Thank you.
But the content of the link says it relates java option matter, it seems doubtful a little for me about it.
I'll try it anyway.

Thank you for your answering.
I realized that instaceId == deviceId ,later.
I could do what I want as below.
RemoteDeviceFuture dd = localDevice.getRemoteDevice(instaceId );
RemoteDevice d = dd.get();
The bug what I got seems being resolved with getRemoteDevice() of Bacnet4J 4.X.
thank you.

@ssimm This is a limitation of the BACnet protocol. All devices must be on the same UDP port (47808 default).

I manually downloaded all the missing jars from the repo you provided and it seems to be working now apart from

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".

But I get no exceptions when calling

dev.initialize();

Thanks for the help.

Hi Gonzalo, welcome to the forum!

I'm not sure what you mean. There is a jar in any Mango BACnet module in its lib directory. Perhaps you are asking about the releases here? https://github.com/infiniteautomation/BACnet4J/releases

No, there doesn't appear to be a jar file linked in that release, you would have to build it yourself. Our build system doesn't trigger BACnet4J builds automatically, but I just hit the build button on the current state of the repo: https://maven.mangoautomation.net/#browse/browse/assets:ias-snapshot:9238f1f3c81af9d8ce43f83c0a18ec70

Thank you for the reply. But still i have some unresolved questions.

My objective is to get bacnet devices list in a network and to get the objects and its properties. Which file should i run in the Bacnet4J library to get these results? Is there any test file available in the library to get this?
Your help is highly appreciated since there is no help available on internet

Hello Phildunlap,

Thank you very much for your quick response. Much appreciated !!

I got your point, will check on those two APIs over this weekend and let you know whether I'm able to find a solution.

Thank you very much.

The Timer in LocalDevice which handles the COV tasks and whatnot is created without a minimum pool size and with Integer.MAX_VALUE as the upper bound.

The "withLocalNetworkNumber" function, https://github.com/infiniteautomation/BACnet4J/blob/master/src/main/java/com/serotonin/bacnet4j/npdu/ip/IpNetworkBuilder.java

Great!

Hmm, I'm not sure. You could try doing a ReadPropertyRequest for the present value, instead of trying to get the whole Object.

Hi cenk,

I'm not sure precisely what you mean, but, you can issue a request to it and see if it responds.

Hi gadi.alaloof,

I think this thread might be similar: https://forum.infiniteautomation.com/topic/3121/unable-to-discover-a-bacnet-device-on-my-network/18

The resolution there was found in using a local bind address of 0.0.0.0 and a broadcast address particular to the network, like 192.168.1.255 for the 192.168.1.0/24 network. BACnet local device settings are on the /system_settings.shtm page

@phildunlap said in BACnet string point:

BACnet module 3.3.1 is released!

Thanks

I found a solution, although it's not ideal.

If you disable communications via LocalDevice.setCommunicationControl after having subscribed, you get the behavior I'm looking for. This seems a bit heavy-handed when all I want to do is turn off acknowledgment for a single service, but it will do for the time being until someone shows me a better way.

Hi Wingnut,

I don't believe it is currently possible. I looked around the code a little, and I think it's SubscribeCOVRequest that is the outgoing form used, and it doesn't have these options. I imagine it's something we're interested in supporting, but have no sense of a timeline to offer offhand. Doesn't seem like it would be too much to add, but I can't say.

Great! Hope that does what you need.

Pretty much any time the script is going through Java code to do something, it'll happen during validation or actual runtime the same. Things like the RuntimeManager, JsonEmport or calling the set() function will only actually change things if running, since they're going through mechanisms particular to the scripts.
