PROFILE
Devika Raju
Devika Raju focused on enhancing network reliability in the nrfconnect/sdk-zephyr repository by addressing a multicast filtering issue in the SiWx917 Wi-Fi driver. She implemented a targeted bug fix in C, leveraging her expertise in driver development and embedded systems to ensure that multicast MAC addresses are properly managed when IGMP leave events occur. By registering a Zephyr multicast monitor callback, Devika enabled dynamic updates to multicast filters through the firmware, preventing unnecessary multicast data after group departures. Her work improved network stability and reduced traffic, with clear, well-documented code that demonstrates a deep understanding of network programming and embedded driver integration.

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.
