Hi,
I am looking for some help debugging a nanoBTS setup with OpenBSC/SGSN/GGSN as I am
struggling getting GPRS to work.
I am seeing the following error in the SGSN output:
debian4:/opt/openbsc/openbsc/src/gprs# ./osmo-sgsn -c osmo_sgsn.cfg

I came across this thread http://comments.gmane.org/gmane.comp.mobile.openbsc.general/687
which talks about a similar error but hasn't helped resolve the problem.
I have a second hand nanoBTS unit, are there any configuration settings I need to change
on the unit itself to make it work with the example configs from OpenBSC?
Any help/advice much appreciated
Thanks
Jon
