logdata files empty

[Mitteau]

Hello everybody !
I have a problem:
I want to register logdata files of some flight data from crazyflie.
The data are correct in the plotter tag, but some files in config/logadata are totally empty.
Only one of the writing is correct, 100ms-stabilizer. The other files are empty, although data appear in plotter.
Thanks for help !

Might be a silly question but have you checked the "Write to file" checkbox in the Log Blocks tab?

[Mitteau]

Thanks !
Not so silly ! But write file was checked and works only for stabilizer block...

Are you using a recent firmware? We reached the limit of possible log block in the most recent client that requires to update the firmware to add new log blocks (we increased the max number of log block in the firmware).

[Mitteau]

Yes, I installed version 2017.04...

Can you try with 2017.5: https://github.com/bitcraze/crazyflie-c ... ag/2017.05

I download yesterday last commits from github, but as my cf2 is our of service, we must wait one week to test the new firmware. I will stay in contact. Jean-Claude

Hello
I get yesterday my new cf2.
Today, 3 logdata are running: stabilizer, motors, baro. zrange, battery, althold does not are written in files althongu correctly shown on plotter tab.
...
The versions are:
1/ firmare, commit master/e4b3193
2/ python client, commit master/2378d47
3/ lib, commit master/fa726da
PC system is Debian 8.8

Hmmm, so you have ticked the write to file checkbox and nothing shows up in the log folder? You can open the log folder from the client.

[Mitteau]

Yes, but today, there are only battery and z-range which do not write anything.
How can I read logdata from client ?
