Connect To Wi-Fi After EMF

There are several ways to connect your Tildagon to Wi-Fi depending on what approach you want to take.

Option 1 - Through the GUI

This is the easiest option, but a real pain to do because you have to type out each letter using the up (A), down (D) and select (B) keys.

1. On the home screen scroll down to settings using the D key, and enter using C key.
2. Scroll through the key to "WIFI SSID" and press enter.
3. Use the up and down keys to select each letter, pressing B to select.
4. Press C to save.
5. Repeat for the "WIFI password" option.
6. If not using WPA2 Enterprise, empty the Enterprise username by editing then submitting without picking any characters.
7. Exit the Settings app using F.
8. Push the Reboop button and try connecting.

Option 2 - Use Tildagon Flasher

Probably the simplest option is to open Tildagon Flasher in a Chromium browser.

1. Open Tildagon Flasher in a Chromium based web browser.
2. With the device connected via USB-C to your computer press "Connect".
3. Select the Tildagon from the list.
4. Select "Logs & Console".
5. Enter the following commands one at a time, followed by enter, editing the 'changeme' sections with your details:

import settings
settings.set('wifi_ssid', 'changeme')
settings.set('wifi_password', 'changeme')

settings.set('wifi_wpa2ent_username', None)

settings.save()

import settings
settings.set('wifi_ssid', 'changeme')
settings.set('wifi_password', 'changeme')
settings.set('wifi_wpa2ent_username', 'username')
settings.save()

6. Push the Reboop button and try connecting.

Option 3 - Use mpremote

1. Install mpremote
2. Connect the Tildagon to your computer using a USB-C data cable
3. On your computer's command line, run mpremote. You should see:

   Connected to MicroPython at /dev/ttyACM0
   Use Ctrl-] or Ctrl-x to exit this shell

4. Hold down the ctrl key on your computer. While holding it down, press the C key on your computer. This will open up a shell for you to enter commands.
5. Enter the following commands one at a time, followed by enter, editing the "changeme" sections with your details:

import settings
settings.set('wifi_ssid', 'changeme')
settings.set('wifi_password', 'changeme')

settings.set('wifi_wpa2ent_username', None)

settings.save()

import settings
settings.set('wifi_ssid', 'changeme')
settings.set('wifi_password', 'changeme')
settings.set('wifi_wpa2ent_username', 'username')
settings.save()

6. Restart the badge. Hold down the ctrl key on your computer. While holding it down, press the D key on your computer.
7. To test if you are connected, open the "App store"

Option 4 - Use mpremote to edit the settings file

1. Install mpremote
2. Connect the Tildagon to your computer using a USB-C data cable
3. On your computer's command line, run mpremote edit settings.json. This should open your default text editor. If it fails with edit: $EDITOR not set then run EDITOR="nano" mpremote edit settings.json to use nano to edit the file.

6. Restart the badge by pressing the reboop button on the device
7. To test if you are connected, open the "App store"

Option 5 - Create a clone of the EMF Wi-Fi network

This could be a good option if you manage a Makerspace or other location where multiple EMF badges might visit.

Because this involves configuring your network this guide can't give detailed instructions.

At a high level you need to:

1. Create a new SSID called "emf2024" that uses WPA2 Enterprise.
2. Create a RADIUS username "badge" and password "badge"
3. Push the Reboop button and try connecting.
