WebSerial is a remote terminal to log, monitor or debug your firmware without being connected by wire. It lives on your wireless microcontroller itself and can be accessed anytime through your browser.

Note: This documentation serves both the versions of WebSerial ( Lite - Open Source and Pro ). Therefore, if you notice "(Pro)" mentioned on any of the features in the documentation, that means it is only available in WebSerial Pro.
