 The PHY initialization data is used for RF calibration.
 There are two ways to get the PHY initialization data.
 
-.. only:: esp32

-    One is the default initialization data which is located in the header file :idf_file:`components/esp_wifi/esp32/include/phy_init_data.h`.

+One is the default initialization data which is located in the header file :idf_file:`components/esp_wifi/esp32/include/phy_init_data.h`.
 
 It is embedded into the application binary after compiling and then stored into read-only memory (DROM).
 To use the default initialization data, please go to ``menuconfig`` and disable :ref:`CONFIG_ESP32_PHY_INIT_DATA_IN_PARTITION`.
