蓝牙LE扫描仪Xamarin Android

Question

我想用我的应用程序做的是能够读取扫描设备的特性。我能够扫描设备，但扫描将继续捕获它发现的任何内容。所以我想有一个过滤器。我的结果的附图位于我的代码下方。

这是我的代码

using Robotics.Mobile.Core.Bluetooth.LE;
using Adapter = Robotics.Mobile.Core.Bluetooth.LE.Adapter;

var appContext = Application.Context;
            _manager = (BluetoothManager)appContext.GetSystemService(BluetoothService); // ("bluetooth");
            _adapter = _manager.Adapter;

            _bleAdapter = new Adapter();
            _bleAdapter.DeviceDiscovered += _bleAdapter_DeviceDiscovered;
            _bleAdapter.ScanTimeoutElapsed += _bleAdapter_ScanTimeoutElapsed;
        }

        private void _bleAdapter_ScanTimeoutElapsed(object sender, EventArgs e)
        {
            _bleAdapter.StopScanningForDevices();
            DisplayInformation("Bluetooth scan timeout elapsed, no ble devices were found");
        }

        private void _bleAdapter_DeviceDiscovered(object sender, DeviceDiscoveredEventArgs e)
        {
            var msg = string.Format(@"Device found: {0}
  {1} - {2}", e.Device.Name, e.Device.ID, e.Device.Rssi);
            DisplayInformation(msg);
        }

        private void ButtonScanBleClick(object sender, EventArgs e)
        {
            if (!_bleAdapter.IsScanning)
                _bleAdapter.StartScanningForDevices();
        }

        private void DisplayInformation(string line)
        {
            _textboxResults.Text = $"{line}\r\n{_textboxResults.Text}";
            Console.WriteLine(line);
        }
