ESP32 & Serial.print() and println() are not working at 9600 bauds and 115200

1

Hello,

now I use Serial.print() and Serial.println() at 9600 Bauds, I change the sdkconfig.“project_name”, and I still see strange characters displayed in the serial monitor.

Is there any other config file to change ?

Thank you in advance

Changing the sdkconfig file in an Arduino-ESP32 project? That has no effect, since Arduino-ESP32 is based off a precompiled ESP-IDF version, changes to the sdkconfig file are ignored.

You need to se the monitor_speed value to the baud rate you are using.

If you are still having problems, post the complete platformio.ini and code.
