ESP-IDF BLE ANCS Example
==========================
The purpose of the Apple Notification Center Service (ANCS) is to give Bluetooth accessories (that connect to iOS devices through a Bluetooth low-energy link) a simple and convenient way to access many kinds of notifications that are generated on iOS devices.
The Apple Notification Center Service is a primary service whose service UUID is 7905F431-B5CE-4E99-A40F-4B1E122D00D0.
Only one instance of the ANCS may be present on an NP. Due to the nature of iOS, the ANCS is not guaranteed to always be present. As a result, the NC should look for and subscribe to the Service Changed characteristic of the GATT service in order to monitor for the potential publishing and unpublishing of the ANCS at any time.
In its basic form, the ANCS exposes three characteristics:
Notification Source: UUID 9FBF120D-6301-42D9-8C58-25E699A21DBD (notifiable)
Control Point: UUID 69D1D8F3-45E1-49A8-9821-9BBDFDAAD9D9 (writeable with response)
Data Source: UUID 22EAC6E9-24D6-4BB5-BE44-B36ACE7C7BFB (notifiable)
All these characteristics require authorization for access.

| 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.
