Re: Bacnet IP throwing errors

Hi,
it seems as if a have the exaxt same problem. In the beginning I alswaxys get the
following "not being able to enter a client into the un-acked messages list" error.


Could you maybe provide the jar-file to me as well?

Thanks,

Hi tstorek,

What version of Mango and Bacnet are you using? I would encourage you to consider upgrading to Mango 3, as Matthew (BACnet4J's author) updated and revised it recently.

[tstorek]

I'm only using the bacnet4J bundle itself in a different environment. But no sure from when the bundle is. Maybe an update will help already. Is the bugfix that your suggested earlier already implemented int he bundle?

[phildunlap]

The bugfix was certainly recommended to Matthew. I believe he did accept it.

Here's the github repo: https://github.com/infiniteautomation/BACnet4J

Here's the releases page: https://github.com/infiniteautomation/BACnet4J/releases

If you're interested in what that suggested bugfix was, it was returning in DefaultTransport:send if the link service was null instead of returning slightly later, after entering an ack expectation for a message that couldn't be sent.

Thank you for your help. I couldn' spot it in the release notes. I will try to update my version. It might help:)

Sorry I misspoke, it's in DefaultTransport:Outgoing:send

From...

if (targetNetworkNumber != Address.LOCAL_NETWORK && targetNetworkNumber != Address.ALL_NETWORKS
                    && targetNetworkNumber != network.getLocalNetworkNumber()) {
                // Going to a specific remote network. Check if we know the router for it.
                linkService = networkRouters.get(targetNetworkNumber);
                if (linkService == null)
                    handleException(new BACnetException(
                            "Unable to find router to network " + address.getNetworkNumber().intValue()));
            }

to...

if (targetNetworkNumber != Address.LOCAL_NETWORK && targetNetworkNumber != Address.ALL_NETWORKS
                    && targetNetworkNumber != network.getLocalNetworkNumber()) {
                // Going to a specific remote network. Check if we know the router for it.
                linkService = networkRouters.get(targetNetworkNumber);
                if (linkService == null) {
                    handleException(new BACnetException(
                            "Unable to find router to network " + address.getNetworkNumber().intValue()));
