     The uXRCE-DDS client module can synchronize the timestamp of the messages exchanged over the bridge.
     This is the default configuration. In certain situations, for example during [simulations](../ros2/user_guide.md#ros-gazebo-and-px4-time-synchronization), this feature may be disabled.

     Setting this parameter to any value other than `-1` creates a namespace with the prefix `uav_` and the specified value, e.g. `uav_0`, `uav_1`, etc.
     See [namespace](#customizing-the-namespace) for methods to define richer or arbitrary namespaces.

    If provided, this option changes the ROS 2 topic name of the advertised uORB topic appending the instance number: `fmu/out/[uorb topic name][instance]` (plus eventual namespace and message version).
    In the example above the final topic name would be `/fmu/out/vehicle_imu1`.
