I think is useful for everybody this update.
After having checked the info above I have tried again.
This time in the list of COM ports (both in Windows and in Mblock) a new port appeared: COM 17.
So I selected COM 17 and the upload firmware procedure went ok.
But, to prevent and manage future similar issues, for everybody, I think it is better to clarify:
- why, Yesterday, COM 17 did not appear ?
- why the COM 6 port is there? How to remove it?
The COM 17 actually disappears (both in Windows device manager and in Mblock Serial ports list) when I switch the Mbot off (and pop up again when I switch th Mbot on) , then it is defenitely the port of the Mbot
