BeaconDetectPrecise (Function) Used to find the Beacons near the device. // In a museum, we want to display on the visitor device the information
// regarding the masterpiece he is looking at. Associate to each Beacon
// the same UUID corresponding to the museum as well as Major and Minor numbers
// allowing each Beacon to be uniquely identified.
// A Beacon is placed next to each work of art in the museum.
// The application must call the BeaconDetectPrecise function with a
// BeaconGroup variable corresponding to the museum tags.
// The callback procedure passed as parameter to the function will be called whenever
// a new list of Beacons is detected. Then, all you have to do is find
// the nearest Beacon to identify the work the visitor is looking at and to display
// the corresponding information in the application.
// Museum UUID
sUUID is string = "f4231ab6-5ef2-6c99-4229-af6c72e0446e"
// Create a beaconGroup variable corresponding to the museum tags
groupMuseum is beaconGroup
groupMuseum.UUID = sUUID
// Start the detection
BeaconDetectPrecise(groupMuseum, ProcDetection)
INTERNAL PROCEDURE ProcDetection(arrInfo is array of beaconDetectionInfo)
nMinDistance is int
NearestBeacon is beaconDetectionInfo
FOR EACH Information OF arrInfo
IF nMinDistance = 0 _OR_ Information.Distance < nMinDistance
NearestBeacon = Information
END
END
// Display information about the masterpiece associated with the tag
DisplayMasterpieceInfo(NearestBeacon.Major, NearestBeacon.Minor)
END
Sintaxis
<Result> = BeaconDetectPrecise(<Group of Beacons> , <WLanguage procedure>)
<Result>: Boolean - True if the detection was started,
- False otherwise. To get more details on the error, use ErrorInfo.
<Group of Beacons>: beaconGroup variable Name the of beaconGroup variable that describes the searched group of Beacons. <WLanguage procedure>: Procedure name Name of the WLanguage procedure ("callback") called when a new list of Beacons is detected. This procedure has the following format: PROCEDURE <Procedure Name>(<Array of Detection Info>) where <Array of detection info> is a beaconDetectionInfo variable that describes the information about the detected Beacons (identifiers, Major/Minor numbers, distance, etc.) Componente: wd300android.aar |
