Hi, we currently use BACnet4J on our bachelor internship project. Yesterday or so we figured out it didn't already support proper priority handling which kind of upset our customer ;). As we're on a tight schedule for delivery I was relieved to see someone requested this the beginning of this year and you delivered! A big thanks for that one ;D
So still we wonder why OutOfService is not supported, yet (any pitfalls associated?)? We're going to implement that on ourself for now (see tight schedule == first version on friday).
But above all I want to thank you for your great work you've done and are doing here!
