Installation

npm install advlib-ble-gatt

Hello 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.
