-    In Deep-sleep and Light-sleep modes, the wireless peripherals are powered down. Before entering Deep-sleep or Light-sleep modes, the application must disable Wi-Fi and Bluetooth using the appropriate calls (i.e., :cpp:func:`esp_bluedroid_disable`, :cpp:func:`esp_bt_controller_disable`, :cpp:func:`esp_wifi_stop`).

 如需保持 Wi-Fi 连接，请启用 Wi-Fi Modem-sleep 模式和自动 Light-sleep 模式（请参阅 :doc:`电源管理 API <power_management>`）。在这两种模式下，Wi-Fi 驱动程序发出请求时，系统将自动从睡眠中被唤醒，从而保持与 AP 的连接。
