About Wi-Fi:

This is a troubleshooting guide if you’re having issues connecting to or setting up your Wi-Fi when you receive your machine.

ROEST S100/L100 has a built-in Wi-FI module delivered by Particle. This means that the roaster will automatically connect to an available Wi-Fi to which it has been given the name and password.

There are multiple ways to give these credentials to the roaster, and we recommend using a phone. We have our own app for Android users, and iPhone users can use the Particle app.

Critical info:

The roaster can only be connected to password-protected Wi-Fi. Not an open network.
Wi-Fi name or password cannot include special characters (only letters and numbers).
Corporate networks can create problems. Port 1883 must be opened.

Known issues and possible fixes:

I can’t press the activate button on the Wi-Fi screen.

“ACTIVATE” button is only enabled when the bean drop handle is in an open/upward position.

**The process fails at “claiming the device.”**

This is normal and not a problem. ROEST will be the product’s “owner,“ so we can send OTA updates through Particle.

The machine stops responding during the process of giving the roaster credentials.

Probably a hangup - restart (switch roaster off and on).
If the problem persists – see recovery.

The process fails during the procedure in the Particle or ROEST Wi-Fi setup app.

This can be due to several reasons. Very often it helps to restart the roaster and attempt the process again.
If the problem persists – see recovery.

After completing the procedure for setting up WiFi, the roaster still doesn’t connect.

Make sure the antenna is installed.
If you entered the wrong password, the roaster would not connect - try again.
Restart the roaster and the app to see if this solves the issue. There can be issues with hang-ups.
Enter the WiFi menu and press in the middle of the Debug area. You might need to press several times, but the WiFi you’re trying to connect to must appear here. If the WiFi doesn’t appear, try to relocate the roaster closer to the router. See the below picture:

Set up a mobile hotspot on your phone to help your roaster connect to the server using a set of predefined credentials. See how to do it here.
If the problem persists – see recovery.

I can’t find my Wi-Fi in the ROEST app or Particle app.

Make sure the antenna is installed.
Enter the WiFi menu and press in the middle of the Debug area. You might need to press several times, but the WiFi you’re trying to connect to must appear here. If the WiFi doesn’t appear - try to relocate the roaster closer to the router.
If the problem persists – see recovery.

I’m not able to find the Photon in the Wi-Fi settings of my phone/computer.

Make sure the WiFi setup is activated on the touch screen

Restart the roaster and try again.

If the roaster fails to make a WiFi connection to the app (either with Android or iPhone) then there might be an issue in the WiFi module. The best solution is then to reset the module. This requires a computer with Windows and a USB cord. Use Particle Doctor to reset the module.

If the problem persists – see recovery.

Both the update and Roest server status are offline.

This normally means that the roaster is connected to the Wi-Fi, but doesn’t have internet. This can be caused by firewalls or bad Wi-Fi signal.

Recovery

First, we recommend trying another guide for giving credentials to the roaster. For example, if you have only tried using a phone – then try using a computer with the command prompt instead.
The next step would be to clear all Wi-Fi credentials.
- Take off the top panel. Be careful with the cable connected to the encoder.
- Turn on the roaster and locate the SETUP button on the PCB (see the picture below). Press the button for 10 seconds. It should start blinking blue slowly and then start blinking blue rapidly when finished.
- Once this procedure is done, new Wi-Fi credentials are needed. Follow the procedure for your device to give the roaster new credentials:
If clearing all Wi-Fi credentials and giving the roaster new credentials doesn’t work, see the guide for setting the roaster in safe mode – this can make it easier to connect to Wi-Fi.
The last resort is to use Particle Doctor to reflash the controller.
