No device found on COM1

Products & Technology Wio Terminal

I can’t seem to get my Wio Terminal working or recognized by the Arduino Software. I am getting no device found on COM1. Other microcontrollers work on this USB port and the Wio Terminal was working before I put it away for a few months. The green and blue lights appear to be working. Below is the error message I am getting from the Arduino IDE.

Arduino: 1.8.13 (Windows 10), Board: “Seeeduino Wio Terminal, Enabled, 120 MHz (standard), Small (-Os) (standard), 50 MHz (standard), Arduino, Off”

Sketch uses 97176 bytes (19%) of program storage space. Maximum is 507904 bytes.

An error occurred while uploading the sketch

No device found on COM1

This report would have more information with
“Show verbose output during compilation”
option enabled in File -> Preferences.

Hi @laefsky,

Could you first reset Wio Terminal and then try to upload the code again?

If reset doesn’t work, enter bootloader mode, and try to upload the code again.

Note: When you enter bootloader mode, the COM port changes. So you have to go to Tools > Port and change the COM port.

The instructions can be found in the link below:

Hope it works!

Best Regards,
Lakshantha
