Unable to connect to the example ObjectBrowseSample using the YABE tool

[SamShekhovtsov]

hi. let me explain my concern. I'm learning the Bacnet protocol so I've used this example code and tried to connect to the Bacnet server from the YABE tool with GUI. However, I can't get any information other than the deviceId. There are no error details, no desription at all. The information on the internet is very limited, I couldn't find anything meaningful regarding the .Net C# and Bacnet.

Here is the log that I've got:

Sending WhoIs ... 
UnconfirmedServiceRequest
Sending Iam ... 
UnconfirmedServiceRequest
Transport disposed (at EndReceive): 192.168.73.134

Didn't get response from 'Object List'

The problems are:

the WhoIs doesn't work
the Iam doesn't work
the ObjectList doesn't work

I can't debug the code when the request is sent from the YABE tool.

Could you please help me to understand how this should work? What I'm doing wrong?
