COV not working with multiStateValue,multiStateOutput,multiStateInput

[danishmhmd]

Hi I was exploring the library for all different COV type but i noticed i am unable to get the COV packets on my listener, however i checked wireshark there seems to be some error of unknown service while subscribing even after that device do sends the notification of which library reply with unknown service. However same is working with a third party online tool i checked called Yabe. PFA screenshot of wire shark with bacnet4j and yabe. Below are the logs which i see when a notification is sent from device: [BACnet4J IP socket listener for device 0] DEBUG com.serotonin.bacnet4j.npdu.Network - Received NPDU from local network.

Have you set COVNotification to TRUE like servicesSupported.setConfirmedCovNotification(true);

[danishmhmd]

Yes as below: remoteDevice.getServicesSupported().setConfirmedCovNotification(true); Here are the console logs of library when i device sends the COV and library reply it with service not supported:-

[BACnet4J IP socket listener for device 0] DEBUG com.serotonin.bacnet4j.npdu.Network - Received NPDU from local network. From=Address [networkNumber=0, macAddress=[a,0,0,66,ba,c0]], local=0 [BACnet4J IP socket listener for device 0] DEBUG com.serotonin.bacnet4j.npdu.Network - Received NPDU from [a,0,0,66,ba,c0]: NPDU [from=Address [networkNumber=0, macAddress=[a,0,0,66,ba,c0]], linkService=null, queue=[0,4,a8,1,9,1,1c,2,0,1e,2c,2c,4,c0,0,5,39,0,4e,9,55,2e,91,0,2f,9,6f,2e,82,4,0,2f,4f]]

After carefully analyzing the wireshark logs sent earlier I noticed the following:

1. 10.0.0.100 - BACnet4J as workstation, 10.0.0.102 - Controller having AI,0 and MSV,5.
2. 10.0.0.100 subscribes COV for both AI,0 and MSV,5 which has been accepted by the controller as well.
3. Subsequently AI,0 sent COV notification which was accepted by BAcnet4J.
4. But when the COV is received from MSV,5 it throws error.
5. So the issue is related to MSV and not with COV.

So please look at the code around MSV and if possible share the code so as to reproduce from my side to see how can I help you.

Sure, Please find the sample code snippet below for communication class and listener :-

        IpNetwork network = builder.build();

                    LocalDevice localDevice;

        localDevice.initialize();

I tried the code, but I receicved Simple Ack for MSV,1 and AI,1. Screenshot of the wireshark is enclosed.

192.168.1.143 - BACnet4J

[danishmhmd]

I guess i found the issue i was using version 5.0.0 and you are testing on 6.0.0-SNAPSHOT. Let me once check this with version and update back

[danishmhmd]

Have checked, it is working fine in 6.0.0-SNAPSHOT had the issue with 5.0.0
