CoreBluetooth使用 （服务端中心设备）

自己写了一个Demo    下载地址：http://download.csdn.net/detail/i_k_o_x_s/9031359

CBCentralManager类


//初始化的时候 调用代理方法   返回当前设备的蓝牙状态

- (void)centralManagerDidUpdateState:(CBCentralManager *)central

//开始扫描周边蓝牙设备
 停止扫描
 serviceUUIDS  options  为nil  不指定搜索条件

- (void)scanForPeripheralsWithServices:(NSArray *)serviceUUIDs options:(NSDictionary
*)options;

- (void)stopScan;

//  当设备搜索到周边蓝牙设备的时候  回调代理方法
   peripheral  设备        advertisementData   设备广告发出来的信息   RSSI  设备强度

-(void)centralManager:(CBCentralManager *)central didDiscoverPeripheral:(CBPeripheral
*)peripheral advertisementData:(NSDictionary *)advertisementData RSSI:(NSNumber *)RSSI

// 连接指定蓝牙设备

- (void)connectPeripheral:(CBPeripheral *)peripheral options:(NSDictionary *)options;
//取消连接指定蓝牙设备

- (void)cancelPeripheralConnection:(CBPeripheral *)peripheral;

// 和周边蓝牙设备连接成功  回调代理方法

-(void)centralManager:(CBCentralManager *)central didConnectPeripheral:(CBPeripheral
*)peripheral
{
//设置代理
    peripheral.delegate =self;
    [peripheral discoverServices:nil];
}

// 和周边蓝牙设备连接失败  回调代理方法

-(void)centralManager:(CBCentralManager *)central didFailToConnectPeripheral:(CBPeripheral
*)peripheral error:(NSError *)error

CBPeripheral类
CBPeripheralDelegate 代理
// 外部设备寻找到服务后   回调代理方法

-(void)peripheral:(CBPeripheral *)peripheral didDiscoverServices:(NSError *)error{

// 外围设备查找指定服务中的特征  服务
- (void)discoverCharacteristics:(NSArray *)characteristicUUIDs forService:(CBService
*)service;

//外围设备寻找到特征后    回调代理方法
-(void)peripheral:(CBPeripheral *)peripheral didDiscoverCharacteristicsForService:(CBService
*)service error:(NSError *)error{

// 设置激活通知  到指定特征
- (void)setNotifyValue:(BOOL)enabled forCharacteristic:(CBCharacteristic *)characteristic;

//特征值被更新后  回调代理回调
-(void)peripheral:(CBPeripheral *)peripheral didUpdateNotificationStateForCharacteristic:(CBCharacteristic
*)characteristic error:(NSError *)error{

// 订阅特征 更新数据   回调代理方法

characteristic.value 为特征发过来的数据

-(void)peripheral:(CBPeripheral *)peripheral didUpdateValueForCharacteristic:(CBCharacteristic
*)characteristic error:(NSError *)error
//客户端  CBPeripheralManager类 调用这个方法
                - (BOOL)updateValue:(NSData *)value forCharacteristic:(CBMutableCharacteristic *)characteristic
onSubscribedCentrals:(NSArray *)centrals;

//写入数据到指定特征   客户端会接收回调代理方法

- (void)writeValue:(NSData *)data forCharacteristic:(CBCharacteristic *)characteristic
type:(CBCharacteristicWriteType)type;
//客户端  CBPeripheralManager类 调用这个方法

-(void
b712
)peripheralManager:(CBPeripheralManager *)peripheral
didReceiveWriteRequests:(NSArray *)requests{

  //成功写入后回调的代理方法

- (void)peripheral:(CBPeripheral *)peripheral didWriteValueForCharacteristic:(CBCharacteristic
*)characteristic error:(NSError *)error
