LPWAN – Mioty® Module Firmware
The mioty® m.YON module from Swissphone is a compact IoT endpoint module for robust LPWAN communication, which is ideally suited for industrial and large-scale sensor networks thanks to its high resistance to interference.
Arendi integrated the mioty® Stack (Fraunhofer IIS) into a Zephyr-based firmware and implemented the host connection and the multistage bootloader. This gave Swissphone a reliable and quickly integrable firmware base.
“For the development of our m.YON module, we needed a partner who had a thorough understanding of the sophisticated mioty® technology and the Zephyr ecosystem. Arendi not only seamlessly integrated Fraunhofer's stack, but also implemented the critical host interfaces and the bootloader with exceptional robustness. As radio specialists, their deep embedded expertise completely won us over – a real boost for our project.”

Initial situation, goals & challenges
For the implementation of the highly innovative mioty® radio standard in the m.YON IoT module, Swissphone relied on Arendi as a leading technological development partner – building on a long-standing partnership in other MCU-related firmware projects.
The challenge lay in seamlessly integrating the complex Fraunhofer mioty® stack into a highly efficient, Zephyr-based embedded firmware system. At the same time, the host interfaces (SPI/UART) and a completely fail-safe multi-stage bootloader concept for future over-the-air (FOTA) updates had to be designed and implemented from scratch to guarantee maximum stability in license-free, interference-prone radio environments.
Project results & customer benefits
The collaboration resulted in a robust, production-ready firmware platform that transforms the m.YON module into a ready-to-use, plug-and-play solution for industrial IoT applications.
By combining all critical embedded disciplines—from low-level stack integration and comprehensive automated test integration to a secure update mechanism—time-to-market was significantly reduced and technological project risk minimized.
