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"
depends on SOC_WIFI_SUPPORTED
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'.

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.

help
Absolute path, or path relative to the project directory, to the file
phy_multiple_init_data.bin, or to a directory containing that file.
If this field is left empty, or the file cannot be found at the resolved path,
the default binary located at components/esp_phy/<chip>/phy_multiple_init_data.bin
will be used.
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)"

Set maximum transmit power for WiFi radio. Actual transmit power for high
data rates may be lower than this setting.

bool "Power down MAC and baseband of Wi-Fi and Bluetooth when PHY is disabled"
depends on SOC_PM_SUPPORT_MAC_BB_PD && 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 ESP_BROWNOUT_DET

help
When brownout reset occurs, reduce PHY TX power to keep the code running.

default y if IDF_TARGET_ESP32C3 || IDF_TARGET_ESP32S3 \

default n
help
On some ESP targets, the USB PHY can interfere with WiFi thus lowering WiFi performance.
As a result, on those affected ESP targets, the ESP PHY library's initialization will automatically
disable the USB PHY to get best WiFi performance.
This option controls whether or not the ESP PHY library will keep the USB PHY enabled on
initialization.
Note: This option can be disabled to increase WiFi performance. However, disabling this option will
also mean that the USB PHY cannot be used while WiFi is enabled.
config ESP_PHY_ENABLE_CERT_TEST
bool "Enable RF certification test functions"

help
If enabled, you can use RF certification test APIs.
choice ESP_PHY_CALIBRATION_MODE

default ESP_PHY_RF_CAL_PARTIAL
help
Select PHY calibration mode. During RF initialization, the partial calibration
method is used by default for RF calibration. Full calibration takes about 100ms
more than partial calibration. If boot duration is not critical, it is suggested
to use the full calibration method. No calibration method is only used when the
device wakes up from deep sleep.

This is a workaround to improve Wi-Fi receive 11b pkts for some modules using AC-DC power supply with
high interference, enable this option will sacrifice Wi-Fi OFDM receive performance.
But to guarantee 11b receive performance serves as a bottom line in this case.

help
Select this option to place frequently called PHY library functions in IRAM.
When this option is disabled, more than 1.1Kbytes of IRAM memory will be saved,
but PHY performance will be reduced. This config only affect esp32c2 now.
menuconfig ESP_PHY_DEBUG
bool "Enable PHY Debug"

Enabling this option allows different kinds of phy debugging features.
config ESP_PHY_DISABLE_PLL_TRACK

help
Disable pll track. This configuration option is used for experimental.
PLL track helps the PHY module adapt to temperature changes, ensuring stable performance.
When pll enabled, the ESP PHY module will periodically track and adjust PLL parameters.
