Pysim error: SW match failed
by Martin Nagy 16 Aug '25

16 Aug '25

Hi all, After buying a super Sim Kit (16 in 1) from China, I tried the reader (green PCB inside a blue transparent plastic case with a blue LED) and SIM (identified as a fakesupersim) with pysim tool. However i am getting the following error: /pySim-prog.py -n 26C3 -c 49 -x 262 -y 42 -z 1234 -j 1 -t auto Insert card now (or CTRL-C to cancel) Autodetected card type fakemagicsim Generated card parameters : > Name : 26C3 > SMSP : e1ffffffffffffffffffffffff058100945555ffffffffffff000000 > ICCID : 8949262427518313026 > MCC/MNC : 262/42 > IMSI : 262422461512085 > Ki : 7b74741a1ee14337ec23f9ab92a13648 > OPC : ccd867d60797d8d45354a51b3ef568ff Programming ...

Also I have tried forcing different models of SIM, but nothing is working. Obviously I can remove this check from the script file (__init__.py in /pySim/transport), however somebody had a reason to put such condition there. I would like to ask if it is safe to remove that line of code and the purpose of that line of code. Thanks a lot and best regards Martin

Re: Help with sccp library

I means: is the interaction with mtp3 layer implemented (is sending sccp data by mtp3 implemented by the library?)? Also, what about the reception of data from mtp3 layer. is that implemented in the sccp lib. I am asking these questions because I see the code of mtp3 in the lib but no significant call is present in the sccp part of the lib. Thank you for your help.

Hard reset NanoBTS after forgetting static IP
by Luca Bongiorni 22 Nov '13

22 Nov '13

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hey there, I have come across a nanoBTS 165AU but since is used and not tested from the previous owner, I guess it has set a static IP. After turned on is booting (RED light) and then remains (ORANGE not flashing) even if the eth is connected to the router. At the moment I am trying with ipaccess-find and BtsInstaller to find in on my LAN . Unfortunately it is not answering and is not even getting an IP from the router by the DHCP daemon. Two possibilities, I have thought: - - an hw/sw issue; - - a Static IP is set. Supposing that is the 2nd possibility, I was thinking: - - to change private class of my LAN, to see if it changes something; - - to make an hard reset of the bts. Do you know if it possible to reset in someway? Ever happened this issue to you guys? Suggestions or insults are welcome. Thanks in advance. Cheers, Luca P.S.: I don't recall exactly, but one time I heard that is possible to reset by short-circuiting some pins of the LAN/48VDC eth connector. Is it right?! -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.17 (Darwin) Comment: GPGTools - http://gpgtools.org iQIcBAEBAgAGBQJSE682AAoJEPLE1Qsi6ZiTuKkQAJaYGFTgMF5XlWuZuCI1eSvU lVCvpdB+fDRY7o6iut3y0fGlS1ZOIS8X93c7/T0XKUvSJaZ2ARIGjqi81A4XlkAK pdFvBNPKixYATYZYhP3nIggC1QGK9fuWQSUKVEGgnswsXt0VaJKdEwgn0CX7ttku uoh6FM3vtp30drB4t9oe0bW9M9qzGz6yyw+8asaqQBs8bafOHm4+S4kJsN6lYmPU wY/s8ctzqZerNI0MwBVASZCFldsyWe0NuduquYZlwg4god996srFNkVQL+o9nrmF vmPb896DTsCdivwqs+UyaZOgp1mKxjtfco275pVATG4qSAgz/JYQBxWK6fWQr+Zv PIzQvFLME1kh/29nUihxw93mzju5Rz1naTosx5+Fs7jPjCFocqD5Var3hkU4iu78 kNALJNx6UGOdfbqcInO30ltSm21HH1QBJnIoZf6MblELvHcvHbBNyPB8zM13suoS y3/oD/wcXefQaMaSa5HFc30ydJHBWS+adNlVp3fdYYArZaVkFxaVjJx8fW1juPVx 54aco5j7/tZD5tfg9FCOTHqmAiOVDqjs7nZrOpsRdkdPJHq2uHbGmHGqyhZlVWNv B+9/eiOdQyKZ5R+3vvRrmhBe9g2a28xtRI7N8KxwCov0wbA6R0h8l2UtGza6NTcn EUdW3ptIWP216tSFdVTs =9Ctc -----END PGP SIGNATURE-----

Re: OpenBSC + USSD Application

Hi Harald (sorry for the typo). I think that line 10 is a log of the USSD call I made. My configuration is: - Followed the tutorial. ( http://openbsc.osmocom.org/trac/wiki/network_from_scratch (using all configurations shown in the tutoria, except the network name, that I changed to DCG). - Using a Ettus USRP N210 - All libraries installed in my notebook, with Ubuntu 13.04 kernel 3.8.0-29-generic. - Starting osmo-nitb with the following command: osmo-nitb -c ~/.osmocom/open-bsc.cfg -l ~/.osmocom/hlr.sqlite3 -P -m -C --debug=DRLL:DCC:DMM:DRR:DRSL:DNM - I manually select the network in the Network Preferences. The phone is an old Motorola Z6. Hope it helps. If you need more information, just ask. If you need, I can use other configurations or command options.

OpenBSC with A-interface
by Dmitri Soloviev 07 Sep '13

07 Sep '13

Hi list, Peter, thank you for your reply. I still have questions about media control: 1) when parsing MGCP CRCX, sdp is not expected. May I change it? 2) I still can't run media in BSC mode. Seems I'm missing something. osmo-bsc and osmo-bsc_mgcp are running BSSAP works perfectly But it seems two interfaces are working completely independent: -- MGCP between MSC and BSC -- interface between BSC and BTS (ip.access): at MGCP, connection is acknowledged, endpoint is allocated (at BSC ip=192.168.1.11) at ip.access interface between BSC and BTS, BTS replies to ip.accessCRCX with proper acknowledgement with proper ip:port at BTS (192.168.1.9) , then BSC issues ip.accessMDCX with endpoint ip zero: 7e:73:01:09:f8:00:2d:*f0:00:00:00:00*:f1:0f:be:f4:00:f2:03 My attempts to modify connection at MGCP interface has no impact on ip.access interface The key question, I'm not getting how osmo-bsc and osmo0bsc_mgcp are interacting.

[PATCH 1/6] vty: Fix BSC_NODE prompt string
by Jacob Erlbeck 02 Sep '13

02 Sep '13

Change '%s(bsc)#' to '%s(config-bsc)# '. The missing trailing blank brakes osmopy's VTYInteract.command() because the blank is contained in the end patterns which are checked to decide whether to leave the select loop. Thus trying to execute the 'bsc' command there blocks the test script forever. --- openbsc/src/osmo-bsc/osmo_bsc_vty.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/openbsc/src/osmo-bsc/osmo_bsc_vty.c b/openbsc/src/osmo-bsc/osmo_bsc_vty.c index 8eaa55b..f6cf1a0 100644 --- a/openbsc/src/osmo-bsc/osmo_bsc_vty.c +++ b/openbsc/src/osmo-bsc/osmo_bsc_vty.c @@ -43,7 +43,7 @@ static struct osmo_msc_data *osmo_msc_data(struct vty *vty) static struct cmd_node bsc_node = { BSC_NODE, - "%s(bsc)#", + "%s(config-bsc)# ", 1, }; -- 1.7.9.5

SMPP Submit_SM sender address
by Alexander Chemeris 29 Aug '13

29 Aug '13

Hi Harald, We're trying out SMPP interconnection and found that for Submit_SM (aka MT-SMS) sender is always set to an extension of subscriber ID 1. Looking into the code, this happens because we set "sms->sender" to point to subscriber ID 1 in submit_to_sms() function in SMPP code: /* fill in the source address */ sms->sender = subscr_get_by_id(net, 1); sms->src.ton = submit->source_addr_ton; sms->src.npi = submit->source_addr_npi; strncpy(sms->src.addr, (char *)submit->source_addr, sizeof(sms->src.addr)-1); And then src.addr/ton/npi are ignored when we store to the SMS DB and only subscriber ID is stored: /* FIXME: correct validity period */ result = dbi_conn_queryf(conn, "INSERT INTO SMS " "(created, sender_id, receiver_id, valid_until, " "reply_path_req, status_rep_req, protocol_id, " "data_coding_scheme, ud_hdr_ind, dest_addr, " "user_data, text) VALUES " "(datetime('now'), %llu, %llu, %u, " "%u, %u, %u, %u, %u, %s, %s, %s)", sms->sender->id, sms->receiver ? sms->receiver->id : 0, validity_timestamp, sms->reply_path_req, sms->status_rep_req, sms->protocol_id, sms->data_coding_scheme, sms->ud_hdr_ind, q_daddr, q_udata, q_text); So when we read SMS back from the DB, sender address is taken from that subscriber. It seems that a solution is to store actual ton/npi/addr in the SMS DB instead of storing ID. Then we could set sms->sender to NULL and just ignore it. Is there anything wrong with this approach? Otherwise we'll work on a patch to implement that. PS What is the current policy about changing DB layouts - just increase SCHEMA_REVISION? -- Regards, Alexander Chemeris.
