Wireless packet decoding library for Bluetooth Low Energy GATT data. advlib-ble-gatt is typically used as a library for advlib-ble which itself is commonly a processor module of the protocol-agnostic advlib.
advlib-ble-gatt is a lightweight Node.js package with no dependencies.
npm install advlib-ble-gatt
const advlib = require('advlib-ble-gatt');
let protocolSpecificData = {
gatt: [ { serviceUuid: "1c930003d45911e79296b8e856369374",
characteristicUuid: "1c930038d45911e79296b8e856369374",
value: "480d" },
{ serviceUuid: "1c930003d45911e79296b8e856369374",
characteristicUuid: "1c930032d45911e79296b8e856369374",
value: "c019" } ]
};
let processedData = advlib.processProtocolSpecificData(protocolSpecificData);
console.log(processedData);Which should yield the following console output:
{ batteryVoltage: 3.4, temperature: 25.75 }
The advlib-ble-gatt library observes these standard properties.
The following services, in order of their UUID, are supported by advlib-ble-gatt.
| Service UUID(s) | /lib file |
