BLE ANCS

===========

This is a NodeJS library that provides Linux systems with notifications from iOS devices via Bluetooth LE, using the Apple Notification Center Service (ANCS).

This library is mostly a combination of 3 great libraries from Sandeep Mistry:

noble - A Node.js BLE (Bluetooth Low Energy) central module
bleno - A Node.js module for implementing BLE (Bluetooth Low Energy) peripherals
node-ancs - A node.js lib to access the Apple Notification Center Service (ANCS)

I have combined noble and bleno together so it is possible to easily pivot from being a peripheral to a central role. This allows for a Pairing to be established between the iOS device and the Linux system without any requiring any iOS Apps. You can simply go into the Bluetooth setting and connect with the Linux system to establish an ANCS pairing.

Prerequisites

Linux (Ubuntu)

Kernel version 3.6 or above
libbluetooth-dev

Ubuntu/Debian/Raspbian

sudo apt-get install bluetooth bluez libbluetooth-dev libudev-dev

Fedora / Other-RPM based

sudo yum install bluez bluez-libs bluez-libs-devel

Running without root/sudo

Run the following command:

sudo setcap cap_net_raw+eip $(eval readlink -f `which node`)

This grants the node binary cap_net_raw privileges, so it can start/stop BLE advertising.

Note: The above command requires setcap to be installed, it can be installed using the following:

apt: sudo apt-get install libcap2-bin
yum: su -c \'yum install libcap2-bin\'

IMPORTANT!

You need to have the Bluetooth Service / bluetoothd initially running while the bluetooth LE dongle is attached. After they have initialized the dongle, stop the bluetooth service from running. Watch out for it respawning. Do a quick check with ps -A | grep 'blue'.

sudo stop bluetooth

sudo /etc/init.d/bluetooth stop

Usage

var BleAncs = require('ble-ancs');

var ancs = new BleAncs();

Notification Events

ancs.on('notification', function(notification) {
    ...
});

notification has the following properties
- event (one of):
  - added
  - modified
  - removed
- flags (array):
  - silent
  - important
- category (one of):
  - other

  - email
  - other
  - news
  - healthAndFitness
  - businessAndFinance
  - location
  - entertianment
- categoryCount
- uid

Operations for 'added' or 'modified' notifications (event property)

Read App Identifier

notification.readAppIdentifier(function(appIdentifier) {
  ...
});

Read Title

notification.readTitle(function(title) {
  ...
});

Read Subtitle

notification.readSubtitle(function(subtitle) {
  ...
});

Read Message

notification.readMessage(function(message) {
  ...
});

Read Date

notification.readDate(function(date) {
  ...
});

Read All Attributes

notification.readAttributes(function(attributes) {
  ...
});

attributes has the following properties
- appIdentifier
- title
- subtitle
- message
- date
