[fh1ch]

This issue shall collect all ideas for advanced features to be implemented in a future release:

• IP linked invokeID counter (see invokeID being sent higher than 255 #22 (comment))
• Implement writeGroupProperty service

Hi, have you any plans to add support for bacnet over RS485 (mstp)?

Hi @hardillb

Sorry, no plans so far. I don't have a use-case for it and don't know MSTP to well. However, BBMD support is currently in the making and acessing MSTP devices over a router should therefore be possible.

@fh1ch
I am working on MSTP discovery right now. I have the who-is-router-to-network request working. I'm now working on the i-am-router-to-to-network response.
One issue i an having is the i-am-router-to-to-network response is a network layer message which the client.js is set to drop any received network layer messages. What is the reason for dropping these messages?
