      You were correct, this was an error in the way my hardware was responding. The new build fixes that issue.

      I am now however having an issue that keeps happening randomly (but this time simply won't fix itself after many attempts). Bacnet4j sends the packet correctly, and the bacnet device responds, but for some reason bacnet4j won't acknowledge the fact that it received an awk packet. There errors are as following:

      Write property:

      
      public static int WriteProperty(InetAddress Address, int port, int instanceID,  int propertyID,int objectID, float data) throws Exception {
             
          	LocalDevice localDevice = new LocalDevice(1234, "192.168.0.255"); //create new local device
              localDevice.initialize(); //initialize the device
              
              byte[] IPRaw = new byte[4]; //allocate mem for IP address
              IPRaw=Address.getAddress(); //Convert InetAddress into bte array
              
              RemoteDevice rd = new RemoteDevice(instanceID, new Address(new UnsignedInteger(port),  //create a new bacnet drvice with proper Instance ID and IP
                     new OctetString(new byte[] {IPRaw[0], IPRaw[1], IPRaw[2], IPRaw[3]})), null);
              
          	   localDevice.addRemoteDevice(rd); //add newly created bacnet device to the localdevice
          	   ObjectIdentifier oid = new ObjectIdentifier(new ObjectType(propertyID),objectID); 
                 rd.setSegmentationSupported(Segmentation.segmentedBoth); //needed to send packet properly
                 rd.setMaxAPDULengthAccepted(1476); //max length
          	   
          	   RemoteObject ro = new RemoteObject(new ObjectIdentifier(new ObjectType(propertyID),objectID)); //create the object based on the right property ID (usually present value), and object ID.
          	   rd.setObject(ro); //add object to remote device
          	   Thread.sleep(1000); //wait for everything to setup properly
          	   localDevice.setPresentValue(rd,oid,new Real(data)); //send data write packet
          	   
          	   return 1;
      }

      The captured packets are here:

      Another bacnet client that I have does not have this issue with the hardware I am using.
      And help would be greatly appreciated ?

      PS. I know that I am writing 3.3 but it is returning 3.0000. Though this should have nothing to do with this issue.

        If the app had actually received the response and for some reason misinterpreted it, you would see an exception like, "No waiting recipient for message: peer=...". Were there other messages, or just the timeouts?

        Best regards,

          Just the timeout. If you look at the packets in wireshark, bacnet4j sends the request 3 times and gets a reply back each time. For some reason it is refusing to read the awk packet. The packet bacnet4j is sending is identical to the one bacbeat sends out. However, bacbeat recognizes the awk packet and displays the value, while bacnet4j does not, so it shouldn't be a hardware problem.

          The code running those 2 methods are here:

          
           	InetAddress deviceIP = InetAddress.getByName("192.168.16.3");
              	WriteProperty(deviceIP,47808,3331779,2,1,(float)3.3);
                  String result = ReadProperty(deviceIP,47808,3331779,2,1);

            Do you know how to add System.out statements to the code and build the jar? It seems as if BACnet4J isn't getting the response at all, since any other possibility should cause an exception to be thrown.

            If so, add the following line in IpMessageControl at line 424:

                        try {
                            socket.receive(p);
                            System.out.println("Received a packet!");  // ADD THIS LINE
                            incomingExecutorService.execute(new IncomingMessageExecutor(p));
                            p.setData(buffer);
                        }
            
            

            If the packet is being received, then we can go down the BACnet4J road. If not, there must be something else preventing its proper routing.

            Best regards,
            Matthew

              Added the line, and complied.

              When running the line, nothing changed (did not display the "packet received message").

              The question is however, why is bacbeat able to receive the packet while bacnet4j is not?

              I have a few computers here, do you think I should try executing on another one?

                running as root vs. usual user?
                windows firewall?
                port in use by other program?

                  • Running as administrator (windows)
                    -I'll shut off windows firewall and test that theory in a bit, though it was working last week with windows firewall on.
                  • Happens directly after a fresh bootup. Before, when my program didn't exit properly I had to restart it to get it working again (thus the port was in use). On a fresh bootup however, I have doubts the bacnet port (47808) would be in use. I will however try to test for this.

                  Thanks for the tips :)

                    I'm also having the same error "Timeout while waiting for response for id 0 " as Randy.

                    I'm getting it with the following code: localDevice.getExtendedDeviceInformation(remoteDevice);

                    I looked at the wireshark and Bacnet4J is sending the readProperty request for property protocol-services-supported 3 times
                    and my device is answering everytime. I can see the data sent back but Bacnet4J can't seem to catch it.

                    What is weird is that my code was working 1 year ago and tried it again this week and I get this.

                    Anyone found the reason for that problem or a workaround?

                    I suspect that something changed in our bacnet network but I don't know what to look for...

                    thanks!

                    Eric
