# authenticatedSignedWrites

A property that indicates the perhipheral allows signed writes of the characteristic’s value, without a response to indicate the write succeeded.

```

## Discussion

Discussion If a characteristic has this property set, it returns an error to the central when it fails to write the characteristic’s value.
