      When I testing the Sleep mode, my device entering deep sleep mode and disabled USB connection so that I could not write new code into it. Is there any solutions to wake it up? If I can find a serial to USB cable, which port on the devices should I use to connect?

        look at safe boot

        https://docs.pycom.io/gettingstarted/programming/safeboot/#app

        think about people first, then computers

          Maybe it is another problem. I did what the doc said. Holding the safe boot button and restart the device, VS code cannot connect to the device. It just showing 'Connecting to COM3...'. In my device manager, I can see the device is "Port(COM and LPT) USB Serial Device (COM3)". (Something like that since my os is Chinese). 07f85a57-4986-40da-90fb-757ee7c93b72-image.png 107e6eb8-8d98-4a50-a676-f44f51d024f5-image.png
          The LED flashes blue every 5 seconds (heartbeat perhaps).
