If giving your roaster credentials through the ROEST Wi-Fi Setup or Particle app fails, you can try with the Windows command prompt, or the Terminal app on Mac computers.

Requirements:

Computer
USB-B or USB-micro

Step 1: Download the cli tool

For windows: Windows CLI installer

For Mac/Linux: Installing CLI on a Mac

Step 2: Connect to the roaster with a usb

Connect the PCB/roaster with the USB. (Either at the back of the roaster with a USB-B type or directly to the PCB with a Micro USB.

Step 3: open CMD/Terminal

On Windows

Click on ‘Start’ or press the Windows button, type cmd in the search bar, and open the program.

On Mac

Click the Launchpad icon in the Dock, type Terminal in the search field, then click Terminal.

Step 4: Put the roaster into listening mode

Copy and paste the following command into the command prompt:

particle usb start-listening

Hit enter.

Step 5: Give credentials

In the command prompt, write:

particle serial wifi

and insert the SSID and password of the network you want the roaster to connect to.

When asked if you want to scan for nearby Wi-Fi networks, write No.

Your roaster should now be connected to your Wi-Fi.

TROUBLESHOOTING

If you enter the wrong password, the roaster will not connect - try again.
The roaster cannot connect to Wi-Fi without a password.
The roaster can only be connected to password-protected Wi-Fi. Not an open network.
The roaster cannot connect to 5Hz networks.
“ACTIVATE” button is only enabled when the bean drop handle is in an open/upward position.
If the roaster does not respond - restart (switch the roaster off and on).
Corporate networks can create problems. Port 9001 and 1883 must be opened.
Try to use the ROEST Wi-Fi setup app instead if you are unsuccessful with giving your roaster credentials.
