Hey,

Thanks for helping.

Unfortunately it gives the exact same error.

If it is any help:
executing addPropertyReferences(refs, oid) only on the first oid causes no error and returns:

Starting Discovery Test
localDevice initialized
Sleeping...
Awake.
device list size = 1
device 0 processed?
oids = 40
oid instanceNum = 10000, oid.TYPE_ID = 12, type = Device, intVal = 8

here
readProperties:
RemoteDevice(instanceNumber=10000, address=Address(networkNumber=47808, macAddress=[c0,a8,1,2]), network=null)

Executing addPropertyReferences(refs, oid) on the second oid and onwards causes the Reject.

Any other ideas why this might be happening?

Hello,

I am new to both BACNet as well as bacnet4j. I am receiving RejectAPDUException when I try to read the properties of devices and am not sure how to resolve this.
