列出并连接到蓝牙设备 [英] List and connect to Bluetooth devices

问题描述

我正在尝试使我的Windows平板电脑应用通过蓝牙与其他设备通信。

I'm tryiing to make my Windows tablet app communicate with an other device via Bluetooth.

首先，我想扫描设备，然后连接到所选的设备。

First I want to scan for devices, then i want to connect to the choosen device.

我我们制作了一个简单的测试应用：空白首页，并在其中添加了一个按钮和一个列表框。然后，我尝试了下面的代码，使我在其他地方不满意：

I've made a simple test app: Blank front page and added a button and a listboxto it. Then I've tried the following code witch I've forund else where here on SO:

    ListBox1.Items.Clear();

    var devices = await DeviceInformation.FindAllAsync(RfcommDeviceService.GetDeviceSelector(RfcommServiceId.SerialPort));

    foreach (var device in devices)
    {
        ListBox1.Items.Add(device);
    }

但列表只是空的

然后，我尝试枚举设备并过滤掉不需要的设备：

Then I've tried to just enum devices and filtered out unwanted devices:

var list = await DeviceInformation.FindAllAsync();
var uniqueList = new HashSet<string>();
var terminators = new List<string>() { "Audio", "Mixer", "Mic", "Realtek", "Usb", "Gmail,", "Line in", "Lyd", "Display", "surface", "@" };

foreach (var element in list)
{

    var strToken = element.Name.ToUpper();

    if (!uniqueList.Add(strToken))
        continue;

    var contains = false;

    foreach (var word in terminators)
        if (strToken.Contains(word.ToUpper()))
            contains = true;


    if (!contains)
        ListBox1.Items.Add(element.Name);
}

但这并没有给出任何详尽的清单。

But that doesn't give any meanfull list.

我感觉自己做错了。请让我回到正轨。

I have a feeling I'm doing ti wrong. Please helt me back on track.

推荐答案

我有一个更明智的选择，我已经解决了另一个这样的问题：

I've just got a little wiser, ive forund an other SO question telling me that it is not posible.

在Windows 8 / 8.1应用商店中搜索并连接到蓝牙设备？

因此，列出的解决方案是：

So the solution for listing is:

1）配对设备

2）列出它们：

ListBox1.Items.Clear();

    var devices = await DeviceInformation.FindAllAsync(RfcommDeviceService.GetDeviceSelector(RfcommServiceId.SerialPort));

    foreach (var device in devices)
    {
        ListBox1.Items.Add(device);
    }
