与MultipeerConnectivity Xamarin的连接问题

Question

无法使用MultipeerConnectivity（蓝牙）连接我的设备。

当我从iPhoneA启动我的广告商时，我可以在iPhoneB浏览器上看到iPhoneA。从我的iPhone2（浏览器）发送连接请求后，我在我的iPhoneA上收到请求，但没有连接都没有下降。

如果我在同一设备上试用，我连接到同一设备（iPhone1广告客户和iPhone1浏览器），它可以正常工作并连接。

以下是完整的代码：

using System;
using Foundation;
using MultipeerConnectivity;
using UIKit;

namespace Chat1
{
    public partial class ViewController : UIViewController
    {
        protected ViewController(IntPtr handle) : base(handle)
        {
            // Note: this .ctor should not contain any initialization logic.
        }

        public override void ViewDidLoad()
        {
            base.ViewDidLoad();
            // Perform any additional setup after loading the view, typically from a nib.
            StartMultipeerAdvertiser();
        }

        public override void DidReceiveMemoryWarning()
        {
            base.DidReceiveMemoryWarning();
            // Release any cached data, images, etc that aren't in use.
        }

        partial void BtnBrowse_TouchUpInside(UIButton sender)
        {
            StartMultipeerBrowser();
        }
