_AUTOMATIC\r\n");
		tstrM2mLsnInt strM2mLsnInt;
		m2m_wifi_set_sleep_mode(M2M_PS_DEEP_AUTOMATIC, 1);
		strM2mLsnInt.u16LsnInt = M2M_LISTEN_INTERVAL;
		m2m_wifi_set_lsn_int(&strM2mLsnInt);
	}

Connect to the AP.

/* 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);

The ATWINC15x0 goes to Sleep automatically if Power Save is configured for the M2M_PS_DEEP_AUTOMATIC mode. The ATWINC15x0 will wake up upon any request/callback (Wi-Fi/SOCKET) and the host driver will allow the SoC to sleep again after handling the request. However, if Power Save is configured for the M2M_PS_MANUAL mode, then the application is responsible for explicitly requesting the ATWINC15x0 to enter sleep while specifying the expected sleep time.
```
/* Request sleep mode */
if (gu8SleepStatus == MAIN_PS_REQ_SLEEP) {
	if (MAIN_PS_SLEEP_MODE == M2M_PS_MANUAL) {
		m2m_wifi_request_sleep(MAIN_REQUEST_SLEEP_TIME);
		gu8SleepStatus = MAIN_PS_SLEEP;
	}
}
```

Build the program and download it into the board.
Start the application.
