Bluetooth does not work. In settings it is set to ON but the visibility option is greyed out. Since install of elementary OS freya from Windows 10, I have not been able to use Bluetooth. My PC is HP 15-r201ne, it has a Realtek card - can't remember the command for getting the exact model.
Maybe this output will help diagnosing the problem,
lsusb; dmesg | grep -i bluetooth; dmesg | grep -i firmware; rfkill list all; lsmod | grep bluetooth; hciconfig -a; uname -a
