  filters: [{services: ['heart_rate']}]
});
let gatt = await device.gatt.connect();
let service = await gatt.getPrimaryService('heart_rate');
let characteristic = await service.getCharacteristic('heart_rate_measurement');
if (characteristic.properties.notify) {
  characteristics.addEventListener('characteristicvaluechanged',
      function(event) {
    console.log(`Received heart rate measurement: ${event.target.value}`);
  }
  await characteristic.startNotifications();
