What is the expected behavior?

I'm using esp_deep_sleep_start() and esp_sleep_enable_timer_wakeup() to make the device enter deep-sleep.

When the device awakened from deep-sleep, it will use esp_wifi_scan_start() to scan APs.

What is the actual behavior?

When the device booted from POWERON, it can normally get the APs.

However, when it restarted from DSLEEP, it can't get any AP.

Steps to reproduce.

void enter_sleep(uint32_t time_ms)
{
    esp_sleep_enable_timer_wakeup(time_ms * 1000);
    esp_deep_sleep_start();
}

void wifi_sta_init()
{
    ESP_ERROR_CHECK(esp_netif_init());
    ESP_ERROR_CHECK(esp_event_loop_create_default());
    wifiHandle = esp_netif_create_default_wifi_sta();

    wifi_init_config_t cfg = WIFI_INIT_CONFIG_DEFAULT();
    ESP_ERROR_CHECK(esp_wifi_init(&cfg));

    ESP_ERROR_CHECK(esp_wifi_set_mode(WIFI_MODE_STA));
    ESP_ERROR_CHECK(esp_wifi_start());
}

void wifi_scan()
{
       uint16_t sta_number = 0;
    wifi_ap_record_t ap_list[MAX_SCAN_LIST_SIZE];

    // 开始扫描
    esp_wifi_scan_start(NULL, true);

    esp_wifi_scan_get_ap_num(&sta_number);
    sta_number = sta_number > MAX_SCAN_LIST_SIZE ? MAX_SCAN_LIST_SIZE : sta_number;

    memset(ap_list, 0, sizeof(ap_list));
    memset(&m_scan_list, 0, sizeof(m_scan_list));
    if (esp_wifi_scan_get_ap_records(&sta_number, ap_list) == ESP_OK)
    {
        for (uint16_t i = 0; i < sta_number; i++)
        {

            if (strlen((char *)ap_list[i].ssid) >= MAX_SSID_LENGTH)
            {
                continue;
            }
            strcpy(m_scan_list.item[m_scan_list.num].ssid, (char *)ap_list[i].ssid);
            m_scan_list.item[m_scan_list.num].authmode = ap_list[i].authmode;
            m_scan_list.item[m_scan_list.num].rssi = ap_list[i].rssi;
            m_scan_list.item[m_scan_list.num].channel = ap_list[i].primary;
            m_scan_list.num++;
        }

        printf("sta_number:%d\r\n",m_scan_list.num);
    }
    return &m_scan_list;
}

void main()
{
     wifi_sta_init();
     wifi_scan();
     enter_sleep(5000);
}
