<![CDATA[Support for SubscribeCOVPropertyRequests?]]>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 recipient side, SubscribeCOV is supported, but not SubscribeCOVProperty.

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?

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