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

I don't know how and where to look to get the informations for the proprietary message. Do I ask
Delta Controls directly?

Eric

Is there a way to configure Wireshark for getting
only information going to/coming from my Java app?

Thanks for the fast reply!

Hi! I'm working on an acquisition application and I am getting some exceptions when running my application.

My code is:
localDevice = new LocalDevice(1234,serverAddress);
localDevice.initialize();
localDevice.sendBroadcast(47808, new WhoIsRequest());
Thread.sleep(5000);
remoteDevices = localDevice.getRemoteDevices();

I'm finding 30 devices but I'm getting multiple BacnetException and IpMessageControl$MessageValidationAssertionException coming from the library. Any Idea about what's causing this?
