How To

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.

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.

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.

It's easy to see that Golioth makes firmware updates for internet-connected devices a snap. But combine Golioth Cohorts, our improved OTA event log, and interconnectivity tools like SMP, and you end up with a powerful OTA scheme for all of the controllers in a complex system.

Did you know that Zephyr doesn't have a plain old GPIO example? The closest thing is the blinky example that controls LEDs. Why is that? Zephyr expects you to write your own devicetree bindings. It's not that hard, and it's the topic of today's post.

Learn the ins and outs of the Zephyr driver subsystem and learn how to write your own custom driver APIs the Zephyr way!

WebAssembly runs on microcontrollers, but why would you want to do that? Dan Mangum shows us how to use Wasm with Zephyr RTOS, why you would want to, and he even discuss how to decide if the tradeoffs fit your needs.

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.
