Hi,

> (bts=0,trx=0,ts=1,ss=0)

Why SMS transmission is on TS1?
Which channel configuration do you use?

With best regards,
Vadim Yanitskiy.

OK,

I tried Ubuntu 14.04 amd64 and Segmantation error disappeared. I can connect to my network, register subscribers, perform USSD but now I cannot receive SMS. 
In NITB logs I can see an error. <0022> gsm0411_smc.c:331 SMC(0) cannot release yet current state: WAIT_CP_ACK

Don't you know what can it mean?

OK,

I reassembled all the files with "old" toolchain and now I can see network but when I try to do a location update or add subscriver manually I get

Segmentation fault (core dumped)

In syslog:
May 10 15:08:33 osmobox kernel: [  740.703083] osmo-nitb[2517]: segfault at 6e656d70 ip b778b589 sp bf84ba40 error 4 in libdbdsqlite3.so[b7788000+8000]


It seems there is some issue with HLR's sqlite.
Did you meet such error before?

I found also this thread

Should I use x64 bit architexture to solve it? Do you have working setup of calypsoBTS? What OS do you use for that?

Kind regards.

Hello again,

I set up bts like sysmobts but it seems there are some other issues.
If I understood it correct I must specify phys_channel_confif for all TS of the BTS.
Otherwise OsmoBTS cannot get settings from OsmoBSC. What config should I set for TS2-TS7?
And will "slotmask 1 1 0 0 0 0 0 0" affect somehow the OsmoBTS behaviour?

Now I can find my networks (sometimes :) but when my phone found it OsmoBTS crashes with the following message...:

<0006> scheduler.c:1506 Set a5/0 uplink for SACCH/4(0) on trx=0 ts=0

Hi Vadim!

Thank you for the comments. I will check your advices. Actually I already watched everything on youtube and other resources☺ But it needs more time to perceive all the info correctly...

Yeah, still couldn't find some time to update the wiki.

Why do you think so? No, CalypsoBTS has nothing related
toip.access nanoBTS. From the other side, we don't have
a dedicated type for OsmoBTS, so you can use 'sysmoBTS'.

Please watch a great Sylvain's talk, where he explained
almost everything you need to know:

"Further hacks on the Calypso platform"
https://media.ccc.de/v/29c3-5226-en-further_hacks_calypso_h264

In short: BTS should transmit a continuous beacon on C0 to be
detected. Normal MS can't do that. CalypsoBTS was hacked to
perform the following timeslot layout: Tt_R_ttt, where
'T' means TX on Downlink, 'R' means RX on Uplink, and 't' means
channel filling - dummy bursts. Phone cannot RX and TX at the
same time, so one phone serves only one TS. With two phones
you have the following layout: TT_RRttt, so you have two
timeslots served.

This is why you will have some detection troubles even with
working BSS setup :/

Just delete the 'settsc' line from your config, because CalypsoBTS
transceiver only supports 'setbsic'.

Have a fun!
