February 2026 monthly wrap for nrfconnect/sdk-nrf: delivered architectural refactor to modularize Channel Sounding Distance Estimation (DE) workflow by decoupling RAS-specific processing and introducing antenna-path configurability. Implemented a pure distance estimator DE library with RAS data processing moved into the CS samples, complemented by a new Kconfig to govern the number of antenna paths. This enables reuse across hardware configurations, simplifies testing, and allows running the DE library without direct RAS/CTLR configs. Overall, improves maintainability, testability, and integration ease for antenna-path scenarios.
