Could not run BACShark in parallel about bacnet HOT 8 CLOSED

Hi @dibrony, you are correct, by default the library will use any local interface to send the requests (at least for broadcasts but for unicast it will choose the right interface, so it shouldn't mix it). But if you specify the localEndpointIp for the transport, then you should limit it to that particular interface.

As to why it's blocking BACShark, it's because you are trying to use two apps and have them listen on the same port (47808). This is possible using Yabe and custom app using this library, becuase the original author has created a special mode where there is a shared connection for multiple applications to use, so you can also run multiple instances of Yabe when you don't change the Yabe settings to use exclusive port. If you just want to check if the communication is running fine, just use Wireshark and filter the traffic to bacnet.

BTW, what is BACShark? I couldn't find it with quick Google search. Is that some BACnet client I could download and test?

Hi,

Thank you @gralin for the above info, I have also checked your answer on my other issue (#66). I will try them within few hours.
However, I noticed something yesterday while trying my code: the data I sent through BACnet is reained locally, the other guy is not able to see them on his PC via the server (as he can see other machines parameters...). Do you think setting the useExclusivePort to true will solve this problem ?

As for the BACShark, I can share it with you for testing, it is around 4MB, how can I send it to you ?

Hi again,

Also there is something called network number (if i am not mistaken), we need it to be 100. How can I set it please ?
Just found your email, I will send you the program now.

The API of this library is a bit tricky, that's something I didn't change and it's inherited from the original implementation inside YABE. So you declare the network value in the BacnetAddress which you later provide as agument to read/write values from remote objects.

var address = new BacnetAddress(BacnetAddressTypes.IP, "192.168.1.100", network: 100);

Yes, could be, the other device might ignore packets coming from different port than 0xBAC0. Best way to verify is to run Wireshark on the server, filter by bacnet and see if the UDP packets are being received. There might also be some firewall issues along the way.

As for the BACShark, I can share it with you for testing

Thanks, I will take a look at it later.

Hi,

Thank you for your support, it seems to be working now.

However it is not sending the Alarm notification to the monitor, i think it is related to the receipient list property (Bacnet type: Destination). I am not able to add this property.

Can you help in this ? any example please ?

Regards

from bacnet.

Hi @dibrony can you please clarify, do you want to receive alarm notification in your code or do you want to send it?

from bacnet.

Hi @gralin,

I want to send an alarm notification to the server (according to an input I have).
Device instance=200 (server)

Note that my code is based on you example Bacnet.Room.Simulator

Thank you

Ok and you are interested in
