2. ...

// It helps if you attach a picture of your setup/wiring here.

Code to reproduce this issue

// the code should be wrapped in the ```cpp tag so that it will be displayed better.
#include "esp_log.h"

void app_main()
{

}

// If your code is longer than 30 lines, GIST is preferred.

Debug Logs

Debug log goes here, should contain the backtrace, as well as the reset source if it is a crash.
Please copy the plain text here for us to search the error log. Or attach the complete logs but leave the main part here if the log is *too* long.

Other items if possible

• [ ] sdkconfig file (attach the sdkconfig file from your project folder)
• [ ] elf file in the build folder (note this may contain all the code details and symbols of your project.)
• [ ] coredump (This provides stacks of tasks.)
