Hi,
Indeed, in case of Windows you only need to try the bluegiga way. So the error you see is irrelevant on Windows. You need to concentrate on BLED112. I myself don't have Windows nor BLED112, so I can only guess.
First thing to do, is instead of automatic connection, use hub=MoveHub(get_connection_bluegiga()) always, so you won't get irrelevant messages. Then, to get potentially more diagnostics, add import logging; logging.basicConfig(level=logging.DEBUG); before getting MoveHub connection.
Please share the results here.

Hi Andrey,
I changed the logging and the initialization of the MoveHub as suggested. This changed the error message:

Then I started debugging with some breakpoints in bgapi.py, serialwin32.py, cpygatt.py etc - and without changing the code or any variables, the connection was working fine afterwards...

So I have the feeling this is an issue in the related libraries for the BLE/socket/COM communication...
