Developed and delivered Public Broadcast Announcement (PBP) feature support within the Bluetooth tester framework for the telink-semi/zephyr repository, focusing on automated validation of Bluetooth PBP commands. The work involved implementing new configurations, source files, and handlers in C to exercise the PBP flow, integrating with the AutoPTS testing framework to expand test coverage. By enabling automated PBP testing, the contribution improved the readiness of the Bluetooth stack for new features and reduced reliance on manual validation. The project leveraged expertise in Bluetooth protocols, embedded systems, and testing, resulting in measurable business value through faster and more reliable feature verification.
