Today we’re announcing a new C library for fetching Environment Variables: Notecard Environment Variable Manager.

The library offers functions for retrieving Environment Variables from Notehub, as well as “watch variables” that allow you to watch for variable updates at a configurable interval.

The Notecard Environment Variable Manager is open source and available on GitHub. Give it a shot and let us know what you think.

Today we released a Postman Collection that makes it easy to perform Notehub API requests.

The Collection allows you to easily authenticate, pick the request you’d like to use, and make the appropriate call with the click of a button.

To get started today check out our Postman Collection documentation on blues.dev.

A new version of note-arduino, our official library for interacting with the Notecard in Arduino projects, is now available.

The 1.4.0 release includes updated support for multi-threaded applications, and provides new sendRequestWithRetry and requestAndResponseWithRetry methods to overcome hardware race conditions on cold start.

Check out the full changelog in GitHub, and follow our installation instructions to start using the new version in your favorite editor.

A new developer release of the Notecard firmware, version 5.1.1, is now available. The release includes a number of new features, such as the ability to perform asynchronous web requests, a way to schedule host firmware updates and host restarts, and some improvements to the status messages from the hub.sync.status request.

And more! Check out the release’s full changelog for more details, and when you’re ready, install the update on your devices from Notehub.

Today we’re announcing a new Notehub feature: the ability to add devices to multiple fleets, as well as additional tooling to help manage fleets on your devices.

You can see this in action on a device’s page, where there’s a new widget for managing fleets on individual devices.

Try it out and let us know what you think!

Today we released our first batch of app accelerators, and they’re available for you to check out and use at blues.dev/accelerators.

Accelerators are fully documented reference applications for assembling Notecard- and Notehub-powered solutions. Each accelerator provides a complete walkthrough, includes a full list of the hardware you need, and is free to copy, fork, and build upon. Check them out!

We’re happy to announce note-zephyr, a new official SDK you can use to communicate with the Notecard in Zephyr applications.

If you’re new to Zephyr, the note-zephyr SDK’s documentation shows you how to build a new Zephyr project from scratch, including how to install all the underlying dependencies on Windows, macOS, and Linux. If you’re a Zephyr veteran, the docs show the steps you need to take to work with the Notecard in an existing Zephyr app.

Try it out, and let us know what you think!

Today we’re happy to announce Notehub JS—a new library that makes it easier than ever for you to interact with the Notehub API when building custom JavaScript applications.

The library is available to use in all modern JavaScript environments and includes extensive documentation, JavaScript-based code examples of every API call, and ES6-forward syntax.

Learn more on our blog, or check out the library’s documentation to get started building.
