That does not sound like a Nano33 IoT. So which board do you actually use?
BN: Unknown board
VID: 10C4
PID: EA60
SN: Upload any sketch to obtain it
Definitely not an Arduino Nano33 IoT and hence your topic has been moved.
Please post your sketch; don't forget to use code tags (you did it right in the opening post 
)
Please provide links to any libraries that you use that are not available though library manager.
