What’s the bug number for this issue? I’ll take a look.On Jul 23, 2014, at 11:25 AM, William Henderson < email@hidden> wrote:
This is for an iOS-app-based peripheral, where using the manufacturer’s ID is unfortunately not an option.

Rather than connecting to determine whether or not you want to talk to a given device, could you screen on the manufacturer's ID, in the first two bytes of the advertisement? That should narrow it down a bit.

didDiscoverServices?

On iOS 8 (including the latest iOS beta), I am occasionally seeing an odd behavior where I am seeing services from the OS and/or other apps being discovered in didDiscoverServices in addition to my own app’s UUID. Stranger still, sometimes (usually right after my app has been woken up or relaunched) I temporarily see the other UUID’s but not my own apps. Usually disconnecting and reconnecting (sometimes a couple times) will let me see them all.
This is problematic because (for various reasons I can get into if necessary), I need to call discoverServices on my central with nil – meaning scan for all services. I can’t scan just for my app’s UUID. To work around that, I keep track of peripherals that are advertising things I don’t care about and ‘reject’ them – meaning next time I see their device UUID I don’t bother connecting. But in this case I don’t know whether it’s a bogus device or I just haven’t waited long enough to see my app’s own service UUID. Only work around I’ve found is to attempt connecting/discovering several times before finally rejecting – gross.
