How to receive the COV messeges in BACnet4j.jar

[AKUHN]

Hallo everyone, I'd like to know, if I have subscribed to receive the COV messeges in a right way. Here is my code:

void getCOV(LocalDevice localDevice)throws Exception {

	System.out.println("COV");
	System.out.println("===============================");
	/*byte RemoteIP[]={(byte)192, (byte)168, (byte)178, (byte)101};
	Address addr = new Address(RemoteIP, 47808);   	 
	RemoteDevice d = new RemoteDevice(1010194, addr, null);*/
	
	InetSocketAddress addr = new InetSocketAddress(getByName("192.168.178.101"), 47808);
	
	com.serotonin.bacnet4j.type.primitive.Boolean B = new com.serotonin.bacnet4j.type.primitive.Boolean(true);
	
	ObjectIdentifier objekt = new ObjectIdentifier(ObjectType.analogOutput,1);   
	SubscribeCOVRequest covReqq = new SubscribeCOVRequest(new UnsignedInteger(0), objekt,B, new UnsignedInteger(0));
	
	localDevice.send(addr, null, 1476, Segmentation.segmentedBoth, covReqq);

I start the code, and if I change the values of present value parameter on the BACnet Device I get the following in the Wire Shark:

36 15.896980000 192.168.178.101 192.168.178.35 BACnet-APDU 84 Confirmed-REQ confirmedCOVNotification[249] device,1010194 analog-output,1 present-value status-flags
37 15.902518000 192.168.178.35 192.168.178.101 BACnet-APDU 51 Simple-ACK confirmedCOVNotification[249]

I come to a conclusion that my BACnet Device sends the messages. Am I right? If it is so then how do I get (return) this messeges from BACnet4j.jar?

Thank You in advance!
