| EventID(1 Byte) | EventFlags(1 Byte) | CategoryID(1 Byte) | CategoryCount(1 Byte) | NotificationUID(4 Bytes) |
A GATT notification delivered through the Notification Source characteristic contains the following information:
* EventID: This field informs the accessory whether the given iOS notification was added, modified, or removed. The enumerated values for this field are defined
in EventID Values.
* EventFlags: A bitmask whose set bits inform an NC of specificities with the iOS notification. For example, if an iOS notification is considered “important”,
the NC may want to display a more aggressive user interface (UI) to make sure the user is properly alerted. The enumerated bits for this field
are defined in EventFlags.
* CategoryID: A numerical value providing a category in which the iOS notification can be classified. The NP will make a best effort to provide an accurate category
for each iOS notification. The enumerated values for this field are defined in CategoryID Values.
* CategoryCount: The current number of active iOS notifications in the given category. For example, if two unread emails are sitting in a user’s email inbox, and a new
email is pushed to the user’s iOS device, the value of CategoryCount is 3.
* NotificationUID: A 32-bit numerical value that is the unique identifier (UID) for the iOS notification. This value can be used as a handle in commands sent to the
Control Point characteristic to interact with the iOS notification.
