February 2026 highlights Zephyr GNSS u-blox integration: delivered a unified GNSS u-blox interface for M8 and F9P drivers, consolidating driver logic into a single, user-facing path with a common configuration surface. Introduced the GNSS_U_BLOX switch and shared configuration for satellites count and reset-on-init, enabling consistent behavior across receiver variants. Implemented robust baudrate management with UBX CFG-VALSET support and version polling to avoid unnecessary reconfiguration, alongside a streamlined NMEA output control and a new message retrieval API. Modernized the codebase with a dedicated u_blox folder and YAML bindings, setting the foundation for easier maintenance and future expansion.

August 2025 monthly summary for zephyrproject-rtos/zephyr-testing: Delivered targeted bug fixes and configuration cleanups to improve reliability and maintainability. Key changes include removing AES hardware support from STM32U575 in the device tree to align with hardware capabilities and ST documentation, and correcting GNSS driver boolean translation for is_tracked and is_corrected to ensure accurate data interpretation. Impact: reduces misconfig risk, improves GNSS data integrity, and simplifies future maintenance. Technologies demonstrated include device tree management, embedded driver development, and code hygiene.
