Particle Tools Changelog


11/16/16 - Integration rate limit visibility

You now have the ability to see specific integration errors related to rate limiting in the audit logs for integrations on the Console! This can help you more accurately diagnose potential issues with your integrations in production.


11/17/16 - Updated CLI Installer for Windows

The CLI installer for Windows has been improved. The CLI that is installed will now automatically update to new CLI versions, and also includes a build of OpenSSL, which is required for some advanced CLI features like key generation (particle keys new and particle keys doctor, for example).

To download the new CLI installer, visit this download page.


11/25/16 - Firmware version detection and automatic device status updates in Build IDE

Since its release, Electron users were able to see what firmware version is running on their devices from tools like Build IDE. Now this feature is also available for Photons, P1’s and some compounds like Bluz.

The same information can be also fetched using API when listing devices.

We also made two changes in Build IDE:

  • improved how device connectivity status is being refreshed, making it more reliable and responsive.
  • removed Electron online icon as it was misleading due to nature of cellular connection

Firmware v060 has been released for all Particle devices. This is a huge update to our system firmware that comes with a ton of new features and bug fixes.

The biggest feature is a brand new logging library for flexible system and application logging. Docs for the improved logging system can be found here. For a full list of improvements, please check out our Particle Firmware Updates Thread or GitHub page for v060.

Photon devices will be automatically updated when new firmware is flashed to the device, and Electrons can be manually updated by downloading and running the system updater feature in our Firmware Manager tool.


12/2/16 - Azure IoT Hub Integration (beta)

We’re excited to announce Particle’s next 1st class integration with Azure IoT Hub. Acting as the “front door” to Azure, streaming from Particle into IoT Hub will make it easy to forward device data onto any of Azure’s products to add intelligence and robustness to your IoT product or application.

For more information on how to get started, check out the docs on the IoT Hub integration. This integration is being released as a beta.


12/12/16: Azure IoT Hub Custom Data Payloads

After feedback from early users of the new IoT Hub integration, you now can customize the JSON payload that gets sent to Azure when a device triggers the integration. This will help make it easier for downstream Azure applications to consume the data that enters IoT Hub. To customize the payload, click the “Advanced Settings” link when creating the integration, and put your JSON into the code editor:


12/14/16: Instructions for local compilation

1/26/2017: SIM management for products

A big announcement today! For Particle product creators building cellular-connected devices, seamlessly managing a fleet of SIM cards becomes increasingly important as you grow. Today, we launched SIM management for products, equipping you with another useful tool that makes it even easier to go from prototype to production when using the Electron in your deployment.

Some of the most valuable features of SIM management for products include:

  • Import and pre-activate SIM cards en-masse to ensure a smooth unboxing experience for end users of your products
  • Gain meaningful insights into data usage patterns by viewing fleet-wide usage information
  • Set sensible cellular defaults to save you time and effort without sacrificing control of individual SIM cards
  • Take advantage of volume-based pricing for cellular service available exclusively to product creators

This feature is being launched in public beta. For more information on how to get started, check out the guide on our docs!


1/31/2017: Build Quick Help Drawer

Hello friends! Today we’ve added a new item in the Build sidebar, because we know that sometimes it can be hard to understand how a device is feeling.

Clicking on it brings up the new Quick reference drawer. It will show you all the device modes (docs), so you can quickly figure out in which state your device is currently in.

Hopefully it will help and will reduce some time going back and forth to the docs!


2/2/2017: Preprocessor improvements

Here’s something new to make sure every day doesn’t feel like groundhog day: you can now use custom classes in your code on the Web IDE and you will no longer get tripped up by if else(foo).

class X {
// no longer says X does not name a type
void doit(X &x) {
bool foo, bar;
void setup() {
  X x;
  if (bar) {
  // no longer confuses else if(foo) with a function declaration...
  else if (foo)

2/7/2017: Bug fixes and improvements to the Web IDE

We care a lot about the way that our tools help you achieve your goals and we know that sometimes the experience can be affected by bugs. This sprint we knocked some off and also added some small improvements.


  • Fixed: Users could change selected device when a flash was in progress. Sometimes, in a rush, users changed their starred device during a flash, and this caused some minor confusion. You will see a modal if you try this now, so hopefully, no more confusion around.
  • Fixed: Claiming a device is broken in the Web IDE, as it also loads products. After claiming a device, the list of products was loaded in the list of devices. This doesn’t happen anymore, now only your cool new device :sunglasses: will be added to the list.
  • Fixed: Remember last code a user had open, reopen when they return We want you to be able to get back to your code fast, so after opening an app, next time you go to, you will be presented with the last app you’ve opened.
  • Fixed: Refresh devices doesn’t show newly claimed devices Claim a device through the CLI or the API? We’ll make sure it shows up when you hit the refresh button in the Devices sidebar.
  • Improved: Device selection Previously, if you deselected the active device, flash and verify were disabled until you selected a new one. You must now change your device target to another device to “un-select” the original one.
  • Improved: Console menu item now directs to /logs. Need a quick sneak peek of what your device is telling to the world? Click on the Console icon and we will show you. Not seeing anythings in the logs? Make sure you’re publishing events.


2/7/16 - New FAQ on Eclipse Debugging

There is a new FAQ that describes how to use Eclipse, a free IDE for Windows, Mac, and Linux, along with OpenOCD, to do source-level debugging of code running on a Particle Photon, P1, or Electron.
Some of the things you can do:

  1. Set breakpoints in code and view source.
  2. See the call stack.
  3. View variables.
  4. Single-step through code.


2/8/2017: Docs: webhooks and search

There is a new webhook reference section in the docs that documents all the properties of webhooks and the template syntax.

The search box at was revamped to remove all the duplicate results for multiple devices and provide more accurate results.

This is also available on which is currently serving docs for 0.6.1-rc.2 firmware.
