Flight Log

[DMarc8]

Hello,

I know that in the default configuration, flight log files are generated in the folder /var/lib/mavlink-router. I tried to analyse one of the .ulg files using the software pyFlightAnalysis. While I'm able to display flight data from a sample log file, when I load the log file from intel drone I don't get anything. Are there some parameters to change in order to correctly generate the log file ?

Has anyone been able to get and display flight log data correctly?

Hello daniele.marchetti,

Thank you for your interest in the Intel Aero Ready to Fly drone.You may find this guide helpful: https://dev.px4.io/en/log/flight_log_analysis.htmlRegards,Alexandra

I have already read that guide. Following that, I'm able to analyse flight data from a sample.ulg file, but when I try to analyse flight data from one of the .ulg file of the folder /var/lib/mavlink-router I don't get anything. For this reason I would like to know if there is anyone able to do it.

(I'm running Ubuntu 16.04, the last flight controller firmware and FPGA)

Thank you in advance,

Daniele

Hi daniele.marchetti,

Could you give me more details?What do you mean "you don't get anything" when you try to analyse a file? What happens when you open the .ulg file? Did you try several .ulg files? Can you also send screenshots?Thank you,Alexandra

Hello daniele.marchetti,

We were able to see flight log with the DroneKit guide tools:

• Online - https://logs.px4.io/ https://logs.px4.io/
• pyulog - built from source

Could you please try one of these 2 tools and let us know if you managed to read the log files? Thank you,Eliza

Hello Eliza,

I apologize for replying late. Now I'm able to read correctly the log files using both the tools you have suggested. I can load the .ulg file on https://logs.px4.io/ https://logs.px4.io/

and plot data online or use pyulog to convert the .ulg into many .csv files and then import and plot them using Matlab.

Thank you for your support.
