Custom Board, Custom Zephyr Devicetree (AirTag Session 3)

Sign up for the AirTag Clone webinar series to watch Golioth build out board definition files for the Orleon board, a Bluetooth sensor platform/playground. The upcoming session on May 23rd will walk through setting up all required build files.

Battery Monitoring with Zephyr’s Fuel Gauge Subsystem

Fuel gauge ICs offload effort when it comes to taking reliable battery readings and estimating charge and drain times. Zephyr's support for these components makes using them even easier.

How to Sniff Cellular Packets with a Nordic nRF91

Sniffing network packets from a cellular modem is actually pretty easy. It only seems daunting because at first glance you're left wondering how to acquire the packets. Nordic's nRF91 modems have a trace capability that can be used to pipe packets from the device into Wireshark over a USB connection. Here's how to use it.

Bringing the SIM7080G modem module to Golioth

The SIMCOM SIM7080G is a Cat M1 / NB-IoT modem that focuses on low power applications. We tested out the modem using Zephyr's subsystem to connect to the Golioth Cloud.

Spring Cleaning with Golioth: Dust off your Zephyr skills in April 2025

Spring is a time of renewal, growth, and fresh starts—and your IoT projects deserve some spring cleaning, too! Dust off those ideas sitting idle, sharpen your embedded development toolkit, and join us for a free Zephyr RTOS Training on April 30th, 2025.

Useful Zephyr Shells for IoT Development

The Zephyr shell subsystem will help you directly interact with and troubleshoot your IoT hardware. This post details our most commonly used commands, as well as a listing of all Zephyr shell modules that we could extract from a recent project.

Guide to Securely Store Credentials on an nRF91 Modem

The Nordic nRF91 modems include secure storage for TLS credentials. This may be used to authenticate with Golioth. The assets are stored separately from the firmware, and once written, they cannot be read back from the device. This guide shows the process of storing and using credentials.

How to Add Golioth to an Existing Zephyr (or NCS) Project

Golioth removes the pain of connecting constrained devices to the cloud. This post shows you how to add Golioth to your existing Zephyr project and get your first device connected.
