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
serviceUUIDSoptions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)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
