advlib-identifier

Library for extracting the wireless device identifier from a transmitted packet. We believe in an open Internet of Things.

Bluetooth Low Energy (BLE)

Extract the identifier (and its type) from a BLE Packet Data Unit (PDU) represented as a hexadecimal string. For example:

const advlib = require('advlib-identifier');
 
let packet = '400dc3dc80ee20e40201060303edfe';
let identifier = advlib.ble.extractIdentifier(packet);
 
console.log(identifier);
// {
//     identifier: "e420ee80dcc3",
//     identifierType: 3
// }

reelyActive (Sub-GHz Active RFID)

Extract the identifier (and its type) from a packet represented as a hexadecimal string. For example:

const advlib = require('advlib-identifier');
 
let packet = '1234567c';
let identifier = advlib.reelyactive.extractIdentifier(packet);
 
console.log(identifier);
// {
//     identifier: "001bc50941234567",
//     identifierType: 1
// }

Identifiers

Identifier types are encoded as numbers. The following identifier types are currently supported.

identifierType	Reference	Description
0	TYPE_UNKNOWN	Unknown identifier
1	TYPE_EUI64	EUI-64
2	TYPE_EUI48	EUI-48 (BLE public address)
3	TYPE_RND48	Random 48-bits (BLE random address)

const advlib = require('advlib-identifier');
 
let identifierType = 3;
 
if(identifierType === advlib.identifiers.TYPE_RND48) {
  console.log('The identifier is a BLE random address');
}
// -> The identifier is a BLE random address
