[英]Bluetooth 4.0 (low energy) API for windows desktop C# application
[英]How to send array via Bluetooth Low Energy in Windows Desktop APP?
我在Windows桌面應用程序中通過BLE與arduino通信時遇到了很大的麻煩。 我確實知道我必須在應用程序中啟用WinRT API才能訪問GATT並使用Win 8.1等。(我遵循了本教程https://software.intel.com/zh-cn/articles/using-winrt-apis-從桌面應用程序 )。 從現在開始,我不知道如何與我的設備通信。
所以我有該設備的值(adafruit nrf8001):
UART服務UUID:6E400001-B5A3-F393-E0A9-E50E24DCCA9E TX特性UUID:6E400002-B5A3-F393-E0A9-E50E24DCCA9E RX特性UUID:6E400003-B5A3-F393-E0A9-E50E24DCCA9
如何發送簡單的數組-或更簡單的將簡單的ASCII值發送到設備? 在iOS和android上,我可以找到很多示例,但對於Windows桌面應用程序卻找不到。
如果有人可以幫助,我將非常高興!
菲爾編輯:我認為這應該做的工作...但是應用程序在最后一點崩潰了:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using Windows.Devices.Bluetooth.GenericAttributeProfile;
using Windows.Devices.Enumeration;
using Windows.UI.Xaml;
namespace LucidMobileCCproto
{
public partial class LucidMIControlPanel : Form
{
GattDeviceService service2 = null;
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")), 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();
}
}
崩潰:異常:拋出:“無法寫入屬性。(來自HRESULT的異常:0x80650003)”(System.Exception)引發了System.Exception:“無法寫入的屬性。(來自HRESULT的異常:0x80650003)”
哇,我花了幾個小時才得到解決方案:
我只需要添加寫選項(我也刪除了可靠的寫操作)
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);
}
