OSC Data Monitor
You can use the OSC Data Monitor to quickly check if you have communication with OSC (Open Sound Control) sending equipment in your network.
The tool is open-source and built in Processing (get it on Github). You can actually run in it directly in Processing, when you install the needed libraries.
MacOS
For the ease of use I (with the help of Daan Nijkamp) made a signed version for MacOs, so you can use it on any system without too much hassle. There is a version for Apple Silicon and a version for Apple Intel.
Windows
A Windows build is also included, although it's not signed. You'll get a dialog that "Windows protect your PC", press "More Info" and click "Run Anyway".
I hope it helps you with the testing and debugging of your OSC setup.
See http://www.kasperkamperman.com/blog/osc-datamonitor/ for a video walkthrough and other information about OSC.
