How To

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.

Guest author Chris Wilson explains how a Golioth training inspired him to dig into how to add a new board definition in Zephyr

The ESP32 is a great way to get up and running quickly on Golioth. This article, and the accompanying video, walks through the process of provisioning an ESP32, installing the Zephyr RTOS toolchain, then loading and running your firmware.
