Hello Alexander: Which version of UHD are you using?? Are you using Transceiver52M ?? Jumping ahead to some of your more-recent posts, you should not necessarily need a GPSDO, but you might very well benefit from having one. Have you looked on a spectrum analyzer to make sure that the signal is being transmitted on the correct ARFCN, and to see how much frequency error there is? --Neel On 29 February 2016 at 09:03, Alexander Schmidt < ale...@ya...> wrote: > Hello, > > I have an USRP B200 with 2 Vert900 antennas here. > I got OpenBTS 5.0 up and running and smqueue, sipauthserve and asterisk as > well. > The OpenBTS transceiver is somehow not working, so I installed osmo-trx, > and software-wise it seems to work, but 2 issues remain: > > - red LED at the transceiver, when I start services, blinking from time to > time > - no network visible (scanning for network with Iphone 4S and Motorola > C118) > > I use these commands to get it running: > > sudo stop asterisk > sudo stop sipauthserve > sudo stop smqueue > sudo stop openbts > > sudo osmo-trx -f > sudo asterisk -vvvr > sudo sipauthserve > sudo smqueue > sudo start openbts > sudo /OpenBTS/OpenBTSCLI > > As soon as I start the openbts service with sudo start openbts, the > transceiver osmo-trx immediatly starts working and gives me that kind of > output: > > .. > NOTICE 3020118848 17:59:58.8 Transceiver.cpp:404:pushRadioVector: dumping > STALE burst in TRX->USRP interface > .. > > Where did I go wrong? > Will be very thankful for any advice! > > Best regards, > Alex > > > ------------------------------------------------------------------------------ > Site24x7 APM Insight: Get Deep Visibility into Application Performance > APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month > Monitor end-to-end web transactions and take corrective actions now > Troubleshoot faster and improve end-user experience.
