Format to set the Recipient Address of NotificationClass Object.

[BMPC2023]

Hi @JoelBender Sir, Is their any proper format for setting the IPv4 address in the Recipient Address of notificationClass Object.

And I have tried the following structure sir but I am getting the Error

NotificationClassObject( objectIdentifier="notification-class,1", objectName="nc1", description="test notification class", notificationClass=1, priority=[9, 9, 9], # toOffNormal, toFault, toNormal priority ackRequired=[0, 0, 0], # toOffNormal, toFault, toNormal recipientList=[ Destination( validDays=[1, 1, 1, 1, 1, 1, 1], fromTime=(0, 0, 0, 0), toTime=(23, 59, 59, 99),

recipient=Recipient(address=DeviceAddress(networkNumber=0,macAddress=Address("192.0.168.189").addrAddr)),

recipient=Recipient(device="device,990",address=DeviceAddress(0,b"\x48\xE7\xDA\x95\x94\x63")),

recipient=Recipient(device="device,990",address=DeviceAddress(networkNumber=255, macAddress=IPv4Address("192.0.168.189").addrAddr)), processIdentifier=0, issueConfirmedNotifications=True, transitions=[1, 1, 1], # toOffNormal, toFault, toNormal ) ], )

I have tried 3 formats in which all gave error

Error:

The Recipient is a choice between the device referencing an object identifier of a device object (in which case the application will need to resolve it) or an address, commonly referred to as a form of "static binding". You have provided both.

But beside that, there is a different problem with converting a DeviceAddress to a version that is context encoded. The fix for it is stacked up behind a separate problem, so in the mean time please use the form Recipient(address="255:192.0.168.189") and that will set both the networkNumber and macAddress correctly.
