<![CDATA[voxl_qvio_server version problem]]>Hi,

I built the latest libmodal_json and libmodal_pipe from gitlab and the latest voxl_mpa_to_ros in a ROS medolic container. But when I tried to subscribe /qvio topic, I got this error,

RROR validating VIO data received through pipe: read partial packet
read 156 bytes, but it should be a multiple of 324

It turns out voxl_qvio_server is using a older version of libmodal_pipe. The data structure vio_data_t changed in the latest version.

What is proper solution for this?

Is there newer SDK with latest libmodal_pipe available I can upgrade to? Or should I build my container using the older version of libmodal_pipe?

Thanks,

Dong

The "platform release" that we ship is a system image paired with a release of the sdk, so that one that you flashed (3.8.0-0.7) is system image 3.8.0 alongside sdk 0.7, so you should use the sdk-0.7 repos.

Thanks!

My question if I use the latest stable binary release. Which label branch should to checkout to build mpa_to_ros in ROS melodic docker?

Thanks!

You can also pull from a specific release in your install-build-deps script. If your drone is on the 0.7 release and you'd like to make some modifications, you can checkout the sdk-0.7 tag, make your modifications, and run install-build-deps.sh sdk-0.7 to have everything from the last voxl1 stable release.

I'm not using the dev branch. I just build my mpa_to_ros using the master branch of libmodal_json, libmodal_pipe and voxl_mpa_to_ros.

If I upgrade my voxl seeker to the stable release of VOXL Platform 3.8.0-0.7, which branch should I use to build my package?

Thanks again!

See package configuration here: https://docs.modalai.com/configure-pkg-manager/
