Is ubuntu setting really using obexd? Or perhaps they are setting a Channel on CreateSession which is then forcing to use RFCOMM instead of L2CAP ERTM, when you use obexctl and don't set any Channel it will attempt to discover the record using SDP and if there is an entry for L2CAP channel it will use to connect using ERTM. -- Luiz Augusto von Dentz
