Storing Golioth credentials on the nRF9160 using TLS Tags

Nordic’s nRF9160 cellular modem includes a great peripheral called the Key Management Unit (KMU). This secure key storage mechanism lets you write keys to it which cannot be read back. However, they can still be used for DTLS authentication. In this video and blog post I’ll walk you through how to use the feature with […]

Zephyr Training is now Anytime, Anywhere thanks to Codespaces

For more than a year, Golioth has been hosting free Zephyr training. We’re going to keep doing that. But the news today is that you can learn from our Zephyr course anytime, anywhere using Codespaces. Ze…what? IoT devices usually need a real time operating system (RTOS) to handle the networking aspect of connecting things to […]

Understanding Golioth OTA Firmware Updates

Over-the-Air (OTA) firmware updates are table stakes for Internet of Things (IoT) devices. Once a device is in the field, OTA means you can make changes by updating the firmware remotely. The ability to update devices remotely is great, but that alone is the bare minimum of functionality. Options for targeting specific devices for each […]

Automatically Detecting Boards for Hardware-in-the-Loop (HIL) Testing

Golioth is an IoT company that supports as much custom hardware as possible: a multitude of microcontrollers and many different connection types. This presents a challenge when testing on real hardware. We developed tooling that tests the Golioth Firmware SDK on actual boards. Known as Hardware-in-the-Loop (HIL) testing, it’s an important part of our CI […]

Join our free Zephyr training on October 25th at 9am Pacific time to get yourself up to speed. What Will I Learn? This […]

How to turn Helper Code into a Zephyr Module

Embedded developers always maintain sets of helper code that get used across multiple projects. With Zephyr RTOS, you can easily turn your helper code into a portable Zephyr module. Creating a Zephyr module means you can version control your code, making changes in one centralized place, while targeting a specific git commit, tag, or branch […]
