我如何知道 Windows phone 8 上是否启用了蓝牙? [英] How can I know bluetooth is enabled or not on Windows phone 8?

问题描述

我可以使用ConnectionSettingsTask访问蓝牙设置，但是任务完成后如何知道蓝牙是否开启?

I can use ConnectionSettingsTask to access Bluetooth settings, but how can I know whether Bluetooth's enabled after the task is completed?

我查看了 windows phone 市场，发现有些应用程序可以做到这一点，例如:

I checked windows phone marketplace, found that some app can do that, for example:

It's just a suggestion,this is what i am using, i am sure that there are better ways

 private async void FindPaired()
    {
        Windows.Networking.Proximity.PeerFinder.Start();
        try
        {
            var peers = await Windows.Networking.Proximity.PeerFinder.FindAllPeersAsync();
            bth = true; //boolean variable
        }
        catch (Exception ex)
        {
            if ((uint)ex.HResult == 0x8007048F)
            {
                bth = false;
            }
           
        }          
    }
