Zephyr’s west meta tool can perform a vast number of useful operations. Here’s a collection of both command and uncomon commands that we find ourselves reaching for when working on Zephyr-based IoT projects.
Allure Report is an open source tool to better understand testing outcomes. Golioth runs over 500 Hardware in the Loop tests for each pull request. Here’s how we use Allure Report to make sense of it all.
Zephyr configuration that is specific to the chip, not just the board itself, can be centralized in your application. This means less duplication of configuration options across your IoT board definitions which improves both readability and maintainability of your code.
Both Pytest and Twister (Zephyr) can already product JUnit XML formatted test summaries. You can use these files to publish a very handy summary table for all of your continuous integration (CI) tests on GitHub.
Zephyr’s west manifest system includes an allow-list to filter dependencies from upstream libraries (like the Zephyr tree itself). Use it to tightly control what libraries your projects use, and to stop checking out way too many unused code.
Uploading audio from IoT devices to the Cloud is easy with Golioth. Here’s everything you need to know to deliver large chunks of data from your fleet to whatever cloud service you desire, all with just one API call and one callback function.
This post walks through how to upload images from IoT devices to Golioth over CoAP using block upload. Once the image is at the server, Golioth Pipelines can route the data to the destination of your choice!
Golioth enables AI applications by pushing TF Lite model updates directly to devices. These can be stored locally and begin running without a device restart. This example showcases the Golioth SDK running on ESP-IDF.
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.
