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 (see nrf_ble_ancs_c_attr_add ).

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

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. nrf_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. nrf_ble_ancs_c_app_attr_request can be used to request attributes of the app that issued the notifications. They arrive in the BLE_ANCS_C_EVT_APP_ATTRIBUTE event. nrf_ancs_perform_notif_action can be used to make the Notification Provider perform an action based on the provided notification.

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.

Function Documentation

uint32_t ancs_c_app_attr_request	(	ble_ancs_c_t *	p_ancs ,
		const uint8_t *	app_id ,
		uint32_t	len
	)

Function for requesting attributes for an app.

Parameters

[in]	p_ancs	iOS notification structure. This structure must be supplied by the application. It identifies the particular client instance to use.
[in]	app_id	App identifier of the app for which to request app attributes.
[in]	len	Length of the app identifier.

Return values

NRF_SUCCESS If all operations were successful. Otherwise, an error code is returned.

void ancs_parse_get_attrs_response	(	ble_ancs_c_t *	p_ancs ,
		const uint8_t *	p_data_src ,
		const uint16_t	hvx_data_len
	)

Function for parsing notification or app attribute response data.

The data that comes from the Notification Provider can be much longer than what would fit in a single GATTC notification. Therefore, this function relies on a state-oriented switch case. UID and command ID will be received only once at the beginning of the first GATTC notification of a new attribute request for a given iOS notification. After this, we can loop several ATTR_ID > LENGTH > DATA > ATTR_ID > LENGTH > DATA until we have received all attributes we wanted as a Notification Consumer. The Notification Provider can also simply stop sending attributes.
