Device Management & Ownership

How do I find my device ID?

There are several ways to find the device ID of your Core, but the best method depends on whether or not your Core has already been claimed to your account. We'll cover both scenarios in the section below.

Note: You do not need to know your Core device ID to complete setup using the Particle smartphone app or over USB! The Core device ID is most useful for debugging with the technical support team and building interactions with your Core through the Particle API.

1. I haven't claimed my Core yet!

If you haven't claimed your Core yet, there are two ways for you to figure out your Core device ID:

1a. Get your Core ID using the Particle CLI Make sure that you've got the Particle Command Line Interface (CLI) installed by typing particle into your terminal. You should see a help message that displays the various commands available to you. Please make sure your Core is in Listening Mode (flashing blue), and type particle serial identify.

Your Core should respond with it's Core device ID!

1b. Get your Core device ID using CoolTerm, PuTTY, or screen CoolTerm and PuTTY are programs for Mac and Windows, respectively, that allow you to communicate with your Core using the exposed serial lines. You can find the download links for CoolTerm and PuTTY at the links attached-- CoolTerm & PuTTy.

Plug your Core into your computer over USB. When the Core is in Listening Mode (flashing blue), open a serial port over USB using the standard settings, which should be:

  • Baud rate: 9600
  • Data Bits: 8
  • Parity: none
  • Stop Bits: 1

Once you've successfully opened a serial connection, you have two commands at your disposal by hitting either w or i on the keyboard. Here's what they do:

  • w: Set up your Wi-Fi SSID and password
  • i: ("i" as in identify) Read out the Core device ID

2. I've already claimed my Core!

If you've already claimed your Core, finding your Core device ID is a super simple process. You can still use either of the methods described above, but the easiest method is to look up your Core device ID in the Particle Build IDE.

Follow these simple steps:

  • Navigate your web browser to the Particle Build IDE.
  • Click on the "Core" icon in the bottom of the navigation pane
  • Find the Core whose device ID you'd like to know, and click on the dropdown arrow on it's right
  • The Core ID will be displayed in a box that reads, "device ID"

Great! Go forth with your Core device ID and prosper.

How do I transfer my Core?

1. Remove the Core.

Remove the Core from the account it was previously registered to, using the Particle Build IDE or Particle CLI.

2. Connect the Core

Make sure that the Core is connected to the Particle Device Cloud (breathing or pulsing cyan).

Note that a Core cannot be claimed unless it is connected to the Particle Device Cloud, and is breathing/pulsing cyan.

3. Claim the Core

Claim the Core using the Particle smartphone app, Particle Build IDE, or Particle CLI.

"Can Particle do this for me?"

Excellent question! No.

We take security extremely seriously at Particle, and that means being very sensitive to attempts to steal, hack, takeover, or misuse Cores and Particle Accounts. As a security feature for all of our customers, we require that requests to add, remove, rename, or reconfigure Cores be submitted directly by the users to whom they are registered.

If you really are the owner of your Core, and are having trouble logging into your Particle account or configuring your Core, send us an email at [hello @ particle dot io], and our Troubleshooting staff would be happy to help you resolve the issue.

How do I unclaim a Core ?

There are two primary ways to remove a Core from your account--using the Particle Build Web IDE, or using the Particle Command Line Interface (CLI).

Using Particle Build

  1. Login to your Particle account at the Particle Build IDE home page

  2. Click on the "Devices" icon in the bottom left-hand panel

  3. Identify the Core that you'd like to remove from your account, either by the familiar name you gave it when you added it to your account, or it's device ID.

  4. Click on the arrow next to the device you'd like to remove, and click the blue "REMOVE DEVICE" button

Using the Particle CLI

1. Install CLI. Make sure you've got the CLI installed by typing

particle help

into your terminal. If you're presented with a list of commands, the CLI is installed correctly. If not, please see the following article:

Installing the Particle CLI

2. Login. Make sure you're logged into your Particle account by typing

particle login

and successfully completing the command line prompts.

3. Remove Core. In your terminal, type

particle device remove <name>

where is either the familiar name or device ID of the Core you'd like to remove from your account. Here's an example:

particle device remove 0123456789ABCDEFGHI


particle device remove pinky_panda

4. Confirm Removal. Confirm that you really want to remove the Core from your account by entering "yes" when prompted by the CLI.

That's it! The Core has now been disassociated with your account, and is once again available to be claimed.
