During September 2025, Mateusz Kobak developed Modbus integration for the phoenix-rtos/phoenix-rtos-project repository, focusing on expanding industrial interoperability. He updated core libraries and ports using C and shell scripting, ensuring submodule dependencies remained synchronized for reproducible builds and smoother continuous integration. Mateusz also introduced a curl-related flag to support flexible client behavior in Modbus operations, addressing diverse industrial requirements. Additionally, he improved UDP streaming reliability in the smolrtsp component, targeting robust industrial deployments. While the work was concentrated within a single feature, it demonstrated depth in system integration and maintenance, positioning the project for broader industrial adoption and easier downstream integration.
