I don't understand the connection. At the RFCOMM level there are Channel numbers, and there's no such thing as a default port. If one want to connect to ObexPushProfile, then one looks up that service by its 128-bit UUID in the peer's Service Discovery Database with SDP, and the returned record includes the RFCOMM Channel Number to connect to.
