# writeWithoutResponse

A property that indicates a peripheral can write the characteristic’s value, without a response to indicate that the write succeeded.

```
static var writeWithoutResponse: CBCharacteristicProperties { get }
```

## Discussion

Use the [`writeValue(_:for:type:)`](/documentation/CoreBluetooth/CBPeripheral/writeValue(_:for:type:)) method of the [`CBPeripheral`](/documentation/CoreBluetooth/CBPeripheral) class to write to a characteristic’s value, using the [`CBCharacteristicWriteType.withoutResponse`](/documentation/CoreBluetooth/CBCharacteristicWriteType/withoutResponse) constant as the parameter for `type`. If a characteristic has this property set, it doesn’t return an error to the central when it fails to write the characteristic’s value.
