# 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)](https://developer.apple.com/library/ios/documentation/CoreBluetooth/Reference/AppleNotificationCenterServiceSpecification/Introduction/Introduction.html).

This library is mostly a combination of 3 great libraries from [Sandeep Mistry](https://github.com/sandeepmistry):
 * [noble](https://github.com/sandeepmistry/noble) - A Node.js BLE (Bluetooth Low Energy) central module
 * [bleno](https://github.com/sandeepmistry/bleno) - A Node.js module for implementing BLE (Bluetooth Low Energy) peripherals
 * [node-ancs](https://github.com/sandeepmistry/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

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

#### Fedora / Other-RPM based

```sh
sudo yum install bluez bluez-libs bluez-libs-devel
```

#### Running without root/sudo

Run the following command:

```sh
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'`.

```sh
sudo stop bluetooth
```

or

```sh
sudo /etc/init.d/bluetooth stop
```

Usage
-----

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

var ancs = new BleAncs();

__Notification Events__

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

     * businessAndFinance
     * location
     * entertianment
   * categoryCount
   * uid
