Question

我正在这样向BLE外围设备编写命令。

- (void)peripheral:(CBPeripheral *)peripheral didDiscoverCharacteristicsForService:(CBService *)service error:(NSError *)error {
if(error) {
    //        [self cleanup];
    NSLog(@"%@", [error localizedDescription]);
    return;
}

unsigned char bytes[] = {0xA0,0x05,0xF1,0xF2,0xCC,0xFE};
NSData *data = [NSData dataWithData:self.mutableData];
data = [NSData dataWithBytes:bytes length:sizeof(bytes)];

if([service.UUID isEqual:[CBUUID UUIDWithString:kServiceUUID]]) {
    for(CBCharacteristic *characteristic in service.characteristics) {
        if([characteristic.UUID isEqual:[CBUUID UUIDWithString:kWriteCharactersticUUID]]) {
            self.discoveredCharacteristic = characteristic;
            [self.discoveredPeripheral writeValue:data forCharacteristic:characteristic type:CBCharacteristicWriteWithResponse];
        } else if([characteristic.UUID isEqual:[CBUUID UUIDWithString:kNotifyCharactersticUUID]]) {
            self.notifyCharacteristic = characteristic;
        }
    }
  }
}

但是，如果我这样编写，则其他委托方法无法调试。而且如果我使用CBCharacteristicWriteWithResponse，我会收到这样的错误

错误域= CBATTErrorDomain代码= 3“不允许写。  UserInfo = {NSLocalizedDescription =不允许写。}

我用LightBlue应用程序测试了BLE设备，它显示为，该属性用于Write Without Response。

您能请谁帮助我吗？
