ALValue Input Request

This ALValue notifies the needed inputs to succeed in a network connection.

The Input Request is an array of n-pair (key, value).

All the requests contain the key “Network”, the identifier for the network service.

The different keys could be:

  • “Passphrase” for a WEP or WPA/WPA2 passphrase
  • “WPS” for a Wireless Protected Setup enabled Access Point
  • “Name” for the name of a hidden network.
  • “Identity” for a WPA Enterprise Network. Experimental
  • “Username” for a WISPr enabled hotspot. Experimental
  • “Password” for the user password for WPA enterprise or WiSPr Access Point. Experimental
Key Value type Value content
“ServiceId” String The service identifier
“Passphrase” ALValue ALValue Input Details
“WPS” ALValue ALValue Input Details
“Name” ALValue ALValue Input Details
“Identity” ALValue ALValue Input Details
“Password” ALValue ALValue Input Details
“Username” ALValue ALValue Input Details

ALValue Input Details

The Input Details is an array of n-pair (key, value).

A network service may support several authentication methods, in this case it will ask you which method you want to use before requesting further inputs depending on the chosen authentication method. For example most of the recent Access Point support the WPA2 and the WPS as alternative method for the authentication.

The possible keys for the Input Details are:

Key Value type Value content
“Requirement” string

which represents the requirement for the input

Possible values are “Mandatory” or “alternate”
“Alternates” array of string representing the alternatives method.
“Type” string

The type of the requested input.

This can be:

  • “psk” for a WPA/WPA2 passphrase,
  • “wpspin” for a WPS pin code,
  • “string” for a non secret text, or
  • “passphrase” or a WPA Enterprise passphrase.

ALValue Input Reply

The Input Reply is an array of n-pair (key, value).

All the replies to request input must contain the key “ServiceId” with the network service identifier as value.

The Input Reply must also contain all the mandatory fields requested by the event NetworkServiceInputRequired().

Examples:

  • ALValue reply for a WPA/WPA2 Enabled Access Point.

    Key Value content
    “ServiceId” string
    “Passphrase” “Mysecretpassphrase”

  • ALValue reply for a WPA/WPA2 Enabled Access Point with hidden SSID.

    Key Value content
    “ServiceId” string
    “Passphrase” “Mysecretpassphrase”
    “Name” “MyHiddenSSID”

  • ALValue reply for a WPS Enabled Access Point with hidden SSID, using the WPS push button method.

    Key Value content
    “ServiceId” string
    “WPS” “’” (reply an empty string to select push button or give a PIN code to select PIN code method)
    “Name” “MyHiddenSSID”
