The sample app barcodeexmaple is not getting the scanned bar codes.

I'm in the process of develop an app for my client. I have the sdk and compiled the demo app barcodeexample that is with the sdk.

The concierge beeps when a bar code is presented but nothing happens in the app.

I created an profile in the datawedge app and configured the parameters (as the others app configurated in that tool), and no luck.

i´m stuck at this point, what i can check or look at?

Thanks guys.
