C# 用Windows11 API实现 HID蓝牙的链接通信

好的，下面是一个简单的示例代码，可以使用 Windows 11 API 实现 HID 蓝牙的连接和通信：

using System;
using System.Runtime.InteropServices;
using System.Threading.Tasks;
using Windows.Devices.Bluetooth;
using Windows.Devices.Bluetooth.GenericAttributeProfile;

namespace BluetoothHidDemo
{
    class Program
    {
        private static GattDeviceService _hidService;
        private static GattCharacteristic _inputReport;
        private static GattCharacteristic _outputReport;

        static async Task Main(string[] args)
        {
            // 找到 HID Service
            var devices = await DeviceInformation.FindAllAsync(GattDeviceService.GetDeviceSelectorFromUuid(GattServiceUuids.HumanInterfaceDevice));
            if (devices.Count == 0)
            {
                Console.WriteLine("未找到 HID Service 设备");
                return;
            }

            var device = await BluetoothLEDevice.FromIdAsync(devices[0].Id);
            _hidService = device.GetGattService(GattServiceUuids.HumanInterfaceDevice);

            // 找到 Input Report 和 Output Report 特征
            var characteristics = _hidService.GetAllCharacteristics();
            foreach (var characteristic in characteristics)
            {
                var props = characteristic.CharacteristicProperties;
                if (props.HasFlag(GattCharacteristicProperties.Read))
                {
                    _inputReport = characteristic;
                }
                if (props.HasFlag(GattCharacteristicProperties.Write))
                {
                    _outputReport = characteristic;
                }
            }

            // 订阅 Input Report 特征的通知
            var status = await _inputReport.WriteClientCharacteristicConfigurationDescriptorAsync(GattClientCharacteristicConfigurationDescriptorValue.Notify);
            if (status == GattCommunicationStatus.Success)
            {
                _inputReport.ValueChanged += InputReport_ValueChanged;
            }

            // 发送 Output Report
            var buffer = new byte[] { 0x01, 0x02, 0x03 };
            var writeResult = await _outputReport.WriteValueAsync(buffer.AsBuffer());
            if (writeResult.Status == GattCommunicationStatus.Success)
            {
                Console.WriteLine("发送成功");
            }
            else
            {
                Console.WriteLine($"发送失败，错误代码：{writeResult.ProtocolError}");
            }

            Console.ReadLine();
        }

        private static void InputReport_ValueChanged(GattCharacteristic sender, GattValueChangedEventArgs args)
        {
            var buffer = args.CharacteristicValue;
            var data = new byte[buffer.Length];
            Marshal.Copy(buffer.Data, data, 0, buffer.Length);

            Console.WriteLine($"收到数据：{BitConverter.ToString(data)}");
        }
    }
}

需要注意的是，该代码仅供参考，具体的实现还需要根据具体的 HID 设备和蓝牙模块进行调整。
