Thanks Marcel,

What I know about the device is that its command interface (UART) uses a 
frame protocol, with start and end delimiters of frames, frame ids and 
so on. I understand from your words that this is the standard way to 
communicate and that all devices have the same set of commands.

Anyway, I will check what you mention about hciattach. Is there any kind 
of documentation on how to do this, or I must dig into the code?

Thanks again,

David
