Hi,  
I have an Intel Aero RTF running ubuntu.  
I’m trying to find a solution to get the log files from the drone but there is a problem with it as you can see in the following picture :

Firstly I tried to get them on my groundstation (W10) but after a lot of research I was not able to find a solution. Of course I clicked on refresh but nothing… I tried through wifi hotspot and ethernet-over-usb but nothing. I also tried to get them from Mavlink 2.0 Logging and nothing appears. I receive the information of the battery, GPS etc but not the log files. Moreover, the loss rate is around 20% on the ground station and 5% on QGC running on the Intel Aero directly.

Two main error messages appears:

- MAVLinkLogManagerLog: Start MAVLink log command failed. → by start logging on mavling 2.0 logging

- LogDownloadLog: Request log entry list ( 0 through 49 ) → by clicking on refresh

Can you help me please? Thank you 🙂

The Intel Aero does not have persistent storage for logs on the autopilot. Instead it streams the log data to the Linux companion. You can get via `scp`, they should be stored in `/var/lib/mavlink-router`.

Thank you!  
Is there a way to get them directly on QGC? By streaming them via UDP or sending them through ethernet-over-usb?

I think you could stream them, but you will have to disable logging in the mavlink-router config.
