Creating a Schedule Object in BACnet4j

[joolz]

I am trying to create a schedule object in BACnet4j using the following (simplified for clarity):

import com.serotonin.bacnet4j.LocalDevice;
import com.serotonin.bacnet4j.exception.BACnetServiceException;
import com.serotonin.bacnet4j.npdu.ip.IpNetwork;
import com.serotonin.bacnet4j.obj.BACnetObject;
import com.serotonin.bacnet4j.transport.Transport;
import com.serotonin.bacnet4j.type.enumerated.ObjectType;
import com.serotonin.bacnet4j.type.enumerated.PropertyIdentifier;
import com.serotonin.bacnet4j.type.primitive.Enumerated;
import com.serotonin.bacnet4j.type.primitive.ObjectIdentifier;


public class ScheduleTest
{
	public static void main(String[] args)
	{
		try
		{
			LocalDevice localDevice = new LocalDevice(21, new Transport(new IpNetwork("255.255.255.0")));
			BACnetObject schedule = new BACnetObject(localDevice, new ObjectIdentifier(ObjectType.schedule, 0));

			schedule.setProperty(PropertyIdentifier.scheduleDefault, new Enumerated(0));
		}
		catch (BACnetServiceException e)
		{
			e.printStackTrace();
		}
	}
}
```However, when I run it, I get this:

com.serotonin.bacnet4j.exception.BACnetServiceException: class=Property, code=Invalid data type, message=expected class com.serotonin.bacnet4j.type.AmbiguousValue, received=class com.serotonin.bacnet4j.type.primitive.Enumerated
at com.serotonin.bacnet4j.obj.ObjectProperties.validateValue(ObjectProperties.java:154)
at com.serotonin.bacnet4j.obj.BACnetObject.setProperty(BACnetObject.java:192)
at ScheduleTest.main(ScheduleTest.java:21)

Hello community,

I am also having some troubles with the Bacnet schedule, or there might be something I do not understand.
Can someone provide a brief example of a working Bacnet schedule object, because I did not find any?

Thanks in advance.
Best regards,

Up.

Has no one succeeded to implement this object ?

I have, but BACnet4j doesn't make it straight forward.

First you need to subclass BACnetObject and make a Schedule object class.
In that schedule object class, have a local variable for schedule default property.
In the constructor, set the present value and schedule default properties with this value:
new AmbiguousValue(new ByteQueue(new byte[]{0}))

Then override the get() and set() methods, so that if the schedule default property is being set/retrieved, you get it from your local variable instead of the property map.

Sorry to answer so lately, I finally found back my login and password for this site.

Tank you Joolz, your comment helped me buld a schedule object. I'll try to paste a very basic example when I'll figure out how to put my code into code tag.
