Note, that due the way in which Bluetooth device discovery works, the existence and address of a device is known first, but a separate query has to be carried out to find whether the device also has a name. This means that if a device is discovered afresh then this property might return only a text version of the device’s address and not its name, one can also see this in the Windows’ Bluetooth device dialogs where the device appears first with its address and the name is later updated. To see the name, wait for some time and access this property again having called Refresh()()() in the meantime.
