onConfig Callback

The onConfig callback is called whenever the device receives new parameter values from the UI (usually upon clicking Finish button in captive portal).

You also approve or deny the request by simply returning true or false respectively in the callback.

New values are stored within each NetWizardParameter class and can be accessed using the getValue function for validation/processing etc. Please refer to each parameter type for more details on their API.
