the problem is that I cannot read anything on the serial monitor, so I suppose the device is not working correctly.
Sparkfun reply to the post I made on their forum. They saw the youtube video and said:
"Try closing the other Arduino window; also that qwiic cable is pretty long which can create too high of resistance (in some cases); do you have a shorter one you can try?
I would also recommend removing the double-adapter thing going to the laptop's usb and trying just a simple usb-micro to usb-A cable"
So I tried a new direct cable, a shorter cable, closing the window, but the problem is still there...
If I unplug the qwiic cable the program says "Device did not acknowledge! Freezing", so I suppose the sensor is detected...
Tryed on a MACbook PRO Ventura and a Windows 11 PC with the same results...
