I'm having problem with discovery devices when using method 'getExtendedDeviceInformation'. The application stops and after some time I got a timeout error.
To test the BACnet I use VTS application. The VTS respond 4 times but it looks like the BACnet4j doesn't see the responses.

P.S.
Also the VTS can see 'Iam' message so it's not a communication issue.

    public static void main(String[] args) throws Exception {
         LocalDevice localDevice = new LocalDevice(12, "192.168.254.255");         
        localDevice.getEventHandler().addListener(new Listener());
        localDevice.initialize();

        localDevice.sendBroadcast(47808, new WhoIsRequest());

        // Wait a bit for responses to come in.
        Thread.sleep(1000);
        
        // Get extended information for all remote devices.
        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);
