I had a question about using the px4flow w/sonar. In mp, optical flow and sonar are two different hardware options. if i only have the px4flow w/sonar do i only need to enable optical flow? what about sonar/rangefinder? do i need to set that as well?
also if i use the px4flow w/sonar and a stand alone sonar, would i enable both optical flow and sonar/rangefinder? is this supported or should i use the px4flow w/out sonar and two stand alone sonar modules.
