It’s especially useful when debugging nRF9160 Zephyr apps. Sorting out multiple threads and multi image builds can be tough, but this is the tool you want. In […]

Displaying Firmware Version and Battery State with Zephyr

We recently open-sourced the Golioth Reference Design Template that we have been using internally as the starting point for our growing library of reference designs. Out of the box, the template provides an end-to-end working firmware example showcasing all of Golioth’s key features. You can read more about what’s included in the Reference Design Template in […]
