You can test it by going to settings => general => reset => reset alle settings, or simply change the BdAddr of the device. You will run into bugs almost certainly if you don't have defensive code at all places where you create a string from the CFUUIDRef ;-) On Fri, Aug 24, 2012 at 1:12 AM, Glenn Maynard <glenn@bluegoji.com> wrote:

Please note that the lack of UUID does not prevent you from doing what I think you want to do (if that's not the case, then please explain to me what you are trying to do). In your app you can still check if it is the same CBPeripheral object that is being reported over and over again. Since the peripheral should use a random resolvable address that changes at least ever 15 minutes, the address will change and the device will appear to be a "new" device. The only way to long term be able to track device is to connect and pair with it. That way we will get the IRK to resolve the address and present that to you as a UUID.
Is this documented anywhere? I currently have a pairing UI that stores the UUID received from didDiscoverPeripheral when the user says to pair to a device, then we connect to that UUID from then on (through retrievePeripherals). This has worked consistently in my testing, but from the above it sounds like this may not always work, and it's troubling that the first I've heard of this is a random mailing list post (and it sounds like it's not just me).
