bar code scanner with apps

I have a unitech MS910 bar code scanner. using the keyboard wedge BluetoothConnect that came with the scanner. It works fine but scans only populate the input field, then I have to use the apps software enter button to submit the scanned code. Can not figure how to enter the information during scan. Is it the app, or does the scanner populate and enter code?

ecmobile is the app.

 

found it, have to add suffix (post amble) to enter in the scanner.
