Manufacturing is marathon, not a sprint. Chris Gammell walks through five phases of IoT device production, discussing what’s involved in each step and how Zephyr RTOS can help during his talk from the 2024 Embedded Open Source Summit.
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.
Turn your Bluetooth devices into a connected IoT fleet using Golioth. This post walks through the process of creating a Bluetooth to Cellular gateway and sending sensor data to the cloud.
Pytest is a framework for testing and we use it for our Firmware SDK. This post reviews setting up fixtures that connect embedded projects to pytest.
Golioth’s Firmware SDK (v0.11.0) pulls in recent versions of different ecosystems, allowing developers to target a wide range of custom hardware.
Nordic’s nRF9160 cellular modem includes a great peripheral called the Key Management Unit (KMU). This secure key storage mechanism lets you write keys to it which cannot be read back. However, they can still be used for DTLS authentication. In this video and blog post I’ll walk you through how to use the feature with […]
For more than a year, Golioth has been hosting free Zephyr training. We’re going to keep doing that. But the news today is that you can learn from our Zephyr course anytime, anywhere using Codespaces. Ze…what? IoT devices usually need a real time operating system (RTOS) to handle the networking aspect of connecting things to […]
Over-the-Air (OTA) firmware updates are table stakes for Internet of Things (IoT) devices. Once a device is in the field, OTA means you can make changes by updating the firmware remotely. The ability to update devices remotely is great, but that alone is the bare minimum of functionality. Options for targeting specific devices for each […]
Golioth attended the Hackaday Superconference in 2023 and created a “badge hack” to send images from a tiny embedded device up over a cellular network and display on badgecase.io.
Golioth’s newest Zephyr support is now part of our cross-platform Golioth Firmware SDK. Yes, we have always supported Zephyr. This latest development includes our top-tier Zephyr offering alongside the other platforms we support–all in one single software development kit. We want to hear what you think of the new Zephyr support. Right now we’re in […]
