How to integrate Bluetooth Scanner into Xamarin App on Non-Zebra Device

I'm one step further. I did set an explicit Target Framework and now the instantiation of SDKHandler works.

Now I tried to get the SdkVersion: _sdkhandler.DcssdkGetVersion();returns an empty string.

The I tried to get a list of available and/or connected scanners (there was a DS3678 connected at the time). The list is empty so I'm obviously missing something here.

Here's my code:

                _sdkhandler = new SDKHandler(Context);

                List<DCSScannerInfo> scannerinfos = new List<DCSScannerInfo>();

                scannerinfos.Clear();

                string version = _sdkhandler.DcssdkGetVersion();  <== returns an empty string

                _sdkhandler.DcssdkGetAvailableScannersList(scannerinfos); <== returns an empty list

                _sdkhandler.DcssdkGetActiveScannersList(scannerinfos);  <== returns an empty list

Any help would be grately appreciated

Best regards
