PROFILE
Guillaume Legoupil
Guillaume Legoupil developed ZigBee connectivity for NXP hardware by integrating the IEEE 802.15.4 MAC middleware into the Zephyr HAL and nrfconnect/sdk-zephyr repositories. He merged the 25.09 release of the MAC middleware with ZigBee support, added BLE controller and host libraries for MCXW71 and MCXW72 devices, and introduced a new configuration option to enable NXP MAC integration in Zephyr builds. Using C and CMake, Guillaume updated build systems and connectivity frameworks to align with MCUXSDK 25.09, expanding device interoperability. His work demonstrated depth in embedded systems, firmware, and network protocols, enabling maintainable ZigBee support for future NXP products.

Nov 1, 2025Month 2025-11: Delivered ZigBee connectivity enablement for NXP via IEEE802154 MAC in MCUX SDK within nrfconnect/sdk-zephyr. Implemented configuration to pull up MCUX components for NBU and integrated ieee-802.15.4 MAC with MCUX SDK 25.09.00 BLE controller support (MCXW71/MCXW72). Updated connectivity framework and HAL integration to align with MCUXSDK 25.09.00 release. This work extends NBU device connectivity options to ZigBee and improves interoperability for MCUX BLE controllers, reducing time-to-market for ZigBee-enabled products. Demonstrated proficiency with C drivers, Zephyr, MCUX SDK, West tooling, and cross-repo integration.
