Does iPad constantly scan for (new) Bluetooth devices (when BT functionality is turned on)? It's that rotating icon in Bluetooth part of the Settings that gives me such impression. Isn't this a bit of an overkill for the battery consumption? Anyway, the whole Bluetooth part of iPad is quite vague -- I suppose it's always scanning and also always displayed to other BT devices. My preferred setup would be to have it "hidden" (as always with BT gadgets so far, at least after you pair those you need to use together), and not constantly scan for new devices when I'm already using it with a keyboard, for instance. Is there any way to achieve this?
