Command data VM201

I would have liked to use the VM201 via the application demopad.
For this, command data must be created to connect with a button created in the demopad application
Are there examples regarding the structure of the command data?

Hi

This is available on our website

Under Downloads->info sheets → Protocol

I would like to make a reference to the app. For this I need a url. What is the url for the VM201 app?
