I've implemented the 3D People Counting Lab on the IWR6843ISK and have it operating on Windows just fine. In Windows, when I send a config to the device through the Python GUI codebase I can see the ack code responding with a byte array. On a Mac I see something different. The ack code responds with an empty byte array [b''] despite trying to decode() in ascii or utf-8. Is there a trick to getting this working on Mac OS X Catalina with Python 3.7?
