Groove BLE connection to PC


I have Groove BLE with Arduino Uno (using SoftwareSerial lib, pins 6 and 7) and I want to communicate (serial) with PC, where I have USB bluetooth dongle. The problem is that PC don’t see the groove BLE when trying to add a device.

So what I need to do to make the connection?
Is the there sample or instructions to this somewhere?
Is the problem that the PC dongle is bluetooth V2.0?
Is the problem that BLE is not in SPP mode, if so how to set SPP mode? I understood one can set BLE to this mode, but how?
