Can't connect PC with redbearlab shield v2.1 arduino mega


We have a redbearlab shield v2.1 which we want to connect to a pc via USB BLE adapter. In the arduino plate we have installed the BLEControllerSketch.ino and we have installed the libraries rbl_nrf8001 and BLE_SDK_for arduino.
The usb software detects the device, but does not link or connect … you think we can do or are doing wrong
Thank you
