srnet:
So what has changed ?In your first post you said "bluetooth is not discoverable".
Cant see how your going to get a message that the PIN or passkey is incorrect if you cannot even see the Bluetooth module ?
I tryed to connect to USB bluetooth module (Class 1, version 4.0). With notebook (not know version atm) and now with two smartphones. First two tryes ended soon because BT modul is not discoverable. Smartphones can see BT modul but can not pair with it (because of problem with PIN or passkey which I never input / it never ask for it) ... So 4 devices - zero success. This modul can not be true certified Bluetooth.
