如何在c#中同时使用串口和ble

using System.IO.Ports;
using Windows.Devices.Bluetooth;
using Windows.Devices.Bluetooth.GenericAttributeProfile;

SerialPort serialPort = new SerialPort("COM1", 9600, Parity.None, 8, StopBits.One);

serialPort.Open();

BluetoothLEDevice bleDevice = await BluetoothLEDevice.FromIdAsync(deviceId);

GattDeviceServicesResult servicesResult = await bleDevice.GetGattServicesAsync();
if (servicesResult.Status == GattCommunicationStatus.Success)
{
    foreach (GattDeviceService service in servicesResult.Services)
    {
        GattCharacteristicsResult characteristicsResult = await service.GetCharacteristicsAsync();
        if (characteristicsResult.Status == GattCommunicationStatus.Success)
        {
            foreach (GattCharacteristic characteristic in characteristicsResult.Characteristics)
            {
                // 处理特征
            }
        }
    }
}

// 串口数据读写
serialPort.Write("Hello");
string data = serialPort.ReadExisting();

// BLE数据读写
byte[] writeData = Encoding.UTF8.GetBytes("Hello");
GattCommunicationStatus writeStatus = await characteristic.WriteValueAsync(writeData.AsBuffer());

GattReadResult readResult = await characteristic.ReadValueAsync();
byte[] readData = readResult.Value.ToArray();
string data = Encoding.UTF8.GetString(readData);

serialPort.Close();
bleDevice.Dispose();
