（转）iOS蓝牙调用的一般流程

文章转自：http://www.cnblogs.com/ctaodream/archive/2013/07/03/3169962.html

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 *peripheraManager;

@property(strong,nonatomic) CBMutableCharacteristic *customerCharacteristic;

 @property (strong,nonatomic) CBMutableService *customerService;

3.调用流程代码中有注释
