How to Connect Live Golioth IoT Data to Grafana Cloud using WebSockets
The Golioth WebSocket plugin is now available in the Grafana Cloud. This post guides you through how to add the plugin to Grafana, how to connect the Golioth WebSocket API, and how to set up a dashboard to visualize realtime the data.
Pin mapping in Zephyr lets you move pin functions with ease
Reassigning pins in your Zephyr project is key to keeping your code portable. This guide demonstrates how to use devicetree overlay files to move peripherals like SPI or i2c to different pins, and how to make sure your new assignments don’t collide with the existing configuration.
How to parse JSON data in Zephyr
Parsing JSON packets with strings and punctuation delimiters doesn’t sound like much fun on a microcontroller. That’s why it’s really nice that Zephyr has a built-in JSON library. In this post and video we show you how to use it on your data from the cloud.
Debugging Zephyr for Beginners: printk() and the Logging Subsystem
Zephyr has a number of tools to aid in debugging during your development process. Today we’re focusing on the most available and widely useful of these: printing message to a terminal and enabling logging messages. New to Golioth?

How to build your Zephyr app in a standalone folder
If you’re like me, you installed Zephyr and began making your own changes to the sample applications that came with the toolchain. But at some point–either for personal project repository tracking or building out a professional project–your program starts to take shape. You want to move it to its own standalone directory. It’s not immediately […]
How to Set Up ESP32 GPIO Pins in Zephyr
Getting your ESP32 GPIO pins working with Zephyr is easy, and using a devicetree overlay file to do so makes it painless to change pins (or even boards/architectures) in the future. Today we’re looking at a simple overlay file for the ESP32 architecture and talking about the syntax used to choose input and output pins. […]
