Detailed Description

Apple Notification Center Service Client Module.

Disclaimer: This client implementation of the Apple Notification Center Service can be changed at any time by Nordic Semiconductor ASA. Server implementations such as the ones found in iOS can be changed at any time by Apple and may cause this client implementation to stop working.

This module implements the Apple Notification Center Service (ANCS) client. This client can be used as a Notification Consumer (NC) that receives data notifications from a Notification Provider (NP). The NP is typically an iOS device acting as a server. For terminology and up-to-date specs, see http://developer.apple.com .

The term "notification" is used in two different meanings:

An iOS notification is the data received from the Notification Provider.
A GATTC notification is a way to transfer data with Bluetooth Smart. In this module, we receive iOS notifications using GATTC notifications. We use the full term (iOS notification or GATTC notification) where required to avoid confusion.

Upon initializing the module, you must add the different iOS notification attributes you would like to receive for iOS notifications. ble_ancs_c_attr_add .

Once a connection is established with a central device, the module does a service discovery to discover the ANVS server handles. If this succeeds ( BLE_ANCS_C_EVT_DISCOVERY_COMPLETE ) The handles for the CTS server are part of the ble_ancs_c_evt_t structure and must be assigned to a ANCS_C instance using the ble_ancs_c_handles_assign function. For more information about service discovery, see the ble_discovery module documentation Database Discovery Module .

The application can now subscribe to iOS notifications using ble_ancs_c_notif_source_notif_enable . They arrive in the BLE_ANCS_C_EVT_NOTIF event. ble_ancs_c_request_attrs can be used to request attributes for the notifications. They arrive in the BLE_ANCS_C_EVT_NOTIF_ATTRIBUTE event.

Note: The application must propagate BLE stack events to this module by calling ble_ancs_c_on_ble_evt() from the SoftDevice Event Handler callback.
