Dear team,
I did set up GSM network with SDR (LimeSDRmini).
SMS are ok.
However when try to make voice call got following message on osmo-bsc terminal:
<0003> abis_rsl.c:1372 (bts=0) CHAN RQD: reason: call re-establishment (ra=0x41, neci=0x01, chreq_reason=0x02)

<0016> input/ipaccess.c:411 Bad signalling message, sign_link returned error: Operation not permitted.
<0016> input/ipaccess.c:411 Bad signalling message, sign_link returned error: Operation not permitted.
WHat is this bad signalling message operation not permitted?

Dear baseband-developers team,
Would you be so kind to advise me on the following:
I desire (dramatically want very much) to learn / understand Osmocom projects.
I am a beginner in programming and i try to understand / learn C files that the project is build of.
As an example i tried to learn / understand for example an Osmocom message buffer — msgb.h file.
But immediately faced some syntax difficulties:
This is the extract of msgb.h file:
struct msgb {
struct llist_head list; /*!< \brief linked list header */
/* Part of which TRX logical channel we were received / transmitted */
/* FIXME: move them into the control buffer */
union {
void *dst; /*!< \brief reference of origin/destination */
struct gsm_bts_trx *trx;
};
As it can be seen a structure «msgb» has as one of its components another structure — «gsm_bts_trx»
But in whole Osmocom BB project files i could not find definition / description of struct «gsm_bts_trx».
Would you kindly advise me please how to see which components / constituents / elements are in this gsm_bts_trx structure?
From which components is struct gsm_bts_trx build of?
Thank you so much for your kind advise.

Dear all,
I am using LimeSDRmini to run osmo-bts…
During operation from time-to time (and sometimes quite frequently) following messages pop-up in terminal:
«Dropped packets by HW!» and «Dumping Stale bursts...»
I guess my LimeSDRmini is dropping some packets.
LimeSDRmini configuration is: Firmware 6, Hardware 3, Protocol1, Gateware 1.3.
Would you advise — may be there is more or less stable firmware version that to some extent is stable while working with Osmo-bts ?
Thanks

Dear baseband developers team,
I built home gsm network with Osmo-stp-msc-hlr-bsc-bts, osmo-trx limeSDR.
I managed and registered phones. I did send sms between each other.
However when i decided to make a call — i noticed following message in terminal: «PCU socket not connected, dropping message».
I searched on Osmocom web site and it is said that pcu socket is involved in GPRS things (i.e. in internet).
Therefore why does such message appears when i try to make simple call between two mobiles — it has nothing to do with GPRS…
And what would you advise me how to resolve this ?
P.S. initially when i was about to start osmo-bts-trx i got message «PCU L1 socket failed» and i just renamed the pcu_bts file to some other name and osmo-bts-trx started.
Thank you so much for your kind reply.
Best regards

Dear all,
Pls help me with the following issue: I want to run a transceiver having motorola c115…
i follow the procedure described in CalypsoBTS page : http://osmocom.org/projects/baseband/wiki/CalypsoBTS
without chainloader i get:

got 7 bytes from modem, data looks like: 66 74 6d 74 6f 6f 6c ftmtool
Received FTMTOOL from phone, ramloader has aborted
got 1 bytes from modem, data looks like: 65 e
got 1 bytes from modem, data looks like: c1 .
got 1 bytes from modem, data looks like: 66 f
and with chainloader i get:
