Sipos Csaba sipos.csaba at kvk.uni-obuda.huDear 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 ----- Eredeti üzenet ----- Feladó: "Alexander Chemeris" <alexander.chemeris at gmail.com> Címzett: "Sipos Csaba" <sipos.csaba at kvk.uni-obuda.hu> Másolatot kap: "OpenBSC Mailing List" <openbsc at lists.osmocom.org>, "OMAR RAMADAN" <omar.ramadan at berkeley.edu> Elküldött üzenetek: Péntek, 2015. Július 24. 22:02:26 Tárgy: Re: Using GPRS 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. Please excuse typos. Written with a touchscreen keyboard. -- Regards, Alexander Chemeris CEO Fairwaves, Inc. https://fairwaves.co 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 The wiki is quite outdated, and no USRP related man page was ever created.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 ----- Eredeti üzenet ----- Feladó: "OMAR RAMADAN" <omar.ramadan at berkeley.edu> Címzett: openbsc at lists.osmocom.org Elküldött üzenetek: Péntek, 2015. Július 24. 20:12:28 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
