Zephyr

The RAK5010 is a cellular board based on Quectel's BG95 modem (Qualcomm chipset). A Nordic nRF52840 microcontroller "runs the show", connecting to the modem via UART. This is a nice combination for a number of applications like remote sensing, application tracking, and Bluetooth <> Cellular gateway. Let's walk through the process of developing for this board in the Zephyr RTOS.

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.

In this post, we'll walk through a couple methods for defining abstract hardware interfaces in Zephyr using...

Golioth works with Qualcomm. The Golioth Firmware SDK, release 0.12.0, supports the Zephyr Modem subsystem. This enables support for more modem technologies, starting with Qualcomm, and support for the Quectel BG95 as a first class cellular modem.

Both Zephyr and Golioth have solutions for keeping track of multiple revisions of your hardware. Let's walk through how to tell Zephyr there is both a "Rev A" and "Rev B" of your hardware. We'll finish up by talking about how Golioth organizes OTA firmware updates for your different board revisions.

Learn how to create a portable Ozone project file that you can check into a git repository for future debugging of Zephyr applications.

We are returning to Embedded World in 2024 (EW24) and will be showing off new Golioth features, as well as end-to-end IoT demos (Reference Designs) at the Zephyr booth and with partners around the fair.

Guest Timon Skerutsch writes about building a tank level sensor using Zephyr from start of his prototype, eschewing tools like Arduino and CircuitPython.
