USB commands
by Samuel Weinbeck 20 Feb '13

20 Feb '13

Hi all, I am playing around with the USB commands in SIMTrace but I'm having a bit of trouble. I wrote a short python script to send a GET_VERSION command. However, only the first one is received by the board. If I run it, the first time I will see a GET_VERSION in the debug terminal. If I try again, however many times, I do not see any output. Why is this? The script: ---snip--- #!/usr/bin/python import usb.core import usb.util cmd="\x01\x00\x00\x00" dev=usb.core.find(idVendor=0x16c0, idProduct=0x0762) dev.set_configuration() dev.write(1, cmd, 0) ---snip---

Initialization log
by Hugo Soares 07 Feb '13

07 Feb '13

Hi guys, My group bought a SIMTrace board from you and we're waiting for it to arrive. In the meantime, would you mind sending a log collected with it? Log should have the initial communication (including ATR) until network registration. Is that too much trouble? -- Atenciosamente, Hugo Frederico Soares

PLL
by Samuel Weinbeck 31 Jan '13

31 Jan '13

I'm wondering if the SIMTRACE board can be made to operate faster with the PLL provided by the Atmel microcontroller. I'm looking around in src/start/Cstartup_SAM7.c but I'm a bit confused by the values. The Atmel PLL filter calculator doesn't allow dividing by 24 and multiplying by 125 with Fin=18.432MHz, R1=1000, C1=10nF, C2=1nF.

Dear all, I'm traying to snoop a samsung galaxy s3, but I've noticed this mobile has usim and it is uncompatible withe the PCB SIM adapter. Is there a PCB usim adapter or another kind of adapter permitting connect the SIMtrace device? Thanks in advance!!!! ;) Roger Jardí Personal de Suport a la Recerca Grup de recerca CRISES Departament d'Enginyeria Informàtica i Matemàtiques Universitat Rovira i Virgili Despatx 132 Av.

sim emulation
by "Roger Jardi Cedó" 11 Dec '12

Dear all, I'am asking how can I emulate a sim/smartcard with my SIMtrace. Could you say to me if I need an extra software or change any jumper etc? I have not found no documentation about that... Thank you very much. Roger Jardí Personal de Suport a la Recerca Grup de recerca CRISES Departament d'Enginyeria Informàtica i Matemàtiques Universitat Rovira i Virgili Despatx 132 Av.

T=0 and T=1 sniffer
by "Roger Jardi Cedó" 21 Nov '12

21 Nov '12

Dear all, I'am new in this mailing list. I'am a PhD. student at the University Rovira i Virgili studying smart cards (SC). I would like to log transmitted apdus between reader and SC (like credit card, ID card, sim, etc). I've recently bought a cheap sniffer (season interface) but I have problems with it, I lose data sniffing any smart card type (iso-7816). I'm asking if your device (v1.1) is valid for this purpose. Note that v2 would be compatible with credit card sized smart cards (ID-1 and ID-000 smart card slots (with presence detection): so to be able to also sniff credit card sized smart cards). However, I've read too that v1.1 is capable to read smart card with both modes (T=0 and T=1) with proper accessories (http://shop.sysmocom.de/products/fullsize-sim-fpc and http://shop.sysmocom.de/products/sim-adapter). It is possible? With this device, I will log any smart card type?

actually the error is 98 62 which is invalid mac. i have checked tha apdu and it is correct (as the 31.102 describes). the MAC as i read is produced y the f1. MAC = f1_K (SQN || RAND || AMF) i think that the SQN i import is the problem then On 11/19/2012 01:00 PM, simtrace-request(a)lists.osmocom.org wrote: > Send simtrace mailing list submissions to > simtrace(a)lists.osmocom.org > > To subscribe or unsubscribe via the World Wide Web, visit > https://lists.osmocom.org/mailman/listinfo/simtrace > or, via email, send a message with subject or body 'help' to > simtrace-request(a)lists.osmocom.org > > You can reach the person managing the list at > simtrace-owner(a)lists.osmocom.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of simtrace digest..." > > > Today's Topics: > > 1.
