/*!
 * \brief The QBluetoothLeUartDeviceModel class can be used to display available devices in a QML ListView.
 *
 * Example implementation:
 * \code{.qml}
 * import de.itsblue.bluetoothleuart 1.0
 *
 * QBluetoothLeUartClient {
 *     id: ble
 *     Component.onCompleted: {
 *         ble.startScanningForDevices()
 *     }
 * }
 *
 * ListView {
 *     model: ble.availableDevicesModel
 *
 *     delegate: ItemDelegate {
 *         width: parent.width
 *
 *         text: name
 *
 *         onClicked: backend.bleController.connectToDevice(device)
 *     }
 * }
 * \endcode
