Re: [Bacrabbit-developers] BBMD / broadcast

[Self <pe...@se...>]

Hi Rogerio,

Hope you are finding the Rabbit port of the BACnet stack usefull.

I'd have to have a think about this one but perhaps you would need to special case the 
broadcast processing and pass it to the local BACnet stack in addition to broadcasting it to 
the local network. There would need to be some special handling even if you could receive 
your own broadcasts otherwise the BBMD would continuously recirculate the broadcasts...

I haven't had to implemented BBMD support in our products so far and so haven't looked at it 
in detail.

It might be worth trying the same thing with the latest code from the standard C version of the 
stack and see how it handles this. I havent kept things as up to date between the two stacks 
as I would like to due to work pressure and the BBMD support may have been changed.

You could also try asking the question on the main Cornell BACnet list and the developer list 
for the C version of the stack.

Regards,
Peter

[Bacrabbit-developers] BBMD / broadcast

[Rogerio Z. <ro...@za...>]

Hello,

 

We are doing some tests with BBMD on the Rabbit 6700 series.

When the Rabbit receives a WHO-IS Original-Unicast message, this message is
retransmitted as Original-Broadcast.

But when the Rabbit retransmits it, the message is not being captured by it
and the I-AM message is not sent.

 

When the broadcast message is sent by another BACnet device on the network,
the Rabbit captures and handles the message correctly.

What should we do to capture correctly a Broadcast message, sent by the
Rabbit itself?

 

Regards,

Rogerio
