Troubleshooting Tools

Here are some tools to help you as you troubleshoot your Argon.

Listening Mode Commands

It is possible to put your Argon in Listening Mode to get some information about its system, version, and MAC address, and Device ID. You can even add Wi-Fi credentials with this method.


For Windows

For Windows users, we recommend downloading PuTTY.

Plug your device into your computer over USB. When the Argon is in Listening Mode, open a serial port over USB using the standard settings, which should be:

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

For macOS or Linux

On macOS (OS X) and Linux systems, you can access the serial monitor through the terminal.

For macOS, open the terminal and type:

screen /dev/tty.u

and pressing tab to autocomplete.

On Linux, you can accomplish the same thing by using:

screen /dev/ttyACM

and pressing tab to autocomplete.

Now you are ready to type some commands to get info about your device.

Display MAC Address

To display the MAC address of your device, type m

This will give an output something like:

Your device MAC address is

Get Device ID [deviceID] CLI method

Using the Particle CLI

  • Put your device into Listening Mode mode while being plugged into a computer via USB
  • Issue particle serial identify from the Particle CLI and it should return the deviceID.

Get Device ID

To display the device ID of your Argon, type i

This will give an output that looks like:

Your device id is 1a2345678912345678901234

Display Device OS Version

To get the Device OS (previously called system firmware) version of your device, type v

This will give you an output indicating the firmware that your device is using.

Sample output:

system firmware version: 0.4.6

Display System Information

For debugging purposes, sometimes it helps to get a dump of all the system information. For this, you can press s

The output will be a big confusing mess, which is why most of the time you won't need to use it. Occasionally, though, Particle Support might ask you for it. It looks something like this:


Configure Wi-Fi

You can also configure your Wi-Fi using this method. The key for Wi-Fi configuration is w

The configuration process will be almost identical to the process laid out in the Particle CLI command particle serial wifi

DFU Commands

There are a number of low-level commands that can be used in DFU mode
