# isAdvertising

A Boolean value that indicates whether the peripheral is advertising data.

```
var isAdvertising: Bool { get }
```

## Discussion

This value is <doc://com.apple.documentation/documentation/Swift/true> if the peripheral is advertising data as a result of successfully calling the [`startAdvertising(_:)`](/documentation/CoreBluetooth/CBPeripheralManager/startAdvertising(_:)) method. The value is <doc://com.apple.documentation/documentation/Swift/false> if the peripheral is no longer advertising its data.
