通过uart的esp32 printf通道（esp-idf）

Question

I try to disable all logs on my program, I did disable esp logs but when I use printf in my channel and open make monitor printf still works.

how and why? I want to disable it.

Answer 1

The system logs and printf are two different things over here. In your project sdkconfig file check if the parameter ' CONFIG_CONSOLE_UART_DEFAULT ' is set.

This defines where all your console outputs are dumped into.

In your case you want to disable all the printf logs, you can try setting ' CONFIG_CONSOLE_UART_NONE =y'.

If you are doing it thourgh make menuconfig of esp-idf, it will come under - component config > ESP32-Specific > UART for console output (Default: UART0, TX=GPIO1, RX=GPIO3) > None

Hope I answered to your question. :)
