New Core Bluetooth Advertisement Keys

Recent Bluetooth Releases have included multiple new keys in the advertisement packets. But there is no documentation about them, and we're left to find them:


* kCBAdvDataLeBluetoothDeviceAddress - MAC Address of LE Device

* kCBAdvDataTimestamp - Timestamp (double value) that can be converted to Date


We found these by looking at the advertising data, but there's no documentation . CBAdvertisementData doesn't include them.

Could you point out to the documentation about the new keys?
