Please can you explain how to bridge complex messages like cmd_vel (geometry_msgs/Twist)? Thank you in advance

A similar need here. I'd like to bridge the sensor_msgs/Imu data.

msg_type: geometry_msgs.msg:Twist

You can simply define the complex message type in demo_params.yaml.

factory: mqtt_bridge.bridge:RosToMqttBridge msg_type: sensor_msgs.msg:Imu topic_from: imu topic_to: ping factory: mqtt_bridge.bridge:MqttToRosBridge msg_type: sensor_msgs.msg:Imu topic_from: ping topic_to: /pong
