LOPY4 module getting "Failed to Connect"

by Theivanand on Wed Jun 10, 2020 4:07 am

Hi,

Im new to MicroPython and PYCOM stuff.
I have been trying to connect to LOPY4 but somehow I'm getting below error:

Connecting to COM6...
> Failed to connect (Error: Port is not open).

I'm using Expansion Board V3 together with LOPY4.
I have upgraded firmware for Expansion Board and also LOPY4.
I'm stuck to move forward.
Please do assist.

Thanks.

I am not personally familiar with the LOPY4, however your error sounds like the code you are using expects on COM port to be open when it might need to be looking for a different name.

I would suggest taking a good look at the documentation available here:
