Two new Notecard firmware versions are now available: 11.1.1, our latest developer release, and 10.1.1, a release candidate of our upcoming 10.x LTS.

Both versions include initial support for Notecard for Skylo, support for Notecards with Telit Midband (LTE Cat-1 bis) modems, numerous NTN improvements, and more.

The full release notes are available in the Notecard Firmware Updates documentation. To update your devices, see Updating Notecard Firmware. 

A number of new Notehub features are live and ready for you to test today:

• Data usage reports: We've made it even easier for you to track and report on both data and event usage (with trends!) Look for new charts on your device’s Usage tab.
• Watchdog events: Notehub can now proactively alert you when a device has gone quiet for longer than expected at the fleet level.
• There also a new Snowflake route, improvements to how we handle host firmware management, and new ways of testing JSONata transforms.

Read through The Latest from Notehub for a rundown of all the new features.

Today we're excited to introduce the beta release of Blues Expert, an MCP (Model Context Protocol) server. Blues Expert turns your LLMs (Large Language Models) into a virtuoso that understands the Notecard & Notehub APIs, best practices, and can help you build Notecard-based IoT applications faster and with greater confidence.

Read our announcement blog post or watch our video tutorial to get started.

Today we’re excited to introduce personal access tokens for authenticating with the Notehub API.

With this update, you can create and manage up to 10 tokens from a new API Access section in the Notehub user interface. When creating tokens, you can optionally set an expiration date, and at any time you can suspend or delete tokens as needed.

Personal access tokens carry the same permissions as your Notehub user account, so treat them with the same care as you would a password or other sensitive material.

If you’re previously used the Notehub API’s /auth/login endpoint to create access tokens, those tokens will automatically appear in your personal access token list. If you’ve previously created more than ten tokens, only the 10 most recently used will remain, and the rest will be removed. Notehub’s /auth/login endpoint has been deprecated since 2023, and we plan to remove the endpoint on December 1st, 2025.

Learn more about personal access tokens in Authentication with Personal Access Tokens, and if you have any questions about this change feel free to reach out in our community forum.

Two new Notecard firmware versions are now available: 9.2.3, our latest developer release, and 8.2.2, an updated release in the 8.x LTS series.

Both versions include a new max argument for the note.add request, a new file.clear API, a new sync argument for the var.set request, along with various bug fixes and minor improvements.

The full release notes are available in the Notecard Firmware Updates documentation. To update your devices, see Updating Notecard Firmware. 

Today we’re happy to announce the availability of our new “Midband” Notecard Cellular, based on the LTE Cat-1 bis protocol. Midband Notecards use less power and are less expensive than our Wideband Notecards, use a single antenna design, and are supported everywhere LTE is already available.

We can’t wait to see what you build with them. Read more about LTE Cat-1 bis on our developer blog, and then pick up a midband Notecard Cellular in our shop today.

A new developer release of the Notecard firmware, version 9.1.1, is now available.

The new version includes support for variable-length numeric arrays in Note templates, numerous reliability and efficiency improvements, and a variety of bug fixes.

The full release notes are available in the Notecard Firmware Releases documentation. And if you want to update to the new version, check out our documentation on Updating Notecard Firmware.

The latest LTS Notecard firmware is now available on Notehub! Full release notes and manual upgrade instructions can be found in Notecard Firmware Releases.

We're happy to invite all Blues developers to test their knowledge of Notecard, Notehub, Swan, and more by completing the Blues Developer Certification assessment. For developers, getting certified demonstrates a command of device-to-cloud solutions, data connectivity, and the Blues ecosystem. Learn more here!

Today we’re pleased to announce the release of Mojo, a new way to measure energy usage in battery-powered systems. Built around the low-power LTC2959 coulomb counter from Analog Devices, Mojo provides charge and current measurement at 1% accuracy—giving developers a clear view of battery performance, state, and health in remote deployments.

You can learn more about how Mojo works with Notecard in this release blog post. Once you have the basics down, you can pick up a Mojo in our shop and then try our new quickstart tutorial.
