My questions:
Does the Focus 3 support UDP broadcasts at all?
If so, how do we enable it?
If it is enabled but still not working, is it possibly a C# UdpClient issue on the Focus 3? Or is it a Unity thing?
We are working in Unity, and have custom C# networking libraries (based on UdpClient) that we've used in Windows-based products for years. This code relies on UDP broadcasts for some features to work properly. Using these libraries in an Android build, the Focus 3 is able to send broadcast messages but does not receive them. I have searched the topic of UDP broadcasts on Android extensively, and applied all of the changes found, but it's still not working. I did run into one forum thread where it was found that the kernel for a particular phone did not support broadcasts. That made me wonder if that's what is happening here. Does the Focus 3 support receiving UDP broadcasts?
