BACnet Secure Connect Example CPP

A basic BACnet Secure Connect (BACnetCS) server example written in C++ using the CAS BACnet Stack.

If you are looking for a free open source java implmeation of BACnet/SC I suggest looking at the BACnet/SC Reference Stack

User Input

When the application is running and has successfully connected to a BACnet SC Hub users can use the following commands:

• 'w' - Sends a Who-Is message. All results can be viewed in the output log.
• 'q' - Exits the application.

More functionality will be added in the future.

Releases

Build versions of this example can be downloaded from the releases page: https://github.com/chipkin/BACnetSecureConnectExampleCPP/releases

Testing

A WebSockets test server node application is included in this repo.

• \NodeTestWSServer\ for unsecure websockets,
• \NodeTestWSSecureServer\ for websockets with SSL

Install and run:

npm install
npm run run

NOTE:
To run the secure connection example, you have to generate your own certiifcate and private key pair, named cert.pem and key.pem and placed in \BACnetSecureConnectExampleCPP\ and \NodeTestWSSecureServer\.
You must also update \NodeTestWSSecureServer\app.js:5-7 accordingly.

If testing with the BACnetSC Reference Stack, copy the cert and key for the example you are using to the main project directory

Build

A Visual studio 2022 project is included with this project. This project is also auto built using Gitlab CI on every commit.

The CAS BACnet Stack submodule is required for compilation.
