<![CDATA[PropertyArrayIndex=null with SlaveDeviceTest]]>I have downloaded and run bacnet4J 1.2, then I have tried to run the SlaveDeviceTest together with the DiscoveryTest. Of course, I have adjusted the IP address.
This is my output:


IAm receivedRemoteDevice(instanceNumber=1968, address=Address(networkNumber=0, macAddress=[a,1,a,47,8,14]), network=null)
ObjectPropertyReference(objectIdentifier=Analog Input 0, propertyIdentifier=Object name, propertyArrayIndex=null)
ObjectPropertyReference(objectIdentifier=Analog Input 0, propertyIdentifier=Units, propertyArrayIndex=null)
ObjectPropertyReference(objectIdentifier=Analog Input 0, propertyIdentifier=Present value, propertyArrayIndex=null)
RemoteDevice(instanceNumber=1968, address=Address(networkNumber=0, macAddress=[a,1,a,47,8,14]), network=null)

This is my code on SlaveDeviceTest


        BACnetObject ai0x = new BACnetObject(localDevice,
                localDevice.getNextInstanceObjectIdentifier(ObjectType.analogInput));
        ai0x.setProperty(PropertyIdentifier.objectName, new CharacterString("AAAAAaaaaAAAA"));
        ai0x.setProperty(PropertyIdentifier.units, EngineeringUnits.centimeters);
        localDevice.addObject(ai0x);

My question is: why is the propertyArray null? Shouldn't it contain my values instead?

Thanks.

The code posted prints the reference instead of the actual values...

Please let me know how to rectify this, thanks.

ai0x.setProperty(PropertyIdentifier.objectName, new CharacterString("AAAAAaaaaAAAA"));  
ai0x.setProperty(PropertyIdentifier.units, EngineeringUnits.centimeters);

How do I get them on the DiscoveryTest?

My next question is: how do I get the object property/propertyArray/whathever contains my values?

This is the code from DiscoveryTest:


        for (RemoteDevice d : localDevice.getRemoteDevices()) {
            localDevice.getExtendedDeviceInformation(d);
            List<ObjectIdentifier> oids = ((SequenceOf<ObjectIdentifier>) localDevice.sendReadPropertyAllowNull(d, d
                    .getObjectIdentifier(), PropertyIdentifier.objectList)).getValues();

            PropertyReferences refs = new PropertyReferences();
            for (ObjectIdentifier oid : oids)
                addPropertyReferences(refs, oid);

            PropertyValues pvs = localDevice.readProperties(d, refs);
            // pvs.
            Iterator<ObjectPropertyReference> i=pvs.iterator();
            while (i.hasNext()){
            System.out.println(i.next());
            }
            System.out.println(d);
        }

It is not the property value. It is the propertyArrayIndex that is null. A reference does not have a propertyArray.
