When you do a scan with scanForPeripheralsWithServices, it will normally only notify you once for a particular device address. You can change this to report duplicates by specifying the option CBCentralManagerScanOptionAllowDuplicatesKey. Or you can have your app detect that the other device disconnected using a timeout, and restart your scan.
