Controller WiFi
This applies to both the wallaby and wombat controllers.
One way to connect directly to a controller is through a WiFi network.
To access the web interface, enter 192.168.125.1:8888 in the browser after connecting.
The controller's wifi network is initialized after boot through /home/pi/wifi_configurator.py
By default, the network name (SSID) is in this format: <wallaby_id>-<'wallaby'|'wombat'>
Examples:1904-wallaby 2211-wombat
The default password can be found in Settings > Network.
It's generated by computing the SHA256 hash of the controller id; then the first 6 characters of the hashsum followed by 00.
Often this password is changed from default for security reasons.
In /home/pi/wifi_configurator.py, locate the line starting with wpa_passphrase
Chose a password, and then set the variable to wpa_passphrase=<yourpassword>\n.
The network name can be changed in a similar fashion:
In wifi_configurator.py, locate the line starting with ssid
Append your changes after ssid= and end with a \n newline.
