During January 2026, Rasmus Sølvmose Larsen enhanced Bluetooth audio streaming in the Zephyr4Microchip/zephyr repository by developing a feature that enables PACS location support and stream operations for both Sink and Source directions. He focused on robust initialization and management of audio contexts, ensuring proper PACS registration and capability exposure for HA_LEFT, HA_RIGHT, and Banded profiles. His work included automatic startup of sink ASEs when enabled by the client and improved the streaming lifecycle for NRF5340 devices. Utilizing C and embedded systems expertise, Rasmus delivered a well-integrated solution that strengthened Bluetooth streaming reliability and hardware configurability without introducing regressions.
