Searching for WiFi shield doesn't work on machines with multiple network interfaces

[dyfer]

When searching using service discovery, the HUB doesn't find WiFi shields connected to a secondary network interface. Tested with OpenBCI_GUI app version 3.3.2.

In this scenario connecting to the shield by IP still works fine, only searching doesn't.

I reported similar issue for the Python library as well, linking to the fix. The fix involved explicitly broadcasting multicast messages on all network interfaces. Not sure how to fix this here.

I encountered this issue on Windows machine with a virtual box. A fix was implemented to look for "Ethernet" or "WiFi" network interface and use that.
