# CBCharacteristicProperties

Values that represent the possible properties of a characteristic.

```
struct CBCharacteristicProperties
```

## Overview

Since you can combine characteristic properties, a characteristic may have multiple property values set.

## Topics

### Creating a Characteristic Properties Instance

[`init(rawValue:)`](/documentation/CoreBluetooth/CBCharacteristicProperties/init(rawValue:))

Creates a characteristic properties instance from the given raw value.

### Characteristic Properties

[`CBCharacteristicPropertyBroadcast`](/documentation/CoreBluetooth/CBCharacteristicProperties/broadcast)

A property that indicates the characteristic can broadcast its value using a characteristic configuration descriptor.

[`CBCharacteristicPropertyRead`](/documentation/CoreBluetooth/CBCharacteristicProperties/read)

A property that indicates a peripheral can read the characteristic’s value.

[`CBCharacteristicPropertyWriteWithoutResponse`](/documentation/CoreBluetooth/CBCharacteristicProperties/writeWithoutResponse)

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

[`CBCharacteristicPropertyWrite`](/documentation/CoreBluetooth/CBCharacteristicProperties/write)

A property that indicates a peripheral can write the characteristic’s value, with a response to indicate that the write succeeded.

[`CBCharacteristicPropertyNotify`](/documentation/CoreBluetooth/CBCharacteristicProperties/notify)

A property that indicates the peripheral permits notifications of the characteristic’s value, without a response from the central to indicate receipt of the notification.

[`CBCharacteristicPropertyIndicate`](/documentation/CoreBluetooth/CBCharacteristicProperties/indicate)

A property that indicates the peripheral permits notifications of the characteristic’s value, with a response from the central to indicate receipt of the notification.

[`CBCharacteristicPropertyAuthenticatedSignedWrites`](/documentation/CoreBluetooth/CBCharacteristicProperties/authenticatedSignedWrites)

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

[`CBCharacteristicPropertyExtendedProperties`](/documentation/CoreBluetooth/CBCharacteristicProperties/extendedProperties)

A property that indicates the characteristic defines additional properties in the extended properties descriptor.

[`CBCharacteristicPropertyNotifyEncryptionRequired`](/documentation/CoreBluetooth/CBCharacteristicProperties/notifyEncryptionRequired)

A property that indicates that only trusted devices can enable notifications of the characteristic’s value.

[`CBCharacteristicPropertyIndicateEncryptionRequired`](/documentation/CoreBluetooth/CBCharacteristicProperties/indicateEncryptionRequired)

A property that indicates only trusted devices can enable indications of the characteristic’s value.
