WiFiDetectAccessPoint (Function)
In french: WiFiDétectePointAccès
Starts detecting the Wi-Fi access points currently accessible from the device.
AndroidAndroid Widget Remarks:
  • To add the network associated with an access point to the list of networks configured on the device, use WiFiAddNetwork.
  • The Wi-Fi access is not available in the Android emulator.

NextTitle("Detecting the Wi-Fi access points")

ListPoint is string
sSSID is string
sBSSID is string

ListPoint = WiFiDetectAccessPoint()
sSSID = ExtractString(AccessPoint, 2, TAB)
sBSSID = ExtractString(AccessPoint, 3, TAB)
<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 details about the problem.
For each network, a set of information is returned in the following format:
<Identifier> + TAB + <SSID> + TAB + <BSSID> +
TAB + <Security> + TAB + <Signal strength>
  • <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:
    wifiSecurityNoneNo security is used.
    wifiSecurityWEPSecurity based on a WEP key (Wired Equivalent Privacy)
    wifiSecurityWPASecurity that is using the WPA mechanism (Wi-Fi Protected Access).
    wifiSecurityWPA2Security that is using the WPA2 mechanism (Wi-Fi Protected Access).
    wifiSecurityWPA_EAPSecurity that is using the WPA mechanism (Wi-Fi Protected Access) and the EAP mechanism (Extensible Authentication Protocol).
    wifiSecurityIEEE8021XSecurity that is using the IEEE 802.1x standard.
  • <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 correspond to:
  • an integer corresponding to the number of hundredths of a second,
  • a Duration variable,
  • Versions 23 and later
    the direct indication of duration (1 s or 10 ms for example).
    New in version 23
    the direct indication of duration (1 s or 10 ms for example).
    the direct indication of duration (1 s or 10 ms for example).

Special cases

  • The list of access points returned by WiFiDetectAccessPoint is sorted by order of signal strength (from the strongest signal to the weakest).
  • AndroidAndroid Widget If the function is run by the main thread of the application, an hourglass (infinite progress bar) will be displayed during the detection of access points. To specify the message that will be displayed in the hourglass, use NextTitle just before the call to WiFiDetectAccessPoint.
  • 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.
