In April 2026, the nrfconnect/sdk-nrf project focused on stabilizing cold-boot behavior for devices without the SECURE bit by correcting the RRAMC region reset value. The fix replaced a hardcoded default (0x0000000f) with the HAL-provided NRF_RRAMC_REGION_CONFIG_PERM_MASK to compute the correct reset state across SoCs, ensuring fprotect_area() no longer reports -ENOSPC during cold boot on affected devices (notably nRF54LS05). This change minimizes boot-time failures, improves reliability of secure memory protection, and aligns behavior across heterogeneous Nordic SoCs.

March 2026 monthly summary for nrfconnect/sdk-nrf: Focused on delivering new Precision Finding (PF) capabilities for Bluetooth Fast Pair (PF) via the Find Hub Network (FHN), along with Device Tree (DTS) based partitioning migration and related build/config cleanups. Delivered 14 commits across API, ranging applications, samples, and docs. Key outcomes include enabling precise distance measurement for PF accessories using BLE Channel Sounding, introducing a PF API header and implementation, build-time control (CONFIG_BT_FAST_PAIR_FHN_PF), and a ranging module in the locator_tag sample. DTS migration deprecates Partition Manager, preserves flash layout for compatibility, and aligns with Zephyr guidelines (CONFIG_USE_DT_CODE_PARTITION). Added comprehensive documentation updates (integration guide, core docs, release notes) and targeted maintenance improvements (rename alignments, Kconfig placement) to improve maintainability and developer experience. Business impact includes enhanced user value through accurate PF distance measurement, reduced maintenance overhead, and improved build reliability across supported boards.

February 2026 month-in-review: Modernized core Fast Pair architecture and updated NVM partitioning, migrated to Device Tree across samples and tests, deprecating Partition Manager and removing non-secure board target support where applicable. Also renamed Find My Device Network (FMDN) to Find Hub Network (FHN) with a new canonical header and backward-compatible wrappers, updating API hooks, documentation, and Kconfig options. Strengthened build and test infrastructure with simplified provisioning address calculation, fixed a build warning in the Ranging Service, and added a build-only regression test to verify legacy FMDN/PM compatibility across multiple SoCs. These changes deliver clearer APIs, improved modularity, and a stronger foundation for future enhancements, driving maintainability, security posture, and faster iteration for customers.
