node.js TI SensorTag humidity sensor example.

humidity.js

var SensorTag = require('sensortag');

SensorTag.discover(function(sensorTag) {
  console.log('discover');
  sensorTag.connect(function() {
    console.log('connect');
    sensorTag.discoverServices(function() {
      console.log('discoverServices');
      sensorTag.discoverCharacteristics(function() {
        console.log('discoverCharacteristics');
        sensorTag.enableHumidity(function() {
          sensorTag.on('humidityChange', function(temperature, humidity) {
            console.log('\ttemperature = %d °C', temperature.toFixed(1));
            console.log('\thumidity = %d %', humidity.toFixed(1));
          });

          sensorTag.notifyHumidity(function() {
            console.log('notifyHumidity');
          });
        });
      });
    });
  });
});

using bluez 5.19 on arch linux raspberry pi, running as root.
Code blows up at line 5 since sensorTag is a uuid, not a peripheral.
