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 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.

If the modem sleep mode is enabled, bluetooth will switch periodically between active and sleep.
In sleep state, RF, PHY and BB are turned off in order to reduce power consumption.

This example contains some build configurations. For each configuration, a few configuration options are set:
- `sdkconfig.defaults.esp32`: ESP32 uses 32kHz XTAL as low power clock in light sleep enabled.
- `sdkconfig.defaults.esp32c3`: ESP32C3 uses 32kHz XTAL as low power clock in light sleep enabled.
- `sdkconfig.40m.esp32c3`: ESP32C3 uses main XTAL as low power clock in light sleep enabled.
