How to simulate Node Red running hardware as a BACnet device?

I am just trying to utilize the existing bacnet nodes (node-red-contrib-bacnet) to configure my hardware (ubuntu based) as a BACnet device that can expose some messages as a BACnet objects. So other BACnet browser or application can read messages from my node-red. But I think these nodes only supports read data from other BACnet device and it cannot be configured in a way I want. Kindly pour your suggestions if i can able to do that.
