François Michel developed OTNS integration for the zephyrproject-rtos/openthread repository, enabling seamless workflows between OpenThread RCP and OTNS for end-to-end validation and simulation-based testing. He introduced the mOtns attribute to the Instance class when OPENTHREAD_RADIO is enabled, expanded the RCP build to include new OTNS utilities, and implemented selective compilation to ensure only necessary functions are included in RCP mode. By guarding IPv6-dependent features, François improved build reliability and runtime stability. His work, using C++ in the context of embedded systems and network programming, addressed integration friction and enhanced the maintainability of OTNS-enabled RCP development paths.
October 2025 Monthly Summary for zephyrproject-rtos/openthread: OTNS integration with OpenThread RCP completed, enabling seamless OTBR-to-OTNS workflows and end-to-end validation. Key technical work includes adding mOtns attribute, expanding the RCP build with src/core/utils/otns.cpp, and implementing selective compilation so only necessary functions are included in RCP mode. IPv6-dependent features were guarded to avoid build/runtime issues, and OTNS-related events are now emitted from the radio layer to support OTNS workflows. This work, anchored by commit 6d93c7fc9646514267d6c04bd93c99995f7b6cac, reduces integration friction, accelerates simulation-based testing, and improves build reliability for OTNS-enabled RCP paths.
