OSError: [Errno 22] Invalid argument

[Raphtor]

I am getting an OSError when running the example. It evidently can see the server, but can't open the socket?

python3 natnet-client-demo.py --server 192.168.0.100

That sounds like a problem with your network interface: https://stackoverflow.com/questions/19403635/python-setsockopt-invalid-argument-with-ip-add-membership

Do the official SDK samples work on your machine?
