Reading Site level and Group level objects using BACnet4j

[ghost]

Hi Folks,

I am trying to read Objects and Properties from BACnet interface. We are using example code of BACnet4J where our client code is expected to communicate with BACnet interface provided by LumInsight Desktop(Propriety Software).

So, in our case the device discovery is complete but we are stuck in how to read Site level and Group level information from BACnet interface.

Here is the output I am getting currently:

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder". SLF4J: Defaulting to no-operation (NOP) logger implementation SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details. initialized Printing address...Address [networkNumber=0, macAddress=[a,2c,37,5,ba,c0]] RemoteDevice(instanceNumber=10001, address=Address [networkNumber=0, macAddress=[a,2c,37,5,ba,c0]]) ObjectIdentifier:Device 10001 getName:LumInsight Virtual Router getModelName:LIBI-01 Remote Device:RemoteDevice(instanceNumber=10001, address=Address [networkNumber=0, macAddress=[a,2c,37,5,ba,c0]]) User data: device retrieved:[Device 10001] property values: PropertyValues [values={ObjectPropertyReference(objectIdentifier=Device 10001, propertyIdentifier=presentValue, propertyArrayIndex=null)=errorClass=Property, errorCode=unknownProperty}] errorClass=Property, errorCode=unknownProperty

The source code which I am referring and modified is as below:
