I need to implement a java application that reads bacnet devices properties. the "devices" are created by a 3rd party application that runs on the same machine.

I've seen many Bacnet explorers that shows BACNet elements that are running an the same machine - I wonder if this is possible with BAC4J

In bac4J when i try to create a local device I get an exception of port in use error.
Is it possible to connect to an existing network in the same machine?
