Can't find device on an enterprise network

[antucg]

Hi, I am using this library in my Android project. It works ok at home, one device can find another without any problems. It is fast an reliable. The problem is when I try in the office where I work, or the university. These networks are more complex (obviously). In this case, the device that looks for the services, can find nothing. I wait a while, but nothing comes up. I guess that either some ports are blocked or firewall configuration is blocking something, who knows. I don't have access to any info about the infrastructure. My question is, is there any workaround that can help me with this issue? Or is there an alternative to this library that might work in a different way and might not cause this problem?

Thanks.

Hi, I guess more information needed. Try to write all logs to some file.
Also, I can recommend you try to find any services with Service Browser in your university network

There are no logs, it will start browsing but it doesn't find anything. Apparently it is due to security implemented on big networks. So the idea is to implement a different system for this scenario. Just to clarify, the problem is not with the lib, but with the procotol. As it relies in broadcast most of big networks infrastructure block it for security reasons.
