Supports a platforms=["ros"] query where you can specify a single type of command platform to return for. This allows multiple listeners to take different commands from the robot. ros is the current publicly supported platform and other private ones are used within mission_control to direct messages correctly. If you do not specify a platform, it will return all commands, which is not the best practice.
Other platforms include ['ros', 'mission_control_link', 'mission_control_controller'].
This must only be called by the device or commands will be lost
