Not able to create local device using port 47809
-
Hi,
With BACnet4J library, I am trying to create a new object of the local device using port 47809 and initialize it.
Code snippet::static LocalDevice initializeLocalDevice() {
LocalDevice device = null;
try {
device = new LocalDevice(localDeviceId, new DefaultTransport(new IpNetworkBuilder().withPort(47809).build()));
device.initialize();
} catch (Exception e) {
System.err.println("Error in initializeLocalDevice: " + e);
e.printStackTrace();
}
return device;
}But, got below error while executing the above code.
Error:
Error in initializeLocalDevice: java.lang.IllegalArgumentException: Either withBroadcast or withSubnet must be called.
java.lang.IllegalArgumentException: Either withBroadcast or withSubnet must be called.
at com.serotonin.bacnet4j.npdu.ip.IpNetworkBuilder.build(IpNetworkBuilder.java:129)Please provide any solution for the same.
Thanks,

Hi Vihangi, welcome to the forum.
The answer is right there in the exception. If you're going to be developing with BACnet4J you will need to be able to read in the code why the exception has occurred if its message is not clear to you: https://github.com/infiniteautomation/BACnet4J/blob/master/src/main/java/com/serotonin/bacnet4j/npdu/ip/IpNetworkBuilder.java#L128

Hi Phildunlap, Thanks for the reply.
My error is resolved by doing below changes:
new DefaultTransport(new IpNetworkBuilder().withPort(47809).withBroadcast(broadcastAdd, 24).build()Can we implement BACnet router to do communication between two devices with the different ports?
For example:
One device with port 47808 and another one with 47809Is it possible to do this with BACnet4J library?
-
Per the BACnet specification all devices on a network must be on the same port. So, to bridge networks you need a BBMD, which could be a BACnet router. The IpNetwork class does have support for behaving as a BBMD, but as Mango does not expose this functionality I have little experience with it. You can see there is an enableBBMD method, though: https://github.com/infiniteautomation/BACnet4J/blob/master/src/main/java/com/serotonin/bacnet4j/npdu/ip/IpNetwork.java#L991

As I want to poll and read trend logs. -
Did you attempt to figure this out before you asked? Are you attempting to read the log buffer property? https://github.com/infiniteautomation/BACnet4J/blob/master/src/main/java/com/serotonin/bacnet4j/obj/TrendLogObject.java#L233
-
Yes, I have tried to trigger it and it will work. But, with " logging-type Value = polled", it was not able to get a trend log.
With polling, it will generate below error:
ErrorAPDU(errorClass=property, errorCode=invalid-data-type,errorClass=property, errorCode=invalid-data-type) Error: ErrorAPDU(errorClass=property, errorCode=invalid-data-type,errorClass=property, errorCode=invalid-data-type), originalInvokeId=18Read the output of log buffer property:
Error: ErrorAPDU(errorClass=property, errorCode=read-access-denied,errorClass=property, errorCode=read-access-denied)Is there any configuration issue?
-
Still not able to read Log buffer values.
Got same Error:
ErrorAPDU(errorClass=property, errorCode=invalid-data-type,errorClass=property, errorCode=invalid-data-type) Error: ErrorAPDU(errorClass=property, errorCode=invalid-data-type,errorClass=property, errorCode=invalid-data-type), originalInvokeId=18Please help me with this.
