We want use the Ardupilot firmware without modifying in our project with custom GCS, for commercial purpose. So, is it mandatory to publish the source code of our project ?
Thanks
I am not a lawyer or one of the code maintainers.
As I read it, you can use Ardupilot for commercial purposes as long as you either include the Ardupilot source code with the product, or include a written offer to provide the source code (which could be handled by simply pointing them at the upstream Ardupilot git repo as long as it’s still up and running).
I would not expect you to need to publish the source code for your GCS.
