PROFILE

Marcin Gasiorek

Marcin Gasiorek contributed to the nrfconnect/sdk-nrf and sdk-nrfxlib repositories by developing and maintaining NFC and radio driver features for embedded systems. He implemented dynamic radio reconfiguration, enhanced NFC power management, and improved documentation clarity, using C, CMake, and Kconfig. Marcin addressed critical NFC timing and stability issues by refining driver logic and resetting frame delays to prevent tag rejection. He also managed code ownership transitions and streamlined onboarding through CODEOWNERS updates. His work demonstrated depth in firmware development, robust bug fixing, and cross-team collaboration, resulting in more maintainable code and improved reliability for NFC-enabled Nordic devices.

Work History

April 2026

1 Commits

Apr 1, 2026

April 2026 monthly summary for nrfconnect/sdk-nrf: Focused on stabilizing NFC operations in the NFCT driver to prevent tag rejection during RF field loss. Delivered a targeted bug fix that resets the NFCT frame delay to default, ensuring consistent frame timing for subsequent sessions and improving reader compatibility in real-world deployments.

March 2026 monthly summary focusing on delivering dynamic radio reconfiguration, robust driver APIs, and NFC stability improvements across Nordic NRF stacks. Key outcomes include: (1) NRF 802.154 driver: added a configuration option to inform consumers when reinitialization is enabled, enabling dynamic control in Zephyr applications; (2) 802.15.4 driver configurability and robustness: introduced network parameter accessors (PAN ID, short/alternate/extended addresses), added a reinitialization function, improved NULL-pointer safety in setters, and added a Kconfig option to enable driver reinitialization for dynamic radio configuration changes; (3) NFC TNEP stability: code cleanup by removing an unused define and correcting the waiting time extension assertion to align with documented limits. These changes improve runtime configurability, resilience, and maintainability, reducing debugging time and accelerating feature deployment across devices.

Jan 1, 2026

Month: 2026-01 — Focused on accuracy and maintainability of NFC-related guidance in the sdk-nrf docs. Delivered a targeted documentation correction that clarifies RXERROR is a software bug in the nrfx driver, not a hardware issue, and reorganized the related guidance under the nrfx_nfct driver section. This improved developer onboarding, reduced misinterpretation, and cut potential support overhead. The work aligns with KRKNWK-21227 and nrfx PR #1078, with a traceable commit history.

Dec 1, 2025

Monthly summary for 2025-12 focusing on NFC ownership governance and cross-repo CODEOWNERS updates. Delivered two coordinated ownership changes across sdk-nrf and sdk-nrfxlib, enabling clearer responsibility and faster maintenance for NFC features. Key improvements include transfer of NFC-related ownership to @ncs-radio-sw in sdk-nrf and updating CODEOWNERS to include @ncs-radio-sw for NFC in sdk-nrfxlib. This reduces onboarding time, accelerates issue resolution, and strengthens accountability. Technologies used include CODEOWNERS management, git-based collaboration, and cross-team coordination. Business impact: improved maintainability, faster feature iterations, and reduced risk of orphaned NFC code.
