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
<0011> gprs_ns.c:151 NSVCI=65534 Creating NS-VC

<0013> gprs_llc.c:700 LLC RX: unknown TLLI 0x7f60277f, creating LLME on the fly

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
