Hi all, I have configured QGC to read the battery voltage of the drone battery and it works fine. Is there a way to get a log file of this voltage reading? Any help is appreciated. Regards, Hasini

QGC can save telemetry logs. Or you can download binarys logs from the vehicle.

Thank you for the response :slight_smile: This might be a stupid question. But, are the voltage readings logged in telemetry logs too? Regards, Hasini

Everything comes to QGC over mavlink telemetry. So if you can see a value in QGC ui, then it’s in the telemetry logs somewhere.
