mircondini it connects automatically for me. The data you see depends on the car and DuduOS integration. For my VW, I see more data. I don't use it with the DuduOS functionality at the moment though, because DuduOS acts like a (better) trip computer and I'm more interested in detailed information e.g. on clutch temperatures and DPF status, so I'm using it with Carscanner/VAG-DPF again. If I do that, the DuduOS functionality stops of course, as the (any) OBD Adapter can only serve one client (i.e. app) at a time.
PS: In case of connection issues, make sure you have the latest firmware on the adapter. See its manual, you need to update using their app.
