I mean that the notification doesn't work, but no exception is made.

when i send this subscription, i received just one time the notification.

Hi,

I have always the same problem with the subscriptionCOV service. I want to make it without cancellation. So from the spec we have :

13.14.1.5 Lifetime

This parameter, of type Unsigned, shall convey the desired lifetime of the subscription in seconds. A value of zero shall
indicate an indefinite lifetime, without automatic cancellation. A non-zero value shall indicate the number of seconds that
may elapse before the subscription shall be automatically cancelled. If both the 'Issue Confirmed Notifications' and 'Lifetime'
parameters are absent, then this shall indicate a cancellation request. If the 'Lifetime' parameter is present then the 'Issue
Confirmed Notifications' parameter shall be present.
So i put this

SubscribeCOVRequest service = new SubscribeCOVRequest(
					new UnsignedInteger(1), objectIdentifier,
					new Boolean(true), new UnsignedInteger(0));
try {
        localDevice.send(remoteDevice, service);
	log.info("subsciption of " + objectIdentifier.getObjectType()
						+ "-" + objectIdentifier.getInstanceNumber() + " done");
} catch (BACnetException e) {
	log.error("unable to send <SubscribeCOVRequest> for the Object "
		+ objectIdentifier.getObjectType()+  "-"+objectIdentifier.getInstanceNumber()+ "\t"+ e.getMessage());
}

I tested lifetime = null, but it doesn't work

thanks for help

Hi,

Thanks for your help, i didn't do that

It works know

Hi,

I have a problem with a new ObjectType that i added, it's CREDENTIAL_INPUT

when i execute
for each propertyReference i do

Encodable encodable = props.getNoErrorCheck(oid, pr);

pr is **PropertyReference **and props is PropertyValues and oid is my ObjectIdentifier

the result is

type.toString()=Credential Input
+pr.toString()=Object name--AmbiguousValue
+encodable.toString()=Ambiguous([75,e,0,4f,54,45,53,20,52,45,41,44,45,52,20,31])
+pr.toString()=Object identifier--AmbiguousValue
+objectIdentifier=Ambiguous([c4,9,40,40,0])
+pr.toString()=Object type--AmbiguousValue
+pr.toString()=Description--AmbiguousValue
+pr.toString()=Present value--AmbiguousValue
+pr.toString()=Status flags--AmbiguousValue
+pr.toString()=Reliability--AmbiguousValue
+pr.toString()=Out of service--AmbiguousValue
+pr.toString()=Update time--AmbiguousValue
updateTime=Ambiguous([])
+pr.toString()=Profile name--AmbiguousValue
instanceNumber=16384

Do you have an Idea ?

thanks for help

Hi,

I have a question about SubscribeCOVRequest; it is possible to make the subscription COV for all time and not for a specific lifetime ?

thanks for help

With VTS, when i sent UnconfirmedTextMessage, i specified a numeric class witch doesn't exists, so my application throws exception

thank you for your help

Hi,

I found the solution of my problem. On VTS I configured the network as remote network but i test in local network. So i changed it and now i receive informations from my application

Thank you for your help.

Just an other question, i have this exception when i send UnconfirmedTextMessage via VTS :

com.serotonin.bacnet4j.exception.BACnetException: Error while creating APDU:

do you know why ?

thanks

Hi,

I am new in Bacnet and Bacnet4J. I am developping an slave bacnet application. this application has to discover a list of bacnet objects/devices and after to manage its. I am using VTS (Virtual Tset Shell) to test my application.
I have some questions, so :

1- i create a localDevice

LocalDevice localDevice = new LocalDevice(1, "10.193.224.255", "10.193.224.239");

10.193.224.255 : address broadcast
and after i initialise it

try {
         	localDevice.initialize();
         }catch(IOException e) {
         	System.out.println("IO Error!");
         	e.printStackTrace();
         	return;
         }

finally i send a broadcast request

localDevice.sendBroadcast(0xBAC0, new WhoIsRequest(null, null));

but the list of object is empty and VTS doesn't receive any thing, i don't know why because with VTS i create devices and objects that have "10.193.224.177" address IP. So i don't know how i can do this

2- what is the different between remoteDevice and localDevice ?

3- second test : with VTS i send WhoIsRequest

after i create a bacnet object in my application

LocalDevice localDevice = new LocalDevice(1, "10.193.224.255", "10.193.224.239");         
         BACnetObject bacnetObj = new BACnetObject(localDevice, new ObjectIdentifier(ObjectType.analogInput, 10));
         bacnetObj.setProperty(PropertyIdentifier.objectName, new CharacterString("TemperatureSensorOneRF"));
         bacnetObj.setProperty(PropertyIdentifier.description, new CharacterString("Controller of TemperatureSensor"));

after i send :

 localDevice.sendBroadcast(0xBAC0, new IAmRequest(new ObjectIdentifier(ObjectType.analogInput, 10), new UnsignedInteger(1024), Segmentation.noSegmentation, new UnsignedInteger(236)));

But VTS doesn't receive any thing

I am new in bacnet devloppment, i develop a bacnet driver Bacnet/IP.
and i search for an example of creation connection Bacnet/IP and test creation BacnetObject
I use the VTS stack to test
thanks
