config ESP_PHY_CALIBRATION_AND_DATA_STORAGE
bool "Store phy calibration data in NVS"
default y
help
If this option is enabled, NVS will be initialized and calibration data will be loaded from there.
PHY calibration will be skipped on deep sleep wakeup. If calibration data is not found, full calibration
will be performed and stored in NVS. Normally, only partial calibration will be performed.
If this option is disabled, full calibration will be performed.
If it's easy that your board calibrate bad data, choose 'n'.
Two cases for example, you should choose 'n':
1.If your board is easy to be booted up with antenna disconnected.
2.Because of your board design, each time when you do calibration, the result are too unstable.
If unsure, choose 'y'.
menuconfig ESP_PHY_INIT_DATA_IN_PARTITION
bool "Use a partition to store PHY init data"
default n
help
If enabled, PHY init data will be loaded from a partition.
When using a custom partition table, make sure that PHY data
partition is included (type: 'data', subtype: 'phy').
With default partition tables, this is done automatically.
If PHY init data is stored in a partition, it has to be flashed there,
otherwise runtime error will occur.
If this option is not enabled, PHY init data will be embedded
into the application binary.
If unsure, choose 'n'.
config ESP_PHY_DEFAULT_INIT_IF_INVALID
bool "Reset default PHY init data if invalid"
default n
depends on ESP_PHY_INIT_DATA_IN_PARTITION
help
If enabled, PHY init data will be restored to default if
it cannot be verified successfully to avoid endless bootloops.
If unsure, choose 'n'.
if ESP_PHY_INIT_DATA_IN_PARTITION
config ESP_PHY_MULTIPLE_INIT_DATA_BIN
bool "Support multiple PHY init data bin"
depends on ESP_PHY_INIT_DATA_IN_PARTITION
default n
help
If enabled, the corresponding PHY init data type can be automatically switched
according to the country code. China's PHY init data bin is used by default.
Can be modified by country information in API esp_wifi_set_country().
The priority of switching the PHY init data type is:
1. Country configured by API esp_wifi_set_country()
and the parameter policy is WIFI_COUNTRY_POLICY_MANUAL.
2. Country notified by the connected AP.
3. Country configured by API esp_wifi_set_country()
and the parameter policy is WIFI_COUNTRY_POLICY_AUTO.
config ESP_PHY_MULTIPLE_INIT_DATA_BIN_EMBED
bool "Support embedded multiple phy init data bin to app bin"
depends on ESP_PHY_MULTIPLE_INIT_DATA_BIN
default n
help
If enabled, multiple phy init data bin will embedded into app bin
If not enabled, multiple phy init data bin will still leave alone, and need to be flashed by users.
config ESP_PHY_INIT_DATA_ERROR
bool "Terminate operation when PHY init data error"
depends on ESP_PHY_MULTIPLE_INIT_DATA_BIN
default n
help
If enabled, when an error occurs while the PHY init data is updated,
the program will terminate and restart.
If not enabled, the PHY init data will not be updated when an error occurs.

config ESP_PHY_MAX_WIFI_TX_POWER
int "Max WiFi TX power (dBm)"
range 10 20
default 20
help
Set maximum transmit power for WiFi radio. Actual transmit power for high
data rates may be lower than this setting.
config ESP_PHY_MAX_TX_POWER
int
default ESP_PHY_MAX_WIFI_TX_POWER
config ESP_PHY_MAC_BB_PD
bool "Power down MAC and baseband of Wi-Fi and Bluetooth when PHY is disabled"
depends on ((IDF_TARGET_ESP32C3 || IDF_TARGET_ESP32S3) && FREERTOS_USE_TICKLESS_IDLE)
default n
help
If enabled, the MAC and baseband of Wi-Fi and Bluetooth will be powered
down when PHY is disabled. Enabling this setting reduces power consumption
by a small amount but increases RAM use by approximately 4 KB(Wi-Fi only),
2 KB(Bluetooth only) or 5.3 KB(Wi-Fi + Bluetooth).
config ESP_PHY_REDUCE_TX_POWER
bool "Reduce PHY TX power when brownout reset"
depends on ESP32_BROWNOUT_DET
default y
help
When brownout reset occurs, reduce PHY TX power to keep the code running.
config ESP_PHY_ENABLE_USB
bool "Enable USB when phy init"
depends on USB_OTG_SUPPORTED || ESP_CONSOLE_USB_SERIAL_JTAG || ESP_CONSOLE_SECONDARY_USB_SERIAL_JTAG
default y if IDF_TARGET_ESP32C3 || IDF_TARGET_ESP32S3
default n
help
When using USB Serial/JTAG/OTG/CDC, PHY should enable USB, otherwise USB module
can not work properly. Notice: Enabling this configuration option will slightly impact wifi performance.
