July 2026: Delivered core NRF RPC enhancements in sdk-nrf with a focus on reliability, maintainability, and test robustness. Implemented NRF RPC OS event reset support and aligned nrfxlib dependencies to ensure consistent header definitions across the stack. Introduced a multithreaded mock framework for NRF RPC/OpenThread RPC, replacing the single-thread wrapper with a dedicated callback thread and making tests thread-safe with configurable stack size/priority. Updated tests to exercise concurrent transport paths and explicit expectations, improving resilience under stress and production-like workloads. Established stronger integration with nrfxlib and validated end-to-end readiness for inter-processor communication.

June 2026 monthly summary for nrfconnect/sdk-nrfxlib: delivered a critical race-condition fix in NRF RPC receive path to improve reliability of packet processing when using auto-free receive buffers. This patch ensures decode_done_event is reset, aligning with event_wait semantics and preventing stale state from causing missed or stalled packet processing.
