I just installed the version 1.0.1 of olympe and I tried the example code from the documentation.

Sometime this work it works normally, but other time I get this error.

Thank you,

Thanks for this bug report.

Olympe 1.0.1b has now been released and should fix this issue. You should update your GroundSDK workspace with the following commands.

$ repo sync
$ ./build.sh -p olympe-linux -A all final -j

I seems to work,

Thank you
