ADS-B Receiver Project Setup Scripts
When installation starts, keep on saying NO to all options offered, till you reach the offer to install “Web Portal”. Say OK to it. The graphs are part of web portal.
Note: Dont say OK to “Advance Option” offered during web portal installation. The Advance Option results in storing the historic data, and in due course your microSD card will become full.
