Dear Alexander,
Will do the wiki update as soon as I have (at least a more or less) working setup.
A single question: can you comment on the non-connecting PCU socket? To my best
understanding, this connection is a normal UNIX socket, and the PCU and the SGSN should
find each other if they compiled in a given order to meet some dependency.
Is there any specific flag we need to enable during compiling any of the related software?
(Osmo-BTS, PCU, OpenBSC, etc.)
Regards,
Csaba

Sipos, Omar,
Yes, 'fariwaves/master' is almost always the best choice if you're using
USRP or UmTRX. The wiki should be updated to reflect that - your help would
be greatly appreciated here. You may also find documentation at
umtrx.org
useful, even though it's focused on UmTRX and not USRP.
Regarding GPRS issues I hope Ivan will be able to comment.

Hi Omar,
I am trying to do the same thing for a while, but I am not succeeded yet.
The hardest is to find the right branch of every piece of software.
The wiki is quite outdated, and no USRP related man page was ever created.
The jolly branches are also quite old, a lot of development happened, so I
would not suggest to use them.
Tom suggested to me that I should try fairwaves/master branch of OpenBSC,
Osmo-BTS and Osmo-TRX (pretty much everything that has a fairwaves/master
branch) to use with USRP devices. I also have a B200 by the way.
With this at least I was able to build a fairly recent version that starts
up and actually transmits, I think the PCU was not able to talk with the
SGSN (which is part of OpenBSC), so probably I need some more fine tuning.
There was a UHD driver problem a few months back, so the UHD driver version
is also important. This problem affected OpenBTS, I don't know what is the
recommended UHD version, maybe Tom will come in and advise us something.
Just to notify the list, I am more than happy to create a new Wiki page in
the minute I find a working configuration.
At least I am not alone with this anymore :-)
Regards,
Csaba

Tárgy: Using GPRS
Hi list,
I've installed omsocom for the first time on a USRP B200 and I'm interested
in trying out the GPRS stack. I've followed a few pages on the wiki, namely
http://openbsc.osmocom.org/trac/wiki/network_from_scratch and
http://openbsc.osmocom.org/trac/wiki/OpenBSC_GPRS to get set up and I am
not sure how up to date these tutorials are. I have calls working via the
LCR, but I cannot get GPRS functioning. I see no activity on the BSC log
when attempting GPRS attach using APN openbsc. I also see no traffic
between the SGSN and the BSC (listening with tshark on 127.0.0.1:23000).
Any help is appreciated.
I am currently using osmo-trx/master, osmo-bsc/jolly/testing,
libosmo-abis/jolly/multi-trx, omso-bts/jolly/trx, openggsn/master, and
osmo-pcu/master.
Best,
Omar
