I use the same adapter and I had similar problems (mango 1.4.2?) on linux - after recompiling mango the problem vanished mysterious - I don't know why...

Currently I tested it with mango 1.6.4 on winXP - it runs out of the box.

So my gues is it cant find the COM-Port.
The COM-Port driver is a FTDI 2.4.16.0 (in the Device-manager - (System->Hardware->COM-Ports or similar).

Does the OneWireViewer.exe (it is a Javaprogram with an exe-wrapper) show the adapter an the devices?

Arne

Which OS and adapter do you use?

Arne

Hi I am need to scan a list of devices (MBus).
This can take some time (i.e. modem dialin) - is BACNetDiscovery the answer for an template?

Arne

Ok,

here we go:

the classname was a typo, thank you.

You (or probably me) can improve it to pass a broadcastaddress and timeout via main().

Arne

Thank you, iI got it from CVS.

so here is my next "streamlined" ex DiscoveryTest example

It sends a WhoIs Request, waits for the first device to answer (in doDiscover()).
And then it requests all available Properties with PropertyIdentifier.all.
Then it prints the properties sorted by ObjectId.

If you find this useful, you may add this to CVS.

If you interested, I would write a read specific property the old DiscoveryTest and a writeProperty test.

Hi,

is it really necessary to set localDevice in the constructor of com.serotonin.bacnet4j.obj.BAcnetObject, doing this in localDevce.add() should be the better way?

Create wrappers for the base Objects (BAchnetObject)
that implement the required and optional properties?
=> AnalogInput
like this:

public class AnalogInputDoubleObject extends BACnetObject {

public AnalogInputDoubleObject(LocalDevice localDevice, ObjectIdentifier id) throws BACnetServiceException {
        super(localDevice, id);
    }

public AnalogInputDoubleObject(LocalDevice localDevice) throws BACnetServiceException {
        this(localDevice, localDevice.getNextInstanceObjectIdentifier(ObjectType.analogInput));
    }

public void setPresentValue(double value) throws BACnetServiceException {
        setProperty(PropertyIdentifier.presentValue, new com.serotonin.bacnet4j.type.primitive.Double(value));
    }

@Required
    public double getPresentValue() throws BACnetServiceException {
        final com.serotonin.bacnet4j.type.primitive.Double value = (com.serotonin.bacnet4j.type.primitive.Double)getProperty(PropertyIdentifier.description);
        return value == null ? null : value.doubleValue();
    }

public void setDescription(String description) throws BACnetServiceException {
        setProperty(PropertyIdentifier.description, new CharacterString(description));
    }

@Option
    @Override
    public String getDescription() {
        return super.getDescription();
    }

public void setUnits(EngineeringUnits units) throws BACnetServiceException {
        setProperty(PropertyIdentifier.units, units);
    }

@Required
    public EngineeringUnits getUnits() throws BACnetServiceException {
        return (EngineeringUnits)getProperty(PropertyIdentifier.units);
    }

public void setDeviceType(String deviceType) throws BACnetServiceException {
        setProperty(PropertyIdentifier.deviceType, new CharacterString(deviceType));
    }

@Option
    public String getDeviceType() throws BACnetServiceException {
        final CharacterString value = (CharacterString)getProperty(PropertyIdentifier.description);
        return value == null ? null : value.getValue();
    }

public void setOutOfService(boolean value) throws BACnetServiceException {
        setProperty(PropertyIdentifier.outOfService, new com.serotonin.bacnet4j.type.primitive.Boolean(value));
    }

@Required
    public boolean getOutOfService() throws BACnetServiceException {
        com.serotonin.bacnet4j.type.primitive.Boolean value = (com.serotonin.bacnet4j.type.primitive.Boolean)getProperty(PropertyIdentifier.outOfService);
        return value == null ? null : value.booleanValue();
    }

And last but noit least create a library of proxies for real Devices that encapsulates the readProperty process and act as "normal" java classes with properties?

Arne

Hi Matthew,

this happends by ObjectType == multiStateOutput and analogOutput

Arne

Sorry,

I thought this belongs also to create a bunch of example that runs out of the box.

Any Idea?

Arne

Hi Matthew,

the offending PropertyId are: 8, 87, 105, which throw a java.lang.reflect.InvocationTargetException.

Should I file a bug against it in the SF bug parade?

Arne

Hi,

trying to read all property values by using this changed code in :

and choose values greater of 12 >> the app will fail.

Any hints?

Arne

So this two classes should work straight out of the box on any machine ;-)
