XIAO ESP32S3 Touch Problem


I was trying the XIAO ESP32S3 touch examples and looks like the readings will freeze after the touch pin is grounded. I tried both Arduino IDE examples and IDF examples, same problem.

Does anyone know how to fix this? Or is there a way to “reset” the touch function without resetting the whole system, so that the touch function could still be used after ground is detached from touch pin?

I have tried other ESP32 boards(WROOM) and this does not seem to happen.

Thank you
