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.
Golioth has migrated the Zephyr SDK to a new URL and we are announcing the changes to our audience so that developers are prepared for the change.
Golioth is excited to announce our newest output streams integration with Ubidots. Thanks to this partnership, Ubidots data visualization dashboards are now easy to set up using a pre-configured plugin to access your Golioth device data. Here’s how it all works.
Node-RED makes it easy to connect to Golioth using WebSockets and our REST API. With those in place, you can monitor live data from your devices, and control them via updates to LightDB state data.
I needed to build 15 sets of the same firmware, but pass three unique variables for each copy. Zephyr has a solution for this: the Kconfig system. You can declare your own custom symbol, then set the value by passing a command line argument at compile time. Here’s how to do this with your own projects.
With a bit of planning, you can make sure that your IoT devices stay in sync with the cloud and behave in a predictable way for your users. The concept uses a “desired state” that is watched by the device for changes from the cloud. The device then reports back its actual state as a separate collection of data.
Golioth has partnered with Datacake to make it easy to stream data from Golioth devices to beautiful visualization panels on the web. Showcase your IoT data with Datacake!
The Golioth WebSocket plugin is now available in the Grafana Cloud. This post guides you through how to add the plugin to Grafana, how to connect the Golioth WebSocket API, and how to set up a dashboard to visualize realtime the data.
Reassigning pins in your Zephyr project is key to keeping your code portable. This guide demonstrates how to use devicetree overlay files to move peripherals like SPI or i2c to different pins, and how to make sure your new assignments don’t collide with the existing configuration.
Parsing JSON packets with strings and punctuation delimiters doesn’t sound like much fun on a microcontroller. That’s why it’s really nice that Zephyr has a built-in JSON library. In this post and video we show you how to use it on your data from the cloud.
