WiFi/BT and sleep modes
-----------------------
In deep sleep and light sleep modes, wireless peripherals are powered down. Before entering deep sleep or light sleep modes, applications must disable WiFi and BT using appropriate calls (:cpp:func:`esp_bluedroid_disable`, :cpp:func:`esp_bt_controller_disable`, :cpp:func:`esp_wifi_stop`). WiFi and BT connections will not be maintained in deep sleep or light sleep, even if these functions are not called.
In deep sleep and light sleep modes, wireless peripherals are powered down. Before entering light sleep modes, applications must disable WiFi and BT using appropriate calls (:cpp:func:`esp_bluedroid_disable`, :cpp:func:`esp_bt_controller_disable`, :cpp:func:`esp_wifi_stop`). WiFi and BT connections will not be maintained in deep sleep or light sleep, even if these functions are not called.
If WiFi connection needs to be maintained, enable WiFi modem sleep, and enable automatic light sleep feature (see :doc:`Power Management APIs <power_management>`). This will allow the system to wake up from sleep automatically when required by WiFi driver, thereby maintaining connection to the AP.
