GPX convertion issues

Hope this is the best place to post this.

I know this has been a topic before, but that was 3 years ago.
Seems the problem has resurfaced.

I am running Arducopter v3.3.3, and Mission Planner v1.3.39
The Datalogs do not create proper GPX files.
The GPX files are empty except for some small info.
The KMZ files look ok.
Even if I us the “Create KML+gpx” button, the result is the same.

Looking over my previous log dumps, I can see that with Arducopter v3.3.0, the GPX files created without any issues.

So something has changed from v3.3.0 to v3.3.3.

This is what the current GPX file looks like.
"gpx creator=“Mission Planner build 1.1.6079.34266 APM:Copter V3.3.3 (acf2e10c)” xmlns=“”></gpx"
That’s all that is in there.

And as you can see that I even updated to the latest MP beta version.

Any insight would be much appreciated.

can you please post the bin log file? so I can test

for some reason there are no ATT messages in your log. ie no roll or pitch values.

this is why it is failing. the gpx records this data, and because it doesn’t exist, it fails

Thanks Michael…you’re right. It was the missing ATT data.
I disabled some parts of the logging because I didn’t want the logs filled with EKF data.

I re-enabled the ATT Med logging and just tested it.
GPX is now populated.

This is good information to know.
I thought it had something to do with missing GPS data.
