Free Zephyr Training on July 15th, 2026

Golioth is once again hosting a free Zephyr training, and we’d love to have you join us on July 15th, 2026. You can sign up below or using this link.

Why Golioth does Zephyr training

The Golioth Firmware SDK and our Pouch SDK (which enables indirectly connected devices like Bluetooth nodes) both have ports for the Zephyr RTOS and its broader ecosystem. Zephyr gives us the widest coverage area of any single platform: it runs on hardware from dozens of silicon vendors, supports a huge range of connectivity options, and has a growing community of professional embedded developers behind it. Training more developers on Zephyr directly supports our mission of making connected device development more accessible. We ran our first training at the Zephyr Developer Summit in 2022 and have refined multiple times since then.

How things have changed – Zephyr, LLMs, and Local Shell

Zephyr itself keeps moving fast and that’s saying a lot since we did our last training over a year ago. New major versions have brought improvements to devicetree tooling, expanded board support, and a more robust build system. If you attended one of our previous sessions, there’s genuinely new ground to cover.

LLMs have also changed the way many developers approach embedded development. One year ago, I would be reticent to suggest even the best models with Zephyr; now Claude helps me build some of my demos. We still are teaching you about Zephyr, but now you can likely ask the human trainers or the LLM assistants when you get stuck.

Perhaps the biggest new addition to our toolset is Local Shell, a browser-based tool that communicates with Zephyr devices using the Simple Management Protocol (SMP) over the Web Serial API. It mirrors the capabilities of tools like mcumgr and smpmgr but runs entirely in the browser with no installation required. We published a full writeup on Local Shell recently, it’s a genuinely useful addition for anyone doing Zephyr device management and we had this training in mind when we built it.
