# CBConnectPeripheralOptionEnableTransportBridgingKey

An option to bridge classic Bluetooth technology profiles, if already connected over Bluetooth Low Energy.

```
let CBConnectPeripheralOptionEnableTransportBridgingKey: String
```

## Discussion

This option tells the system to connect non-GATT profiles on classic Bluetooth devices, if there is a low energy GATT connection to the same device.

The value associated with this key is an <doc://com.apple.documentation/documentation/Foundation/NSNumber> as a Boolean value. A `true` value instructs the system to bring up classic transport profiles when a low energy transport peripheral connects. A `false` value tells the system not to use the profiles.
