----------------------- -----------------------
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.
