There is even a Bluetooth USB adapter here when a device (such as my desktop PC) does not have built-in Bluetooth.
I tested the unit with my phone and it went flawlessly. To connect you can either "Paring Mode" barcode on the supplied list (there are some barcodes are displayed with which you can make various adjustments) scans or holding down for a few seconds to scan button.
Then just look on the receiver unit and connect.
Done.
I then made a few test scans and it worked like a charm!
I must now find a good program with which I can use it (currently I have just tested in Excel and it has the particular barcode abgebildet- as number and the next then the next line).
I'm very satisfied.
The build quality is top, the code is read super fast and the Bluetooth adapter while is was also great!
