一、服务端（也叫周边设备吧。。脑残的翻译）
1.实现类必须遵守协议&CBPeripheralManagerDelegate
2.需要的主要类有：
@property(strong,nonatomic) CBPeripheralManager *peripheraM
@property(strong,nonatomic) CBMutableCharacteristic *customerC
&@property (strong,nonatomic) CBMutableService *customerS
3.调用流程代码中有注释

iOS蓝牙不立即断开问题请教&&&
有熟悉iOS蓝牙的大神吗,请教一下蓝牙断开的问题,执行[centralManager cancelPeripheralConnection:self.peripheral];这个方法后,回调有提示蓝牙已断开,但实际手机蓝牙还处在连接的状态,蓝牙小图标还是亮着的.等了5秒左右才变成灰色,真正断开了蓝牙[ 此帖被zhangming-07-27 16:47重新编辑 ]

如果已经连接时间超过8秒左右,你再执行断开的方法,它会立即断开,如果刚刚连接上才2-3秒,就回调取消连接,则iPhone上的蓝牙标志还是高亮连接状态,要过几秒才会暗下来.

cancelPeripheralConnection调用这个方法可能没有完成喔，看看苹果的注释

ios 蓝牙4.0 如何实现正确断开链接&&&
我打算在APP退出前台就断开链接，我在APPdelegate.m 的enterbackground 函数里直接调用了cancelPeripheralConnection：（CBPeripheral *）peripheral；但是总是出现程序死掉，哪位大侠能否帮我解答下。谢谢!

你要把central设置成viewcontroller的属性，去调用断开链接的方法。然后在APPdelegate.m 的enterbackground 函数里获取到那个viewcontroller。

centralManager不是同一个对象？原生的corebluetooth使用起来很麻烦，有很多委托，执行代码的位置非常跳跃。你可以试试这个蓝牙库BabyBluetooth，它简化了corebluetooth复杂的委托方法和来回跳跃式编程的问题。
