WiFiDetectAccessPoint (Function)
In french: WiFiDétectePointAccès
Starts detecting the Wi-Fi access points currently accessible from the device.
Example
NextTitle("Detecting the Wi-Fi access points")
ListPoint is string
sSSID is string
sBSSID is string
ListPoint = WiFiDetectAccessPoint()
FOR EACH STRING AccessPoint OF ListPoint SEPARATED BY CR
sSSID = ExtractString(AccessPoint, 2, TAB)
sBSSID = ExtractString(AccessPoint, 3, TAB)
...
END
Syntax
<Result> = WiFiDetectAccessPoint([<Timeout>])
<Result>: Character string
  • List of detected Wi-Fi access points separated by CR characters (Carriage Return),
  • Empty string ("") if no Wi-Fi access point was detected. The ErrorOccurred variable is used to find out whether an error occurred while detecting the access points. ErrorInfo returns more information on the error.
For each network, a set of information is returned in the following format:
<Identifier> + TAB + <SSID> + TAB + <BSSID> +
TAB + <Security> + TAB + <Signal strength>
where:
  • <Identifier> : Identifier of the network associated with the access point, empty string ("") if the access point corresponds to no network configured on the device.
  • <SSID>: SSID (Service Set Identifier) of the Wi-Fi network associated with the access point.
  • <BSSID>: BSSID (Basic Service Set Identifier) of access point
  • <Security>: Type of security used by the Wi-Fi network:
    wifiSecurityIEEE8021XSecurity that is using the IEEE 802.1x standard.
    wifiSecurityNoneNo security is used.
    wifiSecurityWEPSecurity based on a WEP key (Wired Equivalent Privacy)
    wifiSecurityWPA2Security that is using the WPA2 mechanism (Wi-Fi Protected Access).
    wifiSecurityWPASecurity that is using the WPA mechanism (Wi-Fi Protected Access).
    wifiSecurityWPA_EAPSecurity that is using the WPA mechanism (Wi-Fi Protected Access) and the EAP mechanism (Extensible Authentication Protocol).
  • <Signal strength>: Signal strength expressed in dBm (decibel per milliwatt).
<Timeout>: Optional integer or optional Duration
Maximum duration of detection in hundredths of a second.
  • An error occurs if this timeout is reached before the end of detection.
  • If this timeout is not specified or is set to 0, no time limit will be applied.
This parameter can be:
  • an integer corresponding to the number of hundredths of a second,
  • a Duration variable,
  • the duration in a readable format (e.g., 1 s or 10 ms).
Remarks

Special cases

  • The list of access points returned by WiFiDetectAccessPoint is sorted by order of signal strength (from the strongest signal to the weakest).
  • From Android 6.0: The location must be enabled on the device. Otherwise, the function will return an empty list. GPSStatus is used to find out whether the location is enabled or not.
