BACnet4J is a pure Java implementation of the BACnet specification. Originally developed for supervisory use, it now includes support for many objects and so may be suitable for embedded use as well. Protocols supported include IPv4, IPv6, and MS/TP.
This fork of BACnet4j fixes an issue with the handling of out-of-order segmented messages.

Version 2.0 release notes
The networking package of this product has been pretty much entirely rewritten to support MS/TP. These changes implied many changes to the LocalDevice public interface, so if you were using version 1.x you will need to port some code to upgrade.
This software is licensed under GPL. Commercial licensers can pay an upgrade fee to use this new version (2.x and later) commercially.
