PROFILE

Simon Duquennoy

Over three months, this developer enhanced cloud-ready networking and WiFi integration for the nrfconnect/sdk-nrf repository, focusing on the nRF7120 platform. They unified network and WiFi configuration across AWS and Azure IoT samples, streamlined TLS and MbedTLS settings, and improved runtime robustness by refactoring the nRF Cloud sample for WiFi-centric use. Their work included fixing memory handling in WiFi drivers, resolving MQTT TLS handshake issues, and implementing retry logic for CoAP clients under contention. Using C, CMake, and YAML, they consolidated configuration management, improved observability through enhanced logging, and removed legacy board support to reduce maintenance and future-proof the codebase.

May 2026 monthly summary focusing on key accomplishments, business value, and technical outcomes for sdk-nrf. The main thrust this month was completing a strategic WiFi-centric transition of the nRF Cloud sample to accelerate WiFi product integration, while strengthening runtime robustness in network operations. The work delivered a cleaner, more maintainable codebase with clear ownership, enabling faster feature delivery and reduced maintenance overhead. Overall, the month delivered two major streams: (1) a WiFi-focused refactor of the nRF Cloud sample with deprecation of the cellular variant, and (2) targeted stability improvements in the CoAP client under contention, improving resilience in production scenarios.
