# NSBluetoothPeripheralUsageDescription

A message that tells people why the app is requesting the ability to connect to Bluetooth peripherals.

## Discussion

For apps with a deployment target of iOS 13 and later, use [`NSBluetoothAlwaysUsageDescription`](/documentation/BundleResources/Information-Property-List/NSBluetoothAlwaysUsageDescription) instead.

For deployment targets earlier than iOS 13, add both [`NSBluetoothAlwaysUsageDescription`](/documentation/BundleResources/Information-Property-List/NSBluetoothAlwaysUsageDescription) and [`NSBluetoothPeripheralUsageDescription`](/documentation/BundleResources/Information-Property-List/NSBluetoothPeripheralUsageDescription) to your app’s [`Information Property List`](/documentation/BundleResources/Information-Property-List) file. Devices running earlier versions of iOS rely on [`NSBluetoothPeripheralUsageDescription`](/documentation/BundleResources/Information-Property-List/NSBluetoothPeripheralUsageDescription), while devices running later versions rely on [`NSBluetoothAlwaysUsageDescription`](/documentation/BundleResources/Information-Property-List/NSBluetoothAlwaysUsageDescription).

> Important:
> This key is required if your app uses APIs that access Bluetooth peripherals and has a deployment target earlier than iOS 13.
