Wio Lite W600: Serial Errors

Hi all,

I just got a Wio Lite W600, and I’m having trouble connecting via serial. I have it plugged into my computer via USB C, and when I do either screen /dev/ttyACM0 9600 or wio monitor /dev/ttyACM0, I see error messages such as the following:

Wio Serial Monitor  @  /dev/ttyACM0  @  9600
--- Quit: Ctrl+C ---

At some point, I noticed that it was spelling out my wifi network SSID one letter per line immediately before 16......23, so it seems to be functioning at least a little bit.

I noticed that someone else on Amazon had similar errors.

If anyone has any advice on these errors, I’d love to hear it. Or if you can point me to some error code documentation that explains what’s going wrong, that would also be great,

Thanks!

I was able to successfully follow the instructions in the wiki to program the board with the log_data example. My requests are being sent correctly, and the serial monitor now shows logs of the requests with no more errors.

I guess it’s good to read the instructions first :wink:
