如何正确实现didReceiveWriteRequests？ iOS6的CoreBluetooth

我实现的iOS客户端CoreBluetooth服务器&用于发送数据如何正确实现didReceiveWriteRequests？ iOS6的CoreBluetooth

client site 
[self.connectedPeripheral writeValue:mainData forCharacteristic:characteristic type:CBCharacteristicWriteWithResponse];

和

- (void)peripheral:(CBPeripheral *)peripheral didWriteValueForCharacteristic:(CBCharacteristic *)characteristic 
{ 
    NSString *s= [[NSString alloc] initWithData:characteristic.value encoding:NSUTF8StringEncoding]; 
    NSLog(@"didWriteValue characteristic.value: %@ ", s); 
}

和服务器站点

- (void)peripheralManager:(CBPeripheralManager *)peripheral didReceiveWriteRequests:(NSArray *)requests 
{ 
    NSData *res= [[NSString stringWithFormat:@"Hello"] dataUsingEncoding:NSUTF8StringEncoding]; 
[self.peripheral updateValue:res 
         forCharacteristic:self.writeCharacteristic 
        onSubscribedCentrals:nil]; 
[peripheral respondToRequest:aReq withResult:CBATTErrorSuccess]; 
}

但是，客户端无法接收任何数据。有什么想法？感谢您的帮助。

你发现任何回答您的问题？我也有同样的问题：（ – eter

要使用：

- (BOOL)updateValue:(NSData *)value forCharacteristic:(CBMutableCharacteristic *)characteristic onSubscribedCentrals:(NSArray *)centrals;

首先需要使用

- (void)setNotifyValue:(BOOL)enabled forCharacteristic:(CBCharacteristic *)characteristic;

从客户端订阅它。

根据苹果的CoreBluetooth文档，你应该使用：

- (void)respondToRequest:(CBATTRequest *)request withResult:(CBATTError)result;

回复的central.This也是一种选择，当你收到读请求
