What is voxl-px4-imu-server? what is the use of it?

Hi,
Unlike voxl and voxl2, the rb5 board stack does not have an imu that's easily acessible from the applications layer, just the one hooked up to px4. Px4 imu server reads the imu data coming from px4 and mimics the output behavior of the normal imu server by doing some timestamp adjustment/roation to the correct frame/etc so that the rest of the voxl sdk which relies on imu data (such as qvio) can work properly.

@Alex-Gardner for voxl2 can I disable it then ?

Yes, the service doesn't need to be enabled on voxl/voxl2 (the configure-mpa script will enable the correct imu server for whichever platform you're on)
