    help
        This option allows configuring the desired line endings sent to UART
        when a newline ('\n', LF) appears on stdout.
        Three options are possible:

        CRLF: whenever LF is encountered, prepend it with CR

        LF: no modification is applied, stdout is sent as is

        CR: each occurence of LF is replaced with CR

        This option doesn't affect behavior of the UART driver (drivers/uart.h).

        Enable this option, full 32 KB iram instead of 16 KB iram will be used as icache, so the heap use can use
        may reduce a lot.

        Function "esp_wifi_scan_get_ap_num" return value will be less than this. It is said that user cannot
        scan more than this.

        User can use own function "esp_wifi_scan_get_ap_num_max" to determin how many AP to scan , too.

        If this option is enabled, Wifi will try to send packets first from high rate(54M). If it fails, it will 
        try at low rate until the transmission is successful.

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'.

config 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'.
