Python Bridge - Calling HV via subprocess.Popen

Recommended Posts

I would like to use python subprocess module to invoke HV.
The code I use is very simple.
The code works if I use standalone python, but if I run it from within Compose, HW does not come up.

In the Task Manager one can see, that the HW Process starts but also dies immediately.

Here's the code that I use:

The shell shows the commands used in the directly in python.

 

I have also attached the Python file.

Have I missed anything?

hwCall.py
