Thanks, I won't bother with the D-Bus interface then. But if the C API is being 
rewritten now, that sounds like there is currently no stable API available at 
all. :/ Or is it just the internals being rewritten?

So I assume, the fastest route the get a prototype that does something, would be 
to get gatt-example.c to run and then modify that, right?

Kind regards,
