Hello all,

I want to edit the source code for the offboard mode (follow_tag). Can you please tell me where can I fine it inside the Voxl? and after editing how should I build it to be able to make it work? 

I want to change the z distance between tag and the drone from 1.5m which is right now, to 0.3m.

Thank you,

@Pooyan Here is a link to the code: https://gitlab.com/voxl-public/voxl-sdk/services/voxl-vision-hub/-/blob/dev/src/offboard_follow_tag.c?ref_type=heads#L171. Build instructions are in the README file.
