# CBConnectPeripheralOptionEnableTransportBridgingKey

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

## Declaration

```swift
let CBConnectPeripheralOptionEnableTransportBridgingKey: String
```

## Discussion

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 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.
