```

## Discussion

The value of this property is an array of [`CBDescriptor`](/documentation/CoreBluetooth/CBDescriptor) objects that provide more information about a characteristic’s value. For example, they may describe the value in human-readable form and describe how to format the value for presentation purposes. For more information about characteristic descriptors, see [`CBDescriptor`](/documentation/CoreBluetooth/CBDescriptor).
