I’m integrating a lightweight, cross-brand vehicle-diagnostics (like scanmatik diagnostic software) layer into an existing Windows application and need a DLL (or small EXE with a callable API) that is fully compliant with both J2534 PassThru and RP1210 PassThru. The core function set is simple but must be rock-solid and broad in ECU coverage: • Read and return VIN • Read Hardware Number • Read Software Number • Read Software Upgrade Number • Read MCU identifier - Read/Clear DTCs - Reflahing (if possible) You may build the library in C, C++ or C#. As long as the finished binary runs on Windows and conforms to the two PassThru specs, I’m happy. Transport-level details are flexible—I’m not locked to CAN, K-Line, Ethernet or any other single medium, so choose whichever approach best meets the compliance requirements and offers the widest ECU reach. Future expansion is likely, so please architect the code for easy addition of further diagnostic services; we can scope those in a follow-up milestone once the essentials above are stable. Deliverables • Compiled 32-/64-bit DLL (or EXE + header) for Windows • Complete, well-commented source code • Brief API reference and simple sample project (console or WinForms) demonstrating each required call If this fits your expertise in automotive communication stacks and you can prove compliance with J2534/RP1210, I’d like to see a short outline of your approach and estimated turnaround. (Obs.: we have a VCI J2534/RP1210 and ECU modules to test)

Hello, I yave experience with the J2534 protocol. I have never used the RP1210 diagnostic interface, but I know that therenare C# libraries which can be used. I can create a C# application, which will use either a J2534 or a RP1210 diagnostic interface and will read the VIN from an ECU. The VIN reading is a standard command, however the other functions from your list aren't, so I would need to have some communication logs in order to see how to read these parameters I am looking forward to your response. Kind regards, Drago

✋ Hi, there. I can develop a fully compliant J2534/RP1210 diagnostic DLL for your Windows application that covers all the core ECU functions you need. ✔️ I have extensive experience in automotive diagnostic software and have built similar projects where I developed DLLs and EXEs that handled VIN reading, hardware/software numbers, DTC reading and clearing, and reflashing for multiple ECU types. I have worked with J2534 and RP1210 standards directly, ensuring full PassThru compliance and broad protocol support across CAN, K-Line, and Ethernet. ✔️ I will design the library in C++ for performance and maintainability. Each API function will be clear and tested: reading VIN, hardware number, software number, software upgrade number, MCU identifier, reading and clearing DTCs, and reflashing. The transport layer will be modular to allow easy integration of future protocols. I will structure the code for future expansion so new diagnostic services can be added without major changes. ✔️ Deliverables include a compiled 32-/64-bit DLL (or EXE + header), complete commented source code, a short API reference, and a sample project (console or WinForms) demonstrating all required calls. I will also run tests with your provided VCI and ECU modules to ensure compliance and reliability. Let's chat to review your specific requirements and finalize a timeline for delivery. Best regards, Mykhaylo
