sending multiple devices.

[YEJI]

Hello, I'm trying to make multiple BACnet devices in my IP, like(192.168.1.101:1234)(192.168.1.101:1235)(192.168.1.101:1236)
I made one local device in instance number 1234, but I figured out that I can't make multiple local devices in just one IP. (If it can, someone tell me how to do it. I get bind error in initializing.)

so, I made some remote device(instance number 1235) to bind to my local device(instance number 1234), but i can't just add present value to my remote device or just find the remote device.

this is my code. I got sample code from "RemoteDeviceTest.java" file. I don't need assert function to check values.

final IpNetwork network = new IpNetworkBuilder()
		.withBroadcast(properties.getProperty("bacnetBroadcasting"), 16).withPort(47808)
		.withLocalBindAddress(properties.getProperty("bacnetBroadcastingIp")).build();
transport = new DefaultTransport(network);
localDevice = new LocalDevice(Integer.parseInt(properties.getProperty("deviceId")), transport);
final RemoteDevice rd = new RemoteDevice(localDevice, 1236);
final ObjectIdentifier ai1 = new ObjectIdentifier(ObjectType.analogInput, 0);
final ObjectIdentifier ai2 = new ObjectIdentifier(ObjectType.analogInput, 1);
final ObjectIdentifier ai3 = new ObjectIdentifier(ObjectType.analogInput, 2);
final ObjectIdentifier ai4 = new ObjectIdentifier(ObjectType.analogInput, 3);
final ObjectIdentifier ai5 = new ObjectIdentifier(ObjectType.analogInput, 4);

ai1.write(new ByteQueue(new byte[] { 0 }), 0);
ai2.write(new ByteQueue(new byte[] { 1 }), 1);
ai3.write(new ByteQueue(new byte[] { 2 }), 2);
ai4.write(new ByteQueue(new byte[] { 3 }), 3);
ai5.write(new ByteQueue(new byte[] { 4 }), 4);

rd.setDeviceProperty(PropertyIdentifier.objectList, UnsignedInteger.ZERO, new UnsignedInteger(5));
rd.setDeviceProperty(PropertyIdentifier.objectList, new UnsignedInteger(3), ai3);
final SequenceOf<ObjectIdentifier> objectList = rd.getDeviceProperty(PropertyIdentifier.objectList);
rd.setDeviceProperty(PropertyIdentifier.objectList, new SequenceOf<>(ai1, ai2, ai3, ai4, ai5));

try {
	localDevice.initialize();
	System.out.println(localDevice.getRemoteDevice(1));
	localDevice.startRemoteDeviceDiscovery((r) -> {
		System.out.println(r.getInstanceNumber());
	});
	localDevice.getRemoteDevice(0).get();
	localDevice.getRemoteDevice(1).get();
	localDevice.sendGlobalBroadcast(new WhoIsRequest());
} catch (Exception e1) {
	LOGGER.info(e1.toString());
	localDevice.terminate();
}
localDevice.getEventHandler().addListener(new Listener());
localDevice.sendGlobalBroadcast(new WhoIsRequest());
LOGGER.info("Initialized");

and I get this console output.

and If I use YABE, I don't get anything from remote device. I just get local device values.

I want to add some multiple devices to my local device, and send some present values from remote devices.
Can anybody teach me about how to get it?

Thank you. :)

I think I got more closer to answer (or more messed up) but still not working.

final IpNetwork network = new IpNetworkBuilder()
		.withBroadcast(properties.getProperty("bacnetBroadcasting"), 16).withPort(47808)
		.withLocalBindAddress(properties.getProperty("bacnetBroadcastingIp")).build();
transport = new DefaultTransport(network);
localDevice = new LocalDevice(Integer.parseInt(properties.getProperty("deviceId")), transport);
final byte[] a=hexStringToByteArray("10264661021061036466103105103103");
final Address macAddress = new Address(a);
final RemoteDevice rd = new RemoteDevice(localDevice, 1236, macAddress);

final ObjectIdentifier ai1 = new ObjectIdentifier(ObjectType.analogInput, 0);
final ObjectIdentifier ai2 = new ObjectIdentifier(ObjectType.analogInput, 1);
final ObjectIdentifier ai3 = new ObjectIdentifier(ObjectType.analogInput, 2);
final ObjectIdentifier ai4 = new ObjectIdentifier(ObjectType.analogInput, 3);
final ObjectIdentifier ai5 = new ObjectIdentifier(ObjectType.analogInput, 4);

ai1.write(new ByteQueue(new byte[] { 0 }), 0);
ai2.write(new ByteQueue(new byte[] { 1 }), 1);
ai3.write(new ByteQueue(new byte[] { 2 }), 2);
ai4.write(new ByteQueue(new byte[] { 3 }), 3);
ai5.write(new ByteQueue(new byte[] { 4 }), 4);

 // Verify
 try {
       	// Set the object to something else.
        localDevice.send(rd, new WritePropertyRequest(new ObjectIdentifier(ObjectType.multiStateValue, 0),
        PropertyIdentifier.presentValue, null, new UnsignedInteger(2), new UnsignedInteger(8))).get();
        localDevice.send(rd, new WritePropertyRequest(new ObjectIdentifier(ObjectType.multiStateValue, 0),
        PropertyIdentifier.presentValue, null, new UnsignedInteger(4), new UnsignedInteger(98))).get();
} catch (BACnetException e2) {
	e2.printStackTrace();
}						
rd.setDeviceProperty(PropertyIdentifier.objectList, UnsignedInteger.ZERO,new UnsignedInteger(5));
rd.setDeviceProperty(PropertyIdentifier.objectList, new UnsignedInteger(3), ai3);
final SequenceOf<ObjectIdentifier> objectList = rd.getDeviceProperty(PropertyIdentifier.objectList);
rd.setDeviceProperty(PropertyIdentifier.objectList, new SequenceOf<>(ai1, ai2, ai3, ai4, ai5));
rd.setObjectProperty(ai1, PropertyIdentifier.presentValue, new Real(1));
rd.getObject(ai1);

try {
	localDevice.initialize();
	System.out.println(localDevice.getRemoteDevice(1));
	localDevice.startRemoteDeviceDiscovery((r) -> {
		System.out.println(r.getInstanceNumber());
	});
	localDevice.getRemoteDevice(0).get();
	localDevice.getRemoteDevice(1).get();
	localDevice.sendGlobalBroadcast(new WhoIsRequest());
} catch (Exception e1) {
	LOGGER.info(e1.toString());
	localDevice.terminate();
}
localDevice.getEventHandler().addListener(new Listener());
localDevice.sendGlobalBroadcast(new WhoIsRequest());
LOGGER.info("Initialized");

Hi YEJI,

I answered in your other thread, https://forum.infiniteautomation.com/topic/3942/no-response-from-remote-device

Adding more information to this thread to get a better chance of response (which you shouldn't attempt to insist upon) is fine, but there's no reason to bump it by adding more threads.
