What is the best/recommended way to take a wireshark-dump in this case

The best way is using a tap. If you don't have one, use a managed switch with a port mirror. If you don't have this one either, start development in small steps: make sure a simple ping works first by connecting your device 1:1 to your PC. Then start using UDP, then TCP. Check small *and* large frames are working without errors.
