advlib-ble
==========
Wireless advertising packet decoding library for Bluetooth Low Energy. __advlib-ble__ can be used standalone or, more commonly, as a processor module of the protocol-agnostic [advlib](https://github.com/reelyactive/advlib) library.
__advlib-ble__ is a lightweight [Node.js package](https://www.npmjs.com/package/advlib-ble) that implements the Core Bluetooth Specification and can be extended with libraries to decode service data and manufacturer-specific data outside of this specification.
| Library | Decodes |
|:--------|:--------|
| [advlib-ble-services](https://github.com/reelyactive/advlib-ble-services) | Service Data |
| [advlib-ble-manufacturers](https://github.com/reelyactive/advlib-ble-manufacturers) | Manufacturer-Specific Data |
| [advlib-ble-gatt](https://github.com/reelyactive/advlib-ble-gatt) | GATT Protocol-Specific Data |
Installation
------------
npm install advlib-ble
Hello advlib-ble!
-----------------
```javascript
const advlib = require('advlib-ble');
const LIBRARIES = [ require('advlib-ble-services'),
require('advlib-ble-manufacturers'),
require('advlib-ble-gatt' ];
let packet = 'c21d04acbe55daba16096164766c6962206279207265656c79416374697665';
let processedPacket = advlib.process(packet, LIBRARIES);
console.log(processedPacket);
```
Which should yield the following console output:
{ rxAdd: "random",
txAdd: "random",
type: "ADV_NONCONN_IND",
length: 29,
advA: "bada55beac04",
name: "advlib by reelyActive" }
Options
-------
__advlib-ble__ supports the following options for its process function:
| Property | Default | Description |
|:-----------------------|:--------|:------------------------------------|
| ignoreProtocolOverhead | false | Ignore BLE-specific properties (txAdd, length, type, advA, etc.) |
| isPayloadOnly | false | Interpret data as the optional PDU payload only (i.e. without header or advertiser address) |
| indices | [] | URI-lookup indices such as Sniffypedia |
For example, to ignore the Bluetooth Low Energy protocol overhead:
```javascript
let packet = 'c21d04acbe55daba16096164766c6962206279207265656c79416374697665';
let options = { ignoreProtocolOverhead: true };
let processedPacket = advlib.process(packet, [], options);
```
Which should yield the following console output:
{ name: "advlib by reelyActive" }
If only the payload is available, the example above would be handled as follows:
```javascript
let payload = '16096164766c6962206279207265656c79416374697665';
let options = { isPayloadOnly: true };
let processedPayload = advlib.process(packet, [], options);
```
Which should again yield the following console output:
{ name: "advlib by reelyActive" }
For example, to append implicit URIs using the Sniffypedia index:
```javascript
let packet = '401490a3a947507b02011a0aff4c0010050a10b4f1e2';
let options = { indices: [ require('sniffypedia') ] };
let processedPacket = advlib.process(packet, [], options);
```
Which should yield the following console output:
{ uri: "https://sniffypedia.org/Organization/Apple_Inc/" }
