问题描述

任何人对如何使用API​​ ExternalAccessory上Xamarin.iOS线索?

我Xamarin Studio版本是4.0.12(建3),Xamarin.Android版本4.8.1,版本Xamarin.iOS和6.4.5.0 X code是5.0版(5A1413),我试图目标既和6.1 7.0的iPad / iPhone。

我已经走了互联网,并没有太多的文档。即使MonoTouch的文档已经打破链接。

我要的是,列出连接的蓝牙设备,获得再一个名称,然后连接到它,所以我可以打开一个套接字,并开始发送数据给它什么。它是采用串行通信和设备,是的,它拥有苹果外部附件协议ID。

我试过这样:

  VAR AM = EAAccessoryManager.SharedAccessoryManager;

这只是我抛出一个异常的InvaidCastException。

任何线索?

谢谢!我真的AP preciate的帮助。

解决方案

虽然好像你已经工作了这一点,我想我会表现出一定的code段,介绍基本知识(在这种情况下连接到一个SPHERO并把它绿色):

  EAAccessoryManager经理= EAAccessoryManager.SharedAccessoryManager;
VAR配件= mgr.ConnectedAccessories;
的foreach(在附件VAR附件)
{
    myLabel.Text =它让我的附件;
    Console.WriteLine(accessory.ToString());
    Console.WriteLine(accessory.Name);
    VAR协议=com.orbotix.robotprotocol;    如果(accessory.ProtocolStrings.Where(S =&GT氏==协议)。任何())
    {
        myLabel.Text =找了份SPHERO        VAR会话=新EASession(附件,协议);
        VAR的OutputStream = session.OutputStream;
        outputStream.Delegate =新MyOutputStreamDelegate(myLabel);
        outputStream.Schedule(NSRunLoop.CurrentkCFRunLoopDefaultMode);
        outputStream.Open();
    }
}

 公共类MyOutputStreamDelegate:NSStreamDelegate
{
    标签的UILabel;
    布尔hasWritten = FALSE;    公共MyOutputStreamDelegate(标签的UILabel)
    {
        this.label =标签;
    }
    公共覆盖无效的handleEvent(NSStream theStream,NSStreamEvent streamEvent)
    {
        如果(streamEvent == NSStreamEvent.HasSpaceAvailable&放大器;&安培;!hasWritten)
        {
            //设置SPHERO的颜色
            VAR书面=((NSOutputStream)theStream).WRITE(新的byte [] {为0xFF,0xFF的,0X02,为0x20,0x0E的为0x05,0x1F的,为0xFF,0x1B,为0x00,0x91的信息},11);
            如果(书面== 11)
            {
                label.Text =SPHERO应该是绿色的;
            }
            hasWritten = TRUE;
        }
    }
}

Anybody has a clue on how to use the ExternalAccessory API on Xamarin.iOS?

My Xamarin Studio version is 4.0.12(build 3), Xamarin.Android version 4.8.1, Xamarin.iOS version 6.4.5.0 and Xcode is Version 5.0 (5A1413) and I tried target both 6.1 and 7.0 iPad/iPhone.

I've walked the internet and there is not much documentation. Even the MonoTouch docs have broken links.

What I want is, list the connected bluetooth devices, get one of then by name and then connect to it so I can open a socket and start sending data to it. It is a device that uses Serial communication and yes, it has the Apple external accessory protocol ID.

I've tried this:

var am = EAAccessoryManager.SharedAccessoryManager;

It just throws me an exception an InvaidCastException.

Any clues?

Thanks! I really appreciate the help.

解决方案

Although it seems like you've worked this out, I thought I'd show some code snippets that show the basics (in this case connecting to a Sphero and turning it green):

EAAccessoryManager mgr = EAAccessoryManager.SharedAccessoryManager;
var accessories = mgr.ConnectedAccessories;
foreach(var accessory in accessories)
{
    myLabel.Text = "Got me an accessory";
    Console.WriteLine(accessory.ToString());
    Console.WriteLine(accessory.Name);
    var protocol = "com.orbotix.robotprotocol";

    if(accessory.ProtocolStrings.Where(s => s == protocol).Any())
    {
        myLabel.Text = "Got me a Sphero";

        var session = new EASession(accessory, protocol);
        var outputStream = session.OutputStream;
        outputStream.Delegate = new MyOutputStreamDelegate(myLabel);
        outputStream.Schedule(NSRunLoop.Current, "kCFRunLoopDefaultMode");
        outputStream.Open();
    }
}

and

public class MyOutputStreamDelegate : NSStreamDelegate
{
    UILabel label;
    bool hasWritten = false;

    public MyOutputStreamDelegate(UILabel label)
    {
        this.label = label;
    }
    public override void HandleEvent(NSStream theStream, NSStreamEvent streamEvent)
    {
        if(streamEvent == NSStreamEvent.HasSpaceAvailable && ! hasWritten)
        {
            //Set the color of the Sphero
            var written = ((NSOutputStream)theStream).Write(new byte[] {0xFF, 0xFF, 0x02, 0x20, 0x0e, 0x05, 0x1F, 0xFF, 0x1B, 0x00, 0x91}, 11);
            if(written == 11)
            {
                label.Text = "Sphero should be green";
            }
            hasWritten = true;
        }
    }
}
