Installation

1. Place CASBACnetStack_x64_Debug.dll into REPO_DIR/bin/

2. (optional) Set network settings at program.js:30, if left empty the program will get your system's active network configuration

   // Settings
   const SETTING_BACNET_PORT = 47808;  // Default BACnet IP UDP Port.
   const SETTING_DEFAULT_GATEWAY = []; // Set Default Gateway to use for BACnet (i.e. [192, 168, 1, 3])
   const SETTING_IP_ADDRESS = [];      // Set IP Address to use for BACnet (i.e. [192, 168, 1, 3])
   const SETTING_SUBNET_MASK = [];     // Set Subnet Mask to use for BACnet (i.e. [255, 255, 255, 0])

3. Run the following

sudo apt install build-essential npm install node program.js
