VM8090 command description

Hello, we wish to connect VM8090 to Android USB for our client. We are dev.company and need a documentation about set commands like 21h, etc, but we don’t find anything on your web site. Basically the comm. protocol description. I can assume that that kind of documentation exist, where can we find it?

Thank you


is this what you need?
It’s the software package.
Then go to
C:\Program Files (x86)\Velleman\K8090\Help
The protocol manual is located there.

That’s it. Thank you!
