Objective

This example demonstrates the Apple Notification Center Service (ANCS) functionality using the PSoC 4 BLE family of

generated on the iOS device. This can be used to quickly design an accessory such as a smartwatch, which can pair with an

iPhone.

This example showcases how PSoC 4 BLE can be used to support ANCS. The BLE Pioneer Kit is connected to an iPhone

and a UART based console informs the user of the ongoing activity on the iPhone.

Incoming calls (with the caller name) are displayed on the terminal and can be accepted or declined by the user directly from

the terminal. The number of missed calls, voicemails and emails is also shown.

For more information on ANCS itself, refer to the Apple Notification Center Service specification.

Project Description

This project implements a GATT Client and GAP Peripheral role. Being a Peripheral, the device advertises and waits for the

iOS device to initiate a connection. Once connected, the device requests authentication, for which a passkey is displayed on

emails, as per the iOS device.

For an incoming call notification, the kit writes to the Control Point characteristic to request for the Attribute ID Title. This

results in a GATT notification on the Data Source characteristic, from which the kit extracts the caller information. An alert is

shown on the UART output, along with this caller information. The user is asked to Accept or Decline this incoming call. If the

user enters ‘Y’ this call is accepted. If the user enters ‘N’ this call is declined.

Bonding is implemented in this project, i.e. the encryption keys are stored to non-volatile memory (flash). This implies that a

passkey exchange is required only once with the iOS device. The bonding information can be removed at any time by pressing

‘R’ on the terminal. Note that Bonding is called Pairing on iOS devices. If the bonding information is removed on the kit, the

device should be unpaired on the iOS side as well, and vice-versa.
