You raised a very good point. This feature will be an important step in our roadmap.
Currently, if your skill requires changing device file’s permission in MIND, the skill cannot be distributed from Skill Store.
We will release a new version of MIND which adds a simple API to allow skills to get the permission of low-level device files. You can do this manually on your HEXA as you are developing right now, and we’ll let you know once we release the new version.
In the long term, we will have protocols in MIND system to fully control video devices and also other devices files, in this way it will be more secure, and we can optimize the performance continuously. As I said before, this will be a very important step in our roadmap.
