@Matt-Turi Thank you for your quick response.
After updating to v0.0.5, it worked!

Hello,

In voxl-mapper, the drone does not move even if I select "Follow Path" in "Plan Home" or "Plan to a Point".

The result of "voxl-mapper -d" shows "sending trajectory to plan channel", so it seems to be working fine.
But, voxl-vision-px4 shows the following error:

Jan 01 00:03:57 apq8096 voxl-vision-px4[2165]: ERROR validating trajectory data received through pipe: read partial packet
Jan 01 00:03:57 apq8096 voxl-vision-px4[2165]: read 7936 bytes, but it should be a multiple of 7940

Is there something wrong with the settings?

I used dev branch, and each version is as follows.

We are about to manufacture a custom prop guard for the seeker to feel safer about indoor usage. The concern is that some part of it might be visible in the field of view of tracking camera/ToF sensor. If it happens would it create a problem/ adverse conditions for VOXL to work properly?

Hi, I'd like to know how to backup the whole system settings and restore.
Does voxl-backup command save all the data to /data folder?
