Worked on stabilizing the Sensor Shell within the telink-semi/zephyr repository, focusing on embedded systems and device driver development using C. Addressed a critical stability issue by implementing missing channel and attribute definitions, ensuring that newly added sensor channels and attributes are properly recognized by the system. This technical approach prevented crashes that previously occurred when debug logging was enabled, thereby improving the reliability of the sensor subsystem during both development and field use. The work demonstrated effective debugging and patch delivery in a Zephyr-based environment, contributing to safer and more robust sensor operations without introducing new features during the period.
