OpenBTS with GPRS....trouble with SGSN and PCU

[altaf sk]

Thank you andreas for your reply.

I applied the patch and I can see the IMM ASS messages

1.

eg : On the PCU log

receiving IMM.ASS confirm from BTS: 2d 06 3f 10 0e 43 6c 7b 19 ce 00 00 c8
00 10 0b 2b 2b 2b 2b 2b 2b 2b

2. Branches

PCU -> master
bts   -> gprs-work
os_BB -> sylvain/testing
openbsc -> master

3.
I have attached Openbts.db and osmo-sgsn.cfg
I have checked for openbsc.cfg in the openbsc folder. but I find a
diiferent openbsc.cfg for different type of bts (nanobts,bs11, etc) but not
for openbts. I am not sure which one to attach.

When you mean by configs of openbsc. Is it the osmo-sgsn.cfg or
openbsc.cfg.? Can you please tell me which one is the correct cfg when
using openbts.


regards,

Altaf
