January 2026: Key features delivered and reliability improvements in the nRF Connect SDK repository. Focused on Wi‑Fi coexistence improvements and BT initialization reliability, delivering business value through improved security, startup reliability, and maintainability.

November 2025 monthly summary for nrfconnect/sdk-nrf: Key feature delivered: BLE Throughput Enhancement via Data Length Extension (DLE). Implemented by increasing the BLE controller data length to 251 bytes, enabling DLE and improving throughput in both single-core and dual-core builds. This platform-agnostic change is traceable to a single commit and applied to the samples for consistent behavior across configurations.

May 2025 focused on strengthening documentation accuracy for Wi-Fi/Thread coexistence in the nRF Connect SDK. Delivered targeted corrections to the thread_coex sample README and updated the nRF70 coexistence guide to reflect current node configuration, improving developer onboarding and reducing misconfiguration risk.

April 2025 monthly summary for zephyrproject-rtos/nrf_wifi: Implemented configurable SWCTRL1-based Wi-Fi/Bluetooth coexistence control to improve interference management and power efficiency. The work establishes an API surface and wiring for SWCTRL1 coexistence configuration, enabling both input and output configurations depending on system needs. This lays the groundwork for more robust coexistence in multi-radio environments and smoother integration with host stacks.

March 2025 performance summary for nrfconnect/sdk-nrf: Stability and integration focus on Wi-Fi/BLE coexistence with SHIELD. Implemented targeted fixes to prevent PSK-related malloc failures, ensured SHIELD overlays for Wi-Fi coexistence samples are correctly applied, and tuned BLE supervision timeout to reduce LE disconnects. All changes centered on making Wi-Fi/BLE coexistence reliable in real-world usage and improving developer and customer experience.

Month: 2025-01 monthly summary for nrfconnect/sdk-nrf. Key feature delivered: a new Wi-Fi / SR Coexistence Configuration Command (config_pta) added to the Wi-Fi radio_test utility to set PTA parameters (Wi-Fi band, antenna mode, SR protocol type), enabling finer radio coexistence testing. Commit 5f611eb6232052989cc6636a64008ec1c5d0d512 documents the change. Business value: improves test coverage, speeds validation of multi-radio scenarios, and reduces risk of interference in devices using Wi‑Fi and SR radios. Technologies demonstrated: embedded CLI design, PTA/coexistence concepts, version-controlled feature development. No major bugs fixed in this period.

Month: 2024-12 — Focused on stabilizing NRF7002DK radio coexistence under Zephyr RTOS by correcting GPIO ownership. Key fix ensures CPUAPP owns and forwards shared radio coexistence GPIOs, addressing SR coexistence breakage. Implementation is captured in commit c459033addf4d461ca4a721d290f034763609603 with message "boards: nrf7002dk: Fix SR coexistence GPIOs ownership".
