TL;DR: we've enabled people to compile Zephyr programs from a computer with no toolchain installed, almost instantly. Part...

We often use Grafana for visualizing data from IoT devices. We even wrote a WebSockets plugin for the platform that makes sure you can graph your live data as soon as it arrives on Golioth. But our REST API is also useful with the Grafana platform for visualize historic data.

Golioth showcases how to use SEGGER J-Link, Ozone, and SystemView to optimize your Zephyr programs and dig deeper into Real Time Operating Systems.

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.

Microsoft has finally added USB support to WSL and I’ve been testing this long-awaited feature as part of my Windows development workflow. Today I will walk you through the basic steps of programming an embedded device over USB using WSL.

What if your IoT firmware deployments happened automatically just by typing 'git push'? Lead Engineer Alvaro Viebrantz talks about a sample project that compiles and delivers firmware to eligible devices automatically using Golioth and GitHub Actions.

The ESP32 can be used as an AT modem. This approach makes it really easy to add an internet connection to devices that normally don't have one, like the Nordic nRF52840DK.

Sometimes you don't have extra pins for TX/RX, the UART is already in use, or you don't want to upset critical timing by printing out messages. Real Time Transfer (RTT) is perfect in these situations. It uses the J-Link programmer to transfer console debugging output, without getting a UART involved at all. Good news, it's easy to use with Zephyr!
