Worked on enhancing the reliability of the NCP data path in the espressif/esp-zigbee-sdk by addressing a critical SLIP framing issue. Introduced a UART pattern detector in C to segment incoming data streams into individual SLIP frames, which improved data integrity and processing efficiency, particularly under high host data rates. This solution reduced the occurrence of checksum-rejected frames and stabilized communication within embedded systems using UART. Demonstrated strong protocol handling and low-level debugging skills while integrating the fix through the standard git pull request workflow. The work focused on bug resolution, contributing to the overall robustness of the Zigbee SDK.
