== Compile error when integrate in my project ==
I am working on a Angular project. I created a component and insert the code bluetooth sample into the component ts file. The ts code is:

`import { Component, OnInit } from '@angular/core';

@Component({
  selector: 'app-bluetooth',
  templateUrl: './bluetooth.component.html',
  styleUrls: ['./bluetooth.component.css']
})
export class BluetoothComponent implements OnInit {

  constructor() {
  }

  ngOnInit() {
  }

  log() {
    var line = Array.prototype.slice.call(arguments).map(function(argument) {
      return typeof argument === 'string' ? argument : JSON.stringify(argument);
    }).join(' ');
    document.querySelector('#log').textContent += line + '\n';
  }

  clearLog() {
    document.querySelector('#log').textContent = '';
  }

  setStatus(status) {
    document.querySelector('#status').textContent = status;
  }

  setContent(newContent) {
    var content = document.querySelector('#content');
    while(content.hasChildNodes()) {
      content.removeChild(content.lastChild);
    }
    content.appendChild(newContent);
  }

  onButtonClick() {
    this.clearLog();
    this.log('Requesting any Bluetooth Device...');
    navigator.bluetooth.requestDevice({
     // filters: [...] <- Prefer filters to save energy & show relevant devices.
        acceptAllDevices: true,
        optionalServices: ['device_information']})
    .then(device => {
      this.log('Connecting to GATT Server...');
      return device.gatt.connect();
    })
    .then(server => {
      this.log('Getting Device Information Service...');
      return server.getPrimaryService('device_information');
    })
    .then(service => {
      this.log('Getting Device Information Characteristics...');
      return service.getCharacteristics();
    })
    .then(characteristics => {
      let queue = Promise.resolve();
      let decoder = new TextDecoder('utf-8');
      characteristics.forEach(characteristic => {
        switch (characteristic.uuid) {

          case BluetoothUUID.getCharacteristic('manufacturer_name_string'):
            queue = queue.then(_ => characteristic.readValue()).then(value => {

            queue = queue.then(_ => characteristic.readValue()).then(value => {
              this.log('> Hardware Revision String: ' + decoder.decode(value));
            });
            break;

          case BluetoothUUID.getCharacteristic('firmware_revision_string'):
            queue = queue.then(_ => characteristic.readValue()).then(value => {

    .catch(error => {

  }

  /* Utils */

  padHex(value) {
    return ('00' + value.toString(16).toUpperCase()).slice(-2);
  }

  getUsbVendorName(value) {
    // Check out page source to see what valueToUsbVendorName object is.
    return value +
        (value in valueToUsbVendorName ? ' (' + valueToUsbVendorName[value] + ')' : '');
  }
}
`

However I got below compile errors. Seems I 

ERROR in src/app/bluetooth/bluetooth.component.ts(41,5): error TS2554: Expected 0 arguments, but got 1.
