Hi,
I want to customize QGC.
For each flight I want to add Flight entry to the db like
FlightStartTime, FlightEndTime, TotalTime, so on

Can anyone let me know the exact file from where I can get this data?

Hello @Vidya_Patil,
I am facing the same problem as mentioned by you in " [Solved] Need help in reversing the secure bootloader - #6 by Vidya_Patil? ". Did you find the solution for that?
