if you see a pin code or a link key request before the connect complete
event, then at least one device is in security mode 3.

For devices in security mode 2, the service (profile) decides when to
requests authentication (pairing). If you have an OBEX push profile
running which normally doesn't needs authentication, then what is the
difference compared to security mode 1?

Forget about the crappy security modes, because they are useless. The
only important thing is mode 1. It says that both sides must support it
and that you must authenticate before you can start encryption.
