How to add COV (Change of Value) functionality

  • Hi,


    I am creating BACnet slave device using BACnet4J.
    For doing so I used Slave Device Test Program.
    It is currently supporting Read Property Request.

    Now, I want to add COV (Change Of Value) to be functional.
    Is there need of any additional code or just need to enable this functionality
    and How should I do it?
