Describe the problem

Upload worked fine, I was testing the Sensirion SEN55 exampleUsage sketch on an adafruit QTPY ESP32-S2. I also have the adafruit wippersnapper sketch open in a first window, but no serial monitor open there.

I had been messing with CDC mode on and off because of seeing no serial monitor output (closed and opened serial monitor). I uploaded multiple times with no problems but never serial monitor entries, despite reboots/reinserts of device and reselecting ports etc. Only when I opened another example sketch in another window to check the i2c bus (adafruit example), then started the compile and upload, switched back to the SEN55 example window and closed the serial monitor, then starting it in the new window did the new window have a working serial monitor showing the SEN55 sketch output, but was almost immediately closed as the upload of the i2c bus example started.

Serial monitor should work reliably. Please investigate using the serial monitor in the second window of a new session, or offer a debug logging build that users with troubles can run and log with.

To reproduce

🤷

Expected behavior

Serial monitor works in any window assuming only a maximum of one serial monitor is open across all windows/sketches.
