Question

我实现iOS CoreBluetooth客户端＆amp;用于发送数据的服务器

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。

Answer 1

根据Apple在CoreBluetooth上的文档，你应该使用：

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

回复中心。当您收到阅读请求时，这也是一种选择

Answer 2

使用：

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

首先需要使用

订阅它

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

来自客户端。
