Build Before Installing: Zephyr Dev Environment Using GitHub Codespaces

Golioth Firmware Engineer Mike Szczys describes how we use GitHub Codespaces and Development (Dev) Containers to train engineers all over the world without any install required. Answering the question of how fast can a new Zephyr RTOS user go from zero to successful code compilation.

How to use the RAK5010 cellular dev board with Zephyr

The RAK5010 is a cellular board based on Quectel's BG95 modem (Qualcomm chipset). A Nordic nRF52840 microcontroller "runs the show", connecting to the modem via UART. This is a nice combination for a number of applications like remote sensing, application tracking, and Bluetooth <> Cellular gateway. Let's walk through the process of developing for this board in the Zephyr RTOS.

How to localize your devices with GNSS, NMEA, and Zephyr

Guest author Jerónimo Agulló goes over the basics of GNSS and how the NMEA0183 set of messages standardizes communication between geolocation modules and microcontrollers. Then he shows how a new system in Zephyr makes it easier than ever to set up communication.

Abstract hardware interfaces in Zephyr

In this post, we'll walk through a couple methods for defining abstract hardware interfaces in Zephyr using the devicetree. You've probably seen abstract hardware interfaces implemented on popular development boards. Many boards provide a…

Bluetooth Gateways with Golioth and Zephyr

Turn your Bluetooth devices into a connected IoT fleet using Golioth. This post walks through the process of creating a Bluetooth to Cellular gateway and sending sensor data to the cloud.

Golioth was at Embedded World 2024

As we described in our announcement post, we had a range of demos at our kiosk in the Zephyr Booth at Embedded World 2024. Once again this conference proved to a valuable opportunity to connect with engineers across industries and get feedback…

Golioth Firmware SDK Latest Release Adds Support for Zephyr’s New Modem Subsystem and Qualcomm

Golioth works with Qualcomm. The Golioth Firmware SDK, release 0.12.0, supports the Zephyr Modem subsystem. This enables support for more modem technologies, starting with Qualcomm, and support for the Quectel BG95 as a first class cellular modem.

Managing board revisions in Zephyr

Both Zephyr and Golioth have solutions for keeping track of multiple revisions of your hardware. Let's walk through how to tell Zephyr there is both a "Rev A" and "Rev B" of your hardware. We'll finish up by talking about how Golioth organizes OTA firmware updates for your different board revisions.

Automated hardware testing using pytest

Pytest is a framework for testing and we use it for our Firmware SDK. This post reviews setting up fixtures that connect embedded projects to pytest.
