Why does voxl-inspect-pose -f fail when voxl-vision-px4 -b command is executed ?

The following is my voxl version:

voxl-inspect-pose -fshows nothing:waiting for server at /run/mpa/vvpx4_body_wrt_fixed/Why is it happening?

The partial packet read error usually occurs when there is a version mismatch between packages (i.e. the size of the packet has been updated and one package has the new size but another doesn't). If you update all of your packages together this issue should go away.
