BACnet4j2 Integration for Device Communication

I'm seeking a skilled developer to implement the latest bacnet4j2 library into my project. The primary requirement is to enable seamless communication with various BACnet devices, including controllers, sensors, and gateways. Key Responsibilities: - Implement the latest bacnet4j2 library for communication with BACnet devices. - Ensure compatibility with communication methods including IP, MSTP, and Ethernet. - Optimize the system for interaction with diverse BACnet devices such as controllers, sensors, and gateways. Ideal Skills: - Proficiency in Java programming language. - In-depth understanding of BACnet protocol and devices. - Experience with the bacnet4j2 library. - Familiarity with communication methods: IP, MSTP, and Ethernet. - Strong problem-solving skills and attention to detail. More Details: Read below: 1. BACnet Device Discovery: User will input this data: instancenunmber- ip address: udp port Example: 500231-10.x.x.x:47808 2. Adhoc Logging Based on Interval: o The system will implement logging of BACnet objects (e.g., temperature, CO2 levels) at specified intervals. o A configurable interval parameter will allow users to set the logging frequency. o Data collected during logging should be stored in a structured format (e.g., CSV, database) and tagged with timestamps for later analysis. 3. Adhoc-Based Point ID Reading: o The system will allow users to query specific point IDs (BACnet object properties) on demand. Example: Device instance - Device ip address - UDP port - Point ID- point type o This feature will enable manual or programmatic requests for reading properties like present values of specific objects (e.g., temperature, humidity). o The system should also include error handling to manage cases where point IDs are unavailable or inaccessible. 4. BACnet COV (Change of Value) Reading and Subscription: o The system will support BACnet COV reading and subscription to efficiently monitor real-time changes in device properties. o Users will be able to subscribe to specific BACnet points, receiving notifications whenever the value of the subscribed object changes. o This will help reduce network traffic compared to polling methods by only sending data when changes occur. o The system will manage COV subscriptions dynamically and support both device-initiated and client-initiated subscriptions. 5. BACnet Auto Discovery: There should be function to auto discover all device in local network o The system must be able to discover BACnet devices available on the local network. o This discovery process should identify all devices, along with their respective Object Identifiers (Device IDs), network addresses, and supported objects. o The discovery mechanism will trigger periodically or on-demand and should handle both known and unknown devices in the network. 6. Readpropertymultiple Not only present value, should have function to read multiple points 7. Subscription: When I subscribe for point, it should also show point faulty or not.
