Question

我在Windows桌面应用程序中使用BLE与我的arduino进行通信时遇到了很大的麻烦。我确实理解我必须在我的应用程序中启用WinRT API才能访问GATT并使用win 8.1等（我遵循本教程https://software.intel.com/en-us/articles/using-winrt-apis-from-desktop-applications）。从这一点来说，我不明白如何与我的设备通信。

所以我有这个设备的值（adafruit nrf8001）：

UART服务UUID：6E400001-B5A3-F393-E0A9-E50E24DCCA9E TX特性UUID：6E400002-B5A3-F393-E0A9-E50E24DCCA9E RX特性UUID：6E400003-B5A3-F393-E0A9-E50E24DCCA9E

如何发送一个简单的数组 - 或者更简单的ASCII值到设备？在iOS和Android上我找到了很多例子，但不适用于Windows桌面应用......

如果有人能提供帮助，

会非常高兴！

菲尔编辑：我认为这应该做的工作...但应用程序崩溃的最后一点：

        {
            var Services = await Windows.Devices.Enumeration.DeviceInformation.FindAllAsync(GattDeviceService.GetDeviceSelectorFromUuid(new Guid("6E400001-B5A3-F393-E0A9-E50E24DCCA9E")), null);
            GattDeviceService Service = await GattDeviceService.FromIdAsync(Services[0].Id);

            //Check Service Name
            textBox1.Text = "Using service: " + Services[0].Name;

            GattReliableWriteTransaction gattTransaction = new GattReliableWriteTransaction(); //Orientation on MSDN Article

            GattCharacteristic gattCharacteristic = Service.GetCharacteristics(new Guid("6E400002-B5A3-F393-E0A9-E50E24DCCA9E"))[0];

            //Check Characteristic 
            textBox2.Text = Convert.ToString(gattCharacteristic.CharacteristicProperties);

            //initialize Buffer
            var writer = new Windows.Storage.Streams.DataWriter();
            writer.WriteByte(2);
            gattTransaction.WriteValue(gattCharacteristic, writer.DetachBuffer());


            //Programm Crashes here
            GattCommunicationStatus status = await gattTransaction.CommitAsync();
        }
    }

崩溃：异常：抛出：“无法写入属性。（HRESULT异常：0x80650003）”（System.Exception）抛出System.Exception：“无法写入该属性。（HRESULT异常：0x80650003）”

哇刚刚花了几个小时才得到解决方案：

我只需添加写选项（我也删除了可靠的写入）

    private async void Discover_Click(object sender, EventArgs e)
    {
        var Services = await Windows.Devices.Enumeration.DeviceInformation.FindAllAsync(GattDeviceService.GetDeviceSelectorFromUuid(new Guid("6E400001-B5A3-F393-E0A9-E50E24DCCA9E")));
        GattDeviceService Service = await GattDeviceService.FromIdAsync(Services[0].Id);
        GattCharacteristic gattCharacteristic = Service.GetCharacteristics(new Guid("6E400002-B5A3-F393-E0A9-E50E24DCCA9E"))[0];

        var writer = new DataWriter();
        writer.WriteString("#FF00FF");
        var res = await gattCharacteristic.WriteValueAsync(writer.DetachBuffer(), GattWriteOption.WriteWithoutResponse);
    }

如何在Windows桌面APP中通过蓝牙低功耗发送阵列？
