The ping example works fine with stdout but not the tool in question.

I must stress that it is a windows CLI Tool but the beauty of subprocess is that it is cross platform.
Is there anything to consider if its windows?
Did you try to set
stderr=subprocess.STDOUT? Some apps send output to stderr - don't ask me why, but I saw it happening, especially with HW-oriented apps.One more thing I have forgotten (I haven't used
subprocess for several months) - by default its output is bytestrings, universal_newlines=True forces its output to unicode strings.If you run your command in terminal, does it provide continuous output - or only after you stop it? In the former case, my approach should work
Test everything in a Python shell (iPython, Azure Notebook, etc.)
