Worked on the UWARG/common repository to improve the reliability of drone hardware testing by addressing a key integration issue. Focused on embedded systems and drone development, the work involved modifying the test infrastructure so that the drone test connection used the physical serial port (/dev/ttyAMA0) instead of a TCP connection. This change, implemented in Python, enabled end-to-end hardware testing and reduced discrepancies between the test environment and actual drone hardware. The update enhanced test stability and provided clear traceability through a referenced commit, supporting future audits and hardware integration efforts while ensuring the test suite more accurately reflected real-world conditions.
