Now it starts to be interesting ;)

This stuff is performed to get the necessary informations from the
mobile. We could implement every other AT command to get informations
from the mobile if we need it.

This should be the warning about an unknown Samsung mobile.

Any ideas what AT$TSSPCSW=1 means?

The mobile does not answer and this means our message is wrong. So the
libsyncml OBEX code generally work we have just to modify it for your
Samsung E250.

First we need the correct AT command sequence. So do you know AT$TSSPCSW=1?

P.S. I go on holidays at Friday. So I think we cannot fix the issue
until September.
