Wi-Fi/Bluetooth and Sleep Modes
---------------------------------
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`). Wi-Fi and Bluetooth connections will not be maintained in Deep-sleep or Light-sleep mode, even if these functions are not called.

睡眠模式下的 Wi-Fi 功能
--------------------------
在 Light-sleep 和 Deep-sleep 模式下，无线外设会被断电。因此，在进入这两种睡眠模式前，应用程序必须调用恰当的函数 (:cpp:func:`esp_wifi_stop`) 来禁用 Wi-Fi。在 Light-sleep 或 Deep-sleep 模式下，即使不调用此函数也无法连接 Wi-Fi。
在 Light-sleep 和 Deep-sleep 模式下，无线外设会被断电。因此，在进入 Light-sleep 模式前，应用程序必须调用恰当的函数 (:cpp:func:`esp_wifi_stop`) 来禁用 Wi-Fi。在 Light-sleep 和 Deep-sleep 模式下均无法保持 Wi-Fi 的连接。
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。
