September 2025: Delivered two critical updates in nxp-upstream/zephyr to enhance mixed-mode AP support and security. Key deliverables: 1) Auto-select strongest PSK security mode (WPA/WPA2/WPA3) in hostap for mixed-mode deployments, updating key management and protocol settings to automatically choose the most secure mode based on AP capabilities (commit 3e92c3f5aba325da0ed239cd662f79238d6b12fa). 2) WPA2 group cipher compatibility fix for mixed-mode AP connections by defaulting the WPA2 group cipher to include both TKIP and CCMP, preventing connection failures with external APs (commit f72f7a27e923980e864dfa926c50545f7ecc9864).

August 2025 focused on improving 11V roaming reliability in the Zephyr upstream (nxp-upstream/zephyr). Delivered a targeted fix in the hostap module that flushes unused BSS entries before 11V roaming, preventing reliance on outdated scan data and enhancing roaming stability. This work reduces roaming-related disconnects and improves user experience for devices relying on 11V roaming.

In July 2025, delivered core Wi‑Fi security and configuration improvements across two Zephyr-based repositories, strengthening connection reliability, security posture, and operational flexibility. Key work includes OKC support in hostap, cipher suite fixes for WPA2/WPA3/SAE, and a new wifi config command for STA mode. These changes reduce connection failures, improve performance, and streamline Wi‑Fi management for deployments.

2025-06 Monthly Summary: Focused on hardware integration, driver enhancements, and memory-performance optimizations across AmbiqMicro/ambiqzephyr and nxp-upstream/hal_nxp. Delivered NXP M.2 2LL Wi-Fi/Bluetooth integration with triple-UART plumbing, added SAP inactivity duration fetch in the Wi-Fi driver, enabled monitor mode and default 11AX density for IW610/RW610, and optimized wifi_nxp memory layout to ITCM/DTCM with dead-code removal for performance gains. These contributions expand hardware compatibility, improve diagnostics, and boost runtime efficiency.

May 2025 monthly summary focusing on hardware support enablement and firmware/data integration for the IW610 platform across AmbiqMicro's Zephyr-based stack. Delivered end-to-end IW610 readiness by integrating hardware support in AmbiqZephyr and firmware/blob data in hal_nxp, along with regional TX power data and manifest/driver updates.
