Hi,
When using Dump1090, I can get JSON data via http://{my\_raspberry\_pi}:8080/data.json. I need this for a project I am running.
When I try to get to the same page when running the FlightAware version I get 404 not found. Is the JSON data still available at a different URL? I would like to be able to use the FlightAware version if possible, but if I can’t get to the JSON data I won’t be able to.
I have found http://{my\_raspberry\_pi}:8080/data/aircraft.json is close, but is missing two keys: validposition and validtrack. Is another URL that I haven’t found that includes those fields as well?
Thanks,
Ketih

aircraft.json is what you want. The format is indeed different between different versions of dump1090.
