Golioth showcased at Embedded World 2022
See the Goioth IoT hardware demos at Embedded World next week in Nuremberg, Germany. You’ll find us with the Zephyr Exhibits in Hall 4.

Zephyr quick tip: Show what menuconfig changed and make changes persistent
Menuconfig allows you to search, select, and enable features in Zephyr with ease. What happens when you want to save your configuration? This post shows you how.
How to use Zephyr shell for interactive prototyping with I2C sensors
The Zephyr interactive shell makes it really easy to test out i2c devices before writing any code. This demo shows how to scan for i2c addresses, issue commands directly, and use the sensor shell to poll your devices for all sensor channels available as part of Zephyr’s sensor subsystem.
Zephyr does Ethernet Too!
Ethernet support is built in to Zephyr with several different chipsets to choose from. Here’s how to add a W5500 Ethernet chip to your project and configure the Zephyr drivers to use it.
New Feature: Updating Zephyr settings from the device shell and more!
Now you can set your Golioth credentials from the Zephyr device shell. You also have the option to pull them from the Golioth cloud and automatically send them to the device from a single command on the command line. These new features use the Zephyr settings subsystem where they are stored in flash memory so that they persist after rebooting.
Golioth Zephyr SDK gets a name change and looks to the future
Golioth has migrated the Zephyr SDK to a new URL and we are announcing the changes to our audience so that developers are prepared for the change.
New Feature: Visualizing IoT Data Using Ubidots
Golioth is excited to announce our newest output streams integration with Ubidots. Thanks to this partnership, Ubidots data visualization dashboards are now easy to set up using a pre-configured plugin to access your Golioth device data. Here’s how it all works.
How to use Node-RED to control IoT Devices on Golioth
Node-RED makes it easy to connect to Golioth using WebSockets and our REST API. With those in place, you can monitor live data from your devices, and control them via updates to LightDB state data.
Add Custom Kconfig Symbols in Zephyr
I needed to build 15 sets of the same firmware, but pass three unique variables for each copy. Zephyr has a solution for this: the Kconfig system. You can declare your own custom symbol, then set the value by passing a command line argument at compile time. Here’s how to do this with your own projects.
Better IoT design patterns: Desired state vs. actual state
With a bit of planning, you can make sure that your IoT devices stay in sync with the cloud and behave in a predictable way for your users. The concept uses a “desired state” that is watched by the device for changes from the cloud. The device then reports back its actual state as a separate collection of data.
