[HELP] BACnet Connector Doesn't Detect BACnet Device

[AhmadMagdi]

Describe the issue I have The Thingsboard IoT Gateway up on a virtual machine, and I'm trying to get the BACnet connector to work. I have, on the same local network, another virtual machine running a BACnet device using BACnet Stack, which responds to WhoIs requests by sending an IAm request (I can verify this using BACnet Stack WhoIs).

The connector logs show the gateway sending WhoIs requests, but never receiving the IAm requests sent in response.

Hi @AhmadMagdi ,

Please try to use 0.0.0.0:47808 as an address in general section.

[AhmadMagdi]

Thanks @zbeacon

This worked for me.

Is there a specific reason it should be this way, perhaps some resource I should check out?

[WeiTangLau]

This worked for me as well.

My guess would be as 0.0.0.0 is used to indicate all ipv4 addresses. As such, gateway will accepts and listens to all responses in the network.

However, adopting this method, I am still unable to read BACnet MSTP devices. Do you happened to have a BACnet MSTP device in your network?

[AhmadMagdi]

Hi @WeiTangLau

Thanks for the response!

Unfortunately, I do not have a BACnet MSTP device in your network.
