PROFILE
Chang An
Worked on enhancing Bluetooth audio interoperability and reliability within the zephyrproject-rtos/zephyr-testing repository, focusing on Google Pixel device compatibility. Delivered targeted updates to BAP unicast audio and broadcast source samples, addressing codec channel setup errors and improving discoverability through configurable broadcast names. Implemented robust fixes by adjusting ATT prepare counts and validating advertising constraints, ensuring smoother audio streaming and device discovery. Further improvements included expanding audio configuration metadata and refining synchronization handling in the cap_acceptor sample, which increased cross-device reliability. Utilized C for embedded systems development, applying expertise in audio processing, Bluetooth protocols, and device driver integration throughout the work.

Aug 1, 2025In August 2025, delivered two critical updates in zephyr-testing focused on Pixel device compatibility and discoverability. Pixel-specific fixes for BAP unicast audio improve streaming reliability by correcting sink/source location counts and increasing the ATT prepare count, and a Pixel-aware configuration for the bap_broadcast_source sample enhances discoverability by validating length constraints and ensuring proper advertising.
