Why there is no voltage log?

PX4 Autopilot

Anyone can help?

EDIT: SDLOG_PROFILE=2047

Do you have a power module connected and correctly configured? Do you see the voltage in QGC?

Yes, I saw voltage in QGC. I have MicroAir H743 AIO V2, which has Voltage&Current Monitoring feature.

Looks like the voltage is in the log and flight review doesn’t display it:

Not sure why. I’m pinging @bkueng to check.

Thanks for confirming and sharing that PlotJuggler can display the voltage data from the ulog file. Could you please clarify what the unit of the x-axis represents? Is it in seconds?

The problem was that it’s a log from an older PX4 version that does not contain the internal_resistance_estimate message field. I’m adding a check for that here: fix battery plots: check for 'internal_resistance_estimate' data field by bkueng · Pull Request #314 · PX4/flight_review · GitHub
