How to disconnect/stop scanning of Socket Mobile scanner using API?

Question

In my app Socket Mobile Scanner is integrated to scan inventory items, my requirement is to stop scanner's scanning until the app search/check items existence.

If the recent items is not valid item, Scanner should stop scanning.

I used below code :

/// here scanApiHelper is instance of ScanApiHelper 
scanApiHelper?.pop(self)
scanApiHelper?.close()

there is a data confirmation mode that you can use which will cover this scenario. In this mode, the trigger is lock for a certain time unless you explicitly acknowledge the data from the app. The trigger lockout time can be configured. The other possibility is to disable the trigger temporally and re-enable it when your app is ready.

Have a look at the github singleentry-ios (https://github.com/SocketMobile/singleentryswift-ios) it has a code example of Data Confirmation :

    func onDecodedDataResult(_ result: Int, device: DeviceInfo!, decodedData: ISktScanDecodedData!) {
    print("onDecodedDataResult in the detail view")
    if result==ESKT_NOERROR {
        let rawData = decodedData.getData()
        let rawDataSize = decodedData.getSize()
        let data = Data(bytes: UnsafePointer<UInt8>(rawData!), count: Int(rawDataSize))
        print("Size: \(rawDataSize)")
        print("data: \(data)")
        let str = NSString(data: data, encoding: String.Encoding.utf8.rawValue)
        let string = str as! String
        print("Decoded Data \(string)")
        self.decodedData.text = string
        // this code can be removed if the application is not interested by
        // the host Acknowledgment for the decoded data
        #if HOST_ACKNOWLEDGMENT
            ScanApiHelper.shared().postSetDataConfirmationOkDevice(device, target: self, response: #selector(onSetDataConfirmation(_:)))
        #endif
    }
}

#if HOST_ACKNOWLEDGMENT
func onSetDataConfirmation(_ scanObj: ISktScanObject){
    let result = scanObj.msg().result()
    if result != ESKT_NOERROR {
        print("error trying to confirm the decoded data: \(result)")
    }
}
#endif

The scanner needs to be configured once to this mode:

    #if HOST_ACKNOWLEDGMENT
        scanApiHelper?.postGetLocalAcknowledgmentDevice(deviceInfo, target: self, response: #selector(onGetLocalAcknowledgment(_:)))
        scanApiHelper?.postGetDecodeActionDevice(deviceInfo, target: self, response: #selector(onGetDecodeAction(_:)))
    #else // to remove the Host Acknowledgment if it was set before
        scanApiHelper?.postGetLocalAcknowledgmentDevice(deviceInfo, target: self, response: #selector(onGetLocalAcknowledgmentLocalAck(_:)))
        scanApiHelper?.postGetDecodeActionDevice(deviceInfo, target: self, response: #selector(onGetDecodeActionLocalAck(_:)))
    #endif

I hope this helps.
