我实现了iOS CoreBluetooth客户端和服务器来发送数据

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.任何的想法？谢谢你的帮助.
