Used a Bluetooth OBD-II adapter, I did, to communicate with the vehicle’s ECU. Data from the CAN bus, retrieved using the adapter, I did. Parsed the data and displayed real-time vehicle information, such as engine status and fault codes, I did. Ensured accurate and secure data transmission, I did, using proper error handling and validation techniques. Technologies involved, Bluetooth API and custom protocol parsers, they were.
