Worked on the nrfconnect/sdk-zephyr repository to improve reliability in embedded network systems by addressing a bug in the SiWx917 Wi-Fi driver. Focused on driver development using C, the work involved correcting multicast filtering to ensure proper handling of IGMP leave events. This was achieved by registering a Zephyr multicast monitor callback, which dynamically updated multicast MAC filters in firmware through sl_wifi_configure_multicast_filter. The fix eliminated unnecessary multicast data reception after group departures, reducing network traffic and enhancing stability for devices in multicast environments. The contribution emphasized code clarity and traceability, with a focus on correctness and maintainability in embedded network programming.

Dec 1, 2025December 2025 focused on reliability improvements in the nrfconnect/sdk-zephyr Wi-Fi driver. Delivered a targeted bug fix for the SiWx917 driver to correctly handle IGMP leave events by adjusting multicast filtering in firmware. Implemented real-time multicast filter management by registering a Zephyr multicast monitor callback (net_if_mcast_mon_register) that invokes sl_wifi_configure_multicast_filter() to add or remove multicast MAC filters as groups are joined or left. This fix prevents multicast data from continuing to arrive after IGMP leave events, improving network stability for devices participating in multicast groups. No new user-facing features were introduced this month; the primary value came from stability, correctness, and reduced network traffic.
