Worked on the esrlabs/openbsw repository to enhance the reliability of ISO-TP protocol handling within embedded systems using C++. Focused on stabilizing flow control by addressing a bug in the Flow Control Frame’s minimum separation time encoding, ensuring compliance with the ISO-TP standard. The approach involved correcting the encoding logic and introducing regression tests to validate frame timing semantics, which improved interoperability with downstream CAN Protocol components. Maintained precise traceability by delivering a targeted bug fix and an accompanying test suite. The work demonstrated attention to protocol detail and contributed to more robust and standards-compliant embedded communication software.
