# AccessoryTransport.bluetooth

A transport method that uses Bluetooth for data delivery.

```
case bluetooth
```

## Discussion

This transport method prefers [`SecurityMessage.CipherSuite.xWing`](/documentation/AccessoryTransportExtension/SecurityMessage/CipherSuite-swift.enum/xWing) cryptography, but supports [`SecurityMessage.CipherSuite.p256`](/documentation/AccessoryTransportExtension/SecurityMessage/CipherSuite-swift.enum/p256) as a fallback. The system prioritizes this transport method when the accessory connection is active.
