Feature Request / Question

How does one specify the id and address of a device such as shown in the attached imaged.

Current Behaviour (Bug Report)

I tried discovery and read examples. There is a scenario that I cannot get either to work for. I use Yabe to discover the device and the attached image is what it shows. It discovers it and shows a device ID but I cannot get Node BACStack to read or discover this device.

Expected Behaviour (Bug Report)

Should at least be able to read its properties if one specifies its address and deviceID.

Steps to reproduce Issue (Bug Report)

The device is routed via a Moxa gateway that acts as a BACNet router. This issue is also happening when a router is involved.

Yes thats exactly one case I never was able to simulate (because also I never found any od the bacnet simulators that support routers) and because of never having such devices it is very hard to find reasons here. We had such a report before but never got more details, so we were never able to look into it.

So I would propose the following:

• enable all debug log modes in the library and gather infos of the router and devcie and such and post full log incl. all details and messages and such here
• If you have a tool or bacnet browser (windows) tool or such (as I assume seeing the screenshot) also try to check if they expose communication logs - the more low level the better :-) post anything here ... do not limit or obfruscate it (sorry) because else we miss crucial infos

Without having such a device this would be the only way to try to check that the lib is currently doing and compare to what it should do.

Alternative is that you jump on that and provide a PR to add correct bevahvior.

I tried a Python library and it does see the nodes when you set an option: globalBroadcast=True. The device it finds has a strange address (not a Bacnet person myself). I am able to read using that address on their library. That address (1000:0xc0a808730001) is rejected by Bacstack.

Does that lib also have a DEBUG log mode? ;-) and ... which python lib you tried?

[m2b]

I used BAC0 based on bacpypes. Will investigate debug mode.
