I've got a samsung nexus with android 4.3 with a few contacts (just for
testing). The phone is paired over bluetooth with my laptop. I did an initial
sync with those commands:

syncevolution --configure \
                syncURL= \
                addressbook/backend=pbap \
                addressbook/database=obex-bt://$mac_addr \
                target-config@pbap addressbook

syncevolution --configure \
                --template SyncEvolution_Client \
        --keyring=no \
                syncURL=local://@pbap \
                pbap

syncevolution --sync refresh-from-client pbap addressbook

This imports all contacts perfectly. Then on the android phone I edit a contact
and add an email address, and run that command on laptop to sync:

syncevolution pbap addressbook

And it says there are no changes. If I do that it works:

syncevolution --sync refresh-from-client pbap addressbook
