I could not find the information online. There are many laser rangefinders delivered with Bluetooth and an application. But I wonder if these devices are / could be seen as an ordinary keyboard. I mean, getting a distance will send it to the smartphone as if the user had typed it (which makes most barcode readers do).
Is this the most common behavior? Do only some of them do that? Or not any?
I am working on a web application and it would be nice to enter real world dimensions directly into the application.
Sorry if the subject is off topic, but I could not find an associated stack exchange.
