Answer 1

In CoreBluetooth all management is done by application layer. In your case, what I would do it is to listen for disconnect event than in same event, reconnect the peripheral. The connection method is an inexpensive one and assure you to reconnect to your device when it is back in range.

Note that if you explicitly disconnect the device, you received the same disconnect event, but you haven't to call the reconnect method.
