    EMDK, TC25 : How can I trigger the camera view during scanning?

    Erik Van Goubergen



      I am integrating device TC25 in a Xamarin app via EMDK (Visual Studio 2017)

      The scanning of barcodes itself is working, but I have no camera view with the red cross when scanning.

      When I start the DWDemo app and push the scan button, I see immediately the camera view with a red cross. So it must be possible on the TC25 device.


      I was thinking about some missing configuration.

      Here is my code part from InitScanner:


                             //Get the feature object such as BarcodeManager object for accessing the feature.

                              _barcodeManager = (BarcodeManager)_emdkManager.GetInstance(EMDKManager.FEATURE_TYPE.Barcode);


                              _scanner = _barcodeManager.GetDevice(BarcodeManager.DeviceIdentifier.Default);

                              if (_scanner != null)


                                  //Attahch the Data Event handler to get the data callbacks.

                                  _scanner.Data += scanner_Data;

                                  //Attach Scanner Status Event to get the status callbacks.

                                  _scanner.Status += scanner_Status;




                                  //EMDK: Configure the scanner settings

                                  ScannerConfig config = _scanner.GetConfig();

                                  config.SkipOnUnsupported = ScannerConfig.SkipOnUnSupported.None;

                                  config.ScanParams.DecodeLEDFeedback = true;

                                  config.ReaderParams.ReaderSpecific.ImagerSpecific.PickList = ScannerConfig.PickList.Enabled;

                                  config.DecoderParams.Code39.Enabled = true;

                                  config.DecoderParams.Code128.Enabled = false;




      Thanks in advance!
