Both of my Raspberrys are still running fine with the database extracted from VRS and my modified markers.js. That’s three days now so as @obj said, it obviously WAS something else that caused them to choke and I just have to accept that I’ll probably never know what it was.
Having proved that VRS data can be extracted and converted to update dump1090-fa, I’m happy but as previously mentioned, I think there are too many problems with sharing data to be practical and users would need to have an instance of VRS running.
The thing is that running the extracted data through the toolchain involves downloading and installing dependencies that may only be needed for that one operation and requires skills beyond some users’ abilities.
Even if the process could be simplified and automated, if a user has VRS running, would they even care about the data being shown in Skyview?
I hardly ever look at it myself and only embarked on this project to see if it was possible.
