      Hi Matthew,

      I am trying to set a COV subscription to a (virtual) device's present value using a SubscribeCOVPropertyRequest. By "virtual device" I mean I am creating the device(s) via bacnet4j. I receive the following:

      
      Unsupported confirmed request: invokeId=61, from=Address(networkNumber=0, macAddress=[c0,a8,19,2b,ba,c0]), request=com.serotonin.bacnet4j.service.confirmed.SubscribeCOVPropertyRequest
      ...
      Caused by: com.serotonin.bacnet4j.exception.ErrorAPDUException: ErrorAPDU(choice=127, errorClass=Services, errorCode=Service request denied)
      	at com.serotonin.bacnet4j.LocalDevice.send(LocalDevice.java:424)
      	at com.serotonin.bacnet4j.LocalDevice.send(LocalDevice.java:403)
      	at com.serotonin.bacnet4j.LocalDevice.send(LocalDevice.java:396)
      
      

      Could you please comment on the level of support for SubscribeCOVPropertyRequest on real devices?

        On the requestor side it is supported. On the recipient side, SubscribeCOV is supported, but not SubscribeCOVProperty.

        Best regards,
        Matthew

            I implemented my own SlaveDevice and it is supporting SubscribeCOV but not SubscribeCOVProperty. But I would like to subscribe just one property, not all. How Can I achieve that my slavedevice supports this?
