web app

The good news is that there isn’t a long and complex software installation process to follow! 👍

The software for the d2 is a modern, clearn progressive web app that runs in Chrome .

Currently Safari browser from Apple does not support some of the required features to communicate with serial devices and so Safari does not work at this time. However, Chrome is supported on all all platforms such as Windows, Mac and Linux.
