WiFi/BT and sleep modes
-----------------------
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.
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:`nimble_port_stop`, :cpp:func:`nimble_port_deinit`, :cpp:func:`esp_bluedroid_disable`, :cpp:func:`esp_bluedroid_deinit`, :cpp:func:`esp_bt_controller_disable`, :cpp:func:`esp_bt_controller_deinit`, :cpp:func:`esp_wifi_stop`). Wi-Fi and Bluetooth connections are not maintained in Deep-sleep or Light-sleep mode, even if these functions are not called.
If Wi-Fi/Bluetooth connections need to be maintained, enable Wi-Fi/Bluetooth Modem-sleep mode and 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 the Wi-Fi/Bluetooth driver, thereby maintaining the connection.
