+Bluetooth Common
+====================

+:link_to_translation:`zh_CN:[中文]`

+The following Bluetooth Common header declarations have been moved:

 .. only:: esp32
 
     - :component_file:`/bt/include/esp32/include/esp_bt.h`
 
+        - Move the declarations of ``esp_wifi_bt_power_domain_on`` and ``esp_wifi_bt_power_domain_off`` from ``esp_bt.h`` to ``esp_phy_init.h``, since they belong to component ``esp_phy`` and are not expected to be used by customer.
