I wanna get a reference software to demo voxl features such as VIO, VOA, offboard control with follow mode with apriltag and precision landing with apriltag.

do you have demo software?

I have a voxl flight-deck hardware and I tried to test voxl-vision-px4 software version 0.8.1 and 0.6.8.

But, I didn't fully verify whole feature.

Q1) which software version is prefer to test all feature for voxl flight?

Q2) I downloaded voxl-vision-px4(0.6.8) clone from gitlab. and built by my self. 
but, It invoked some errors related with dependencies in build process. 
(I could not use voxl-vision-px4(0.8.1) version to test VIO and other vision processing.)

could you please let me which commit is correct to build without error for version 0.6.8?

thanks

voxl-suite ties all of the packages together. I will try to get you the right version for your testing. 

We are targeting getting the mainline back to feature parity ASAP. Sorry for the confusion.

voxl-suite 0.2.0 was that last version that supported VOA and Apriltag localization. If you install that version, those features will be available.

Thanks Alex! voxl-suite 0.2.0 can be found here: https://gitlab.com/voxl-public/utilities/voxl-suite/-/tree/v0.2.0

@Alex-Gardner 
Does this mean that apriltag relocalization is still unavailable for voxl-suite 0.3.4?

@PawelJ Maybe. I couldn't test VOA and apriltag function with version 0.3.4.
