I have a BT enabled wifi card installed, it works fine with the BT keyboard that I've tried and the BT serial adapter. I just bought a Lenovo N700 wireless mouse that also has a bluetooth mode. I have a feeling that the BT mode is a Windows only thing because it does absolutely nothing after I pair it to the Cent 7 computer. If I use the included wireless USB dongle it works fine. Thing is I need the single USB port that I have on this machine for something else, which is why I bought one that had a BT mode.
What makes me ask for help is that when I'm pairing it, it shows as an unknown device type and I'm hoping someone can help me change that device type to a mouse after I have it paired.
