IOS development, I want to upload a file (or stl) of. gsd. What should I do

  ios, question

The manager asked me to upload a gsd file to the equipment for machine identification operation. At present, I have only uploaded pictures, and it is not clear whether the gsd file can be uploaded. Ask for advice and upload various types of great god advice

No matter what files are, they are binary strings for machines. What is the difference?
