MAVLink commands (MAV_CMD) and messages are different! These commands define the values of up to 7 parameters that are packaged INSIDE specific messages used in the Mission Protocol and Command Protocol. Use commands for actions in missions or if you need acknowledgment and/or retry logic from a request. Otherwise use messages.
