蓝牙协议

1 首先我带入了BLE包，实现蓝牙协议

2 扫描周围的蓝牙设备

 self.beaconFinder = [KRBeaconFinder sharedFinder];

    

    __weak typeof(self) weakSelf = self;

    [_beaconFinder setBleScanningEnumerator:^(CBPeripheral *peripheral, NSDictionary *advertisements, NSNumber *RSSI)

     {

//         NSLog(@"The advertisement with identifer: %@, state: %d, name: %@, services: %@,  description: %@",

//               [peripheral identifier],

//               [peripheral state],

//               [peripheral name],

//               [peripheral services],

//               [advertisements description]);

         

         

         //过滤（hasPrefix）

         if ([peripheral.name hasPrefix:@"XY"]) {

             

             if (![weakSelf.detectedBeacons containsObject:peripheral]) {

                 [weakSelf.detectedBeacons addObject:peripheral];

                 [weakSelf.beaconTableview reloadData];

             }

         }

         

     }];

//启动

    [_beaconFinder bleScan];

3 连接蓝牙设备

    [[KRBeaconCentralManager sharedManager].centralManager connectPeripheral:beacon options:[NSDictionary dictionaryWithObject:[NSNumber numberWithBool:YES] forKey:CBConnectPeripheralOptionNotifyOnDisconnectionKey]];

3.1 连接设备成功后会回调一个方法

-(void)centralManager:(CBCentralManager *)central didConnectPeripheral:(CBPeripheral *)peripheral

{

    //...

      

}

4 外设设置代理以便以后数据交流

peripheral.delegate = self;

5 查询蓝牙服务

[peripheral discoverServices:nil];

5.1蓝牙服务通知通过的回调

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

{

    

}

6 查询服务所带的特征值

[peripheral discoverCharacteristics:nil forService:service];

6.1返回的蓝牙特征值通知通过代理实现的回调方法

- (void)peripheral:(CBPeripheral *)peripheral didDiscoverCharacteristicsForService:(CBService *)service error:(NSError *)error

{   

}

7 给蓝牙发送数据

[peripheral readValueForCharacteristic:service.characteristics[0]]

7.1 给蓝牙发送数据成功的代理回调方法

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

{

}

8 处理蓝牙发过来得数据的回调方法

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

{

    [ peripheral writeValue:tempData forCharacteristic:characteristic type:CBCharacteristicWriteWithResponse];    

}

个人敲了一下测试过的，希望有大神帮忙指点一下。。。。。。。。。。。。。。。。
