Developing with Zephyr: Introduction – powered by Zephyr Project
March 11, 2025; 11:00 am – 11:30 am
What’s in a Name: Is Zephyr Really (Just) an RTOS? Benjamin Cabé, Developer Advocate, Zephyr Project
What more and more people now simply call “Zephyr” is officially branded as “Zephyr RTOS”. But is it really _just_ an RTOS? Zephyr offers more than just an RTOS kernel; much like it would be unfair to compare the Linux kernel to a full-blown distribution such as Ubuntu or RHEL, Zephyr provides a complete embedded development platform that greatly simplifies the development of portable, hardware-agnostic applications. We’ll explore some of the unique features Zephyr offers that are key to enabling productive development, such as its testing framework, its module and dependency management system that greatly simplifies the provisioning of development environments, and more. If you’re already using Zephyr, this session will help you discover some hidden gems you might have missed. And if you’re still considering Zephyr,we’ll help you see the bigger picture especially if you’re maybe focusing on the “real-time” aspect too much without considering the broader ecosystem.

From Code to Current: Reducing Energy Consumption in Zephyr Device Drivers, Fabian Plug, grandcentrix
When designing battery-powered sensor devices, optimizing the power consumption of all components is crucial. While many sensors offer low-power modes, the generic sensor interface in Zephyr may not always utilize these modes efficiently. In this talk, I will provide an in-depth look at how Zephyr’s Power Management Subsystem works, how to integrate it into your device drivers, and how it can be used to further reduce power consumption. Using examples such as a battery level sensor and I2C sensors, I will demonstrate various strategies to manage and minimize a sensor’s energy usage. There are multiple approaches to integrating power management within the Zephyr operating system, and I will discuss how sensor characteristics influence which method results in longer battery life. Achieving optimal energy efficiency requires careful consideration of several parameters. Additionally, I will cover how to accurately capture power consumption data, explaining why conventional tools like multimeters may not be suitable for this task. Finally, based on the collected data, I will infer device usage patterns and validate the effectiveness of the power management implementation.

Porting a Bluetooth Application to Zephyr OS – Benefits and Challenges,David Egan, Infineon Technologies
The Zephyr OS is based on a small-footprint kernel designed for use on resource-constrained and embedded systems: from simple embedded environmental sensors and LED wearables to sophisticated embedded controllers, smart watches, and IoT wireless applications. Zephyr provides product developers with a software platform that enables re-use of software while keeping the toolchain the same. Once Zephyr OS supports a particular wireless MCU and Bluetooth controller, everything else is abstracted, so software written for Zephyr is hardware agnostic. This paper examines the challenges and benefits of migrating a Bluetooth application to Zephyr OS and supporting it in the future. It also looks at the reasons why the Zephyr environment and development flow might be selected for a project, considering the pros and cons. The main section of the paper chronicles a developer’s journey, starting with setting up a Zephyr development environment and then moving on to porting an existing Bluetooth LE application. It describes the challenges faced and how any challenges are addressed along the way. The resulting paper is a guideline for developers who wish to adopt Zephyr OS for their Bluetooth application.

Testing Embedded Software With Zephyr, Mohammed Billoo, Embedded Software Consultant – MAB Labs, LLC
Testing should be integral to the software development life cycle, especially embedded software. Embedded software engineers should always consider how they will test their implementation at every stage of the development process. They should establish the necessary testing infrastructure before writing even one line of code. Fortunately, The Zephyr Project RTOS contains an extensive testing ecosystem that embedded software engineers can leverage during development. Zephyr has infrastructure for unit testing and integration testing. In this talk, we will learn why testing is especially important for embedded software development and the tools that Zephyr offers to test during each stage of the development process (such as “Ztest” and “twister”). We will see real-world examples and demos of how to implement testing for a Zephyr application, run the tests, and evaluate the generated reports to understand how well we were able to evaluate our application.
Day 2 – March 12, 2025
Qualifying Safe Embedded Systems
March 12, 2025; 10:30 am – 11:00 am
Level up your Embedded Testing Game – Fretish, Robot and Twister: A Dream Team, Christian Schlotter, Carl Zeiss Meditec
Developing embedded software for regulated environments like medical devices presents unique challenges. Crucially, we need to document how the software design fulfills stated product requirements. While functional testing remains dominant for verifying functional suitability, deriving and maintaining effective test suites can quickly become cumbersome. This talk explores a novel approach to this longstanding problem. We leverage NASA’s FRETish method for formally capturing requirements. We will talk about how the formal nature of FRETish requirements allows for automatic test case generation leveraging the Robot Framework. The latter was specifically chosen as it is partially supported by Zephyr’s test harness today and allows to utilize twister for automated test execution of these test suites on real hardware. This method has the potential to streamline testing, offering benefits such as reduced time and maintenance efforts as well as accurate coverage metrics from very early on in the project’s lifecycle. We’ll discuss our progress in implementing this approach, the challenges we encountered, and potential solutions for deeper integration with the Zephyr project.

Navigating the Software Ecosystem for Software-Defined Vehicles: A Multi-OS Architecture Approach, Himanshu Pande, Wind River
As the automotive industry transitions from distributed function-specific systems to centralized computing and software-defined vehicles, a range of operating systems is required to meet diverse and often conflicting needs. Linux and Android, with their flexibility and proven track records in numerous industries, are set to play a key role in future vehicle platforms. However, as vehicle manufacturers deploy applications with increasingly stringent requirements — safety, security, performance, predictability — a more nuanced approach to software architecture is necessary. Real-time operating systems (RTOS), optimized for deterministic latency, will remain essential for safety-critical use cases. In addition, lightweight execution environments like Zephyr offer scalable solutions for constrained devices, while AUTOSAR continues to provide a standardized framework for ensuring interoperability and compliance in embedded automotive software. Together, these components — Linux, RTOS, Zephyr, AUTOSAR, and Android — must complement each other to form a cohesive in-vehicle software architecture that meets the demands of modern automotive innovation. In this presentation, we will adopt the perspective of a software architect, show when and why to use these different solutions, their benefits and limitations, how to combine them (e.g. using modern hardware, virtualization) and how this could apply to other industries.

Remote Zephyr Shell with Golioth // Zephyr Tech Talk #026
2025-07-09 15:00 - 16:00 UTC
Tune in on Wednesday, July 9 (9:00 AM EDT / 3:00 PM CEST) for a new Zephyr Tech Talk live stream!
The Zephyr shell is one of the most underrated features in Zephyr. It can be incredibly useful to quickly interact with hardware and help troubleshoot issues. But what happens when your device is deployed in the field, connected only by a cellular modem? That powerful local shell becomes inaccessible, leaving you flying blind.
Chris Gammell from Golioth will join Benjamin Cabé to discuss all things Zephyr shell, from controlling I2C devices, to regulators, sensors, and more, as well as how to expose it remotely and make virtually any Zephyr device accessible from a web-based shell using Golioth’s cloud and Remote Procedure Calls (RPCs). This episode is a great opportunity to discover shell commands you may not even know exist, and to learn about the challenges of securely interacting with devices in the field.
Zephyr Tech Talks are live streams organized by and for the Zephyr community. Join us live to ask your questions directly to our guests, or catch the recording anytime afterward.
