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.
