how to enable ESP32 idf UART console function and make the esp32 get same input from UART

[wziy520]

btw, Which file defined the CONFIG_CONSOLE_UART_NUM value?

When we use the ESP-IDF build environment, a file called "sdkconfig.h" is generated once we run "make menuconfig". This file should be (opinion/experience) included in all your source files. It contains all the properties defined by the configurator as C macro definitions.
