scope of scheduler.c and trx_sched_*
by Neels Hofmeyr 30 Jun '16

30 Jun '16

I notice that apparently osmo-bts-trx is the only caller of the trx_sched_* API, yet it is implemented in common/scheduler.c and compiled to libl1sched.a. Is osmo-bts-trx really the only caller? Also in osmo-bts-trx, the "trx" to me means SDR, like B200. But any BTS has one or more TRXs. So why isn't it osmo-bts-sdr? That's why I thought: maybe trx_sched_ is for all BTS models? Thanks for any clarification / confirmation :) ~Neels -- - Neels Hofmeyr <nhofmeyr(a)sysmocom.de> http://www.sysmocom.de/ ======================================================================= * sysmocom - systems for mobile communications GmbH * Alt-Moabit 93 * 10559 Berlin, Germany * Sitz / Registered office: Berlin, HRB 134158 B * Geschäftsführer / Managing Directors: Harald Welte

osmotrx init problem
by Max 29 Jun '16

29 Jun '16

Hi. I've got following problem while trying to make osmotrx work in multitrx setting on USRP B210: sudo chrt 20 ./Transceiver52M/osmo-trx -c 2 sudo chrt 15 ./src/osmo-bts-trx/osmo-bts-trx -t 2 -c ~/.config/osmocom/osmo-bts-mtrx.cfg -d DRTP:DCC:DRSL:DOML:DL1C:DTRX The bts quits from trx_if.c after checking "if (tcm->critical) {...". The command sequence seems to be the same for both phy0.0 and phy0.1 However 0.0 one accepts SETTSC command and 0.1 rejects it: trx_if.c:380 transceiver (phy0.1) rejected TRX command with response: 'RSP SETTSC 1 7' So far I fail to see where this difference comes from.

openBSC paging issue
by robert 28 Jun '16

28 Jun '16

Hi, when trying to work with multiple BTS as noted in http://umtrx.org/multi-bts-with-osmocom-and-a-single-umtrx/ , I faced a problem related to paging. When I start the BTS, I can send SMS to any connected phone but after a few minutes no SMS is sent and I can’t even make calls. I noticed that the target phone is not being paged anymore. If I restart the openBSC instance the old pending messages get sent sometimes. Also if I run the same code but with only one OSMO-BTS instance, everything works fine. I would really appreciate some help. Best regards,

iphone backdoor?
by Max 22 Jun '16

22 Jun '16

Hi. While testing I've got iphone (non-jailbroken) which regularly attempts to send following sms to number 447537410247 (uk?): REG-REQ?v=3;t=C335D183C5A2FC0E2501543EBCEB8263D55683FB63A2E8CAF98B8874D940263F;r=165209558 without asking user for anything. Is this some sort of Apple's backdoor? Or GCHQ is so bored that they are trying to spy on me? :) Have you guys seen this before? -- Max Suraev <msuraev(a)sysmocom.de> http://www.sysmocom.de/ ======================================================================= * sysmocom - systems for mobile communications GmbH * Alt-Moabit 93 * 10559 Berlin, Germany * Sitz / Registered office: Berlin, HRB 134158 B * Geschaeftsfuehrer / Managing Director: Harald Welte

Hi. I've noticed check for device type around Transceiver52M/UHDDevice.cpp:772 - seems like USRP B200 is not supported for multitrx configurations: sudo chrt 20 ./Transceiver52M/osmo-trx -c 2 sudo chrt 15 ./src/osmo-bts-trx/osmo-bts-trx -c ~/.config/osmocom/osmo-bts-trx.cfg -i 192.168.122.1 -t 2 Where does this limitation comes from? Is it just smth which is not implemented (yet) or it's impossible to implement due to X and Y? -- Max Suraev <msuraev(a)sysmocom.de> http://www.sysmocom.de/ ======================================================================= * sysmocom - systems for mobile communications GmbH * Alt-Moabit 93 * 10559 Berlin, Germany * Sitz / Registered office: Berlin, HRB 134158 B * Geschaeftsfuehrer / Managing Director: Harald Welte

I don't remember the code exactly, but IIRC this is equivalent to setting or removing 'tsc' line in the config file. Please excuse typos.

So, it appears we should add litecell15 to our osmo-bts build? We didn't catch my breaking it with the gsm_chan_t_names change. ~Neels
