获取蓝牙设备的列表是附近iPhone的SDK [英] Getting list of bluetooth devices nearby on iphone sdk

问题描述

我需要能够到附近搜索所有蓝牙设备，只是那里的ID。我并不需要进行配对的。我使用iPhone 2.3测试版。

I need to be able to search for all bluetooth devices nearby and just get there ids. I don't need to pair at all. I am using iphone 2.3 beta.

这是可能的L使用的GameKit都试过，没有运气没有人知道如何做到这一点。

Is this possible l have tried using GameKit and no luck does anyone know how to do this.

 BOOL result = NO;
if (!session) {
    session = [[GKSession alloc] initWithSessionID:@"SCANNER" 
                                        displayName:nil 
                                        sessionMode:GKSessionModePeer];
    self.session.delegate = self;
    [self.session setDataReceiveHandler:self withContext:nil];
    self.session.available = YES;
    result = YES;
}

它死在[self.session setDataReceiveHandler：自withContext：无];

it dies on [self.session setDataReceiveHandler:self withContext:nil];

与下面的错误

Scanner[42754:207] Error: 30500 -- Invalid parameter for -setDataReceiveHandler:withContext:.

然后
〜DNSServiceRegister回调：REF = 471fa40，旗帜= 2，错误类型= 0 NAME = 00rusor1A..iPhone模拟器regtype = _q1eu29voete9jf._udp。域=本地。

推荐答案

确实自实施所需的方法

- (void) receiveData:(NSData *)data fromPeer:(NSString *)peer inSession: (GKSession *)session context:(void *)context;

地方？否则，它是无法满足 -setDataReceiveHandler的需求：withContext：方法。另外，我不相信你可以在iPhone模拟器中访问蓝牙功能。

somewhere? Otherwise, it is unable to satisfy the needs of the -setDataReceiveHandler:withContext: method. Also, I don't believe you can access Bluetooth functions from within the iPhone Simulator.

总体来说，我不认为这会做你想要什么。的GameKit使用Bonjour发现检测其他的iPhone / iPod touch上运行的本地蓝牙网络中类似的游戏会话。它不会检测到附近的所有蓝牙设备。您可以使用较低级别的Bonjour发现自己找到那些通过WiFi或蓝牙网络访问的卓悦的所有设备，但蓝牙接入本身是从你抽象出来。

Overall, I don't think this will do what you want. GameKit uses Bonjour discovery to detect other iPhones / iPod touches running similar game sessions within a local Bluetooth network. It will not detect all Bluetooth devices in the vicinity. You can use lower-level Bonjour discovery yourself to find all Bonjour devices that are network-accessible via WiFi or Bluetooth, but Bluetooth access itself is abstracted away from you.
