SIMtrace 3FF / micro-SIM adapter available
by Harald Welte 18 Oct '13

18 Oct '13

Hi! I really don't want to feel this list to be abused for advertisements, but in this case I'm sure it is of actual help to a number of people on this list: The sysmocom web shop finally has a 3FF (micro-SIM) adapter cable available: http://shop.sysmocom.de/products/simtrace-fpc-3ff Please note that (as opposed to the regular mini-SIM) we only have one of the possible four orientations available. This is primarily due to the high manufacturing cost of low-volume flexible PCB projects. We would like to hear from you 1) if you need this adapter in different orientation (which, for which phone) 2) for which phone model you have used this new 3FF adapter successfully 3) what kind of problems you may have encountered using it. Thanks to Kevin Redon for doing the PCB layout of this part. It is freely available as part of the simtrace.git repository since commit eee3243ddaa9e13bc7509a962fade8636b6ed2ab. On a related note: For nanoSIM, I think we would have to go for dual-layer PCB with vias placed inside the actual card contact pads. This will make production cost even more expensive than the microSIM adapter. So unless there's significant interest in a nanoSIM adapter, it's unlikely that we'd have some made. Please let us know if you absolutely want one, and if you're happy to pay even more (e.g. 25-30 EUR) for only that adapter.

SIMtrace MITM/emulator
by Tom Schouten 16 Aug '13

16 Aug '13

Hi List, What is the current status of the MITM support? Anyone working on it behind the scenes? Also, I'd like to gauge how much work would be necessary to implement an emulator mode, with emulator running on PC. I.e. SIMtrace used to doe ATR handshake and then hand over all APDU to host PC over USB. Cheers Tom

SIMtrace phone-side VCC
by Tom Schouten 30 Jul '13

30 Jul '13

Hi folks, Seems not all phones use 3V signaling if the PHONE-side VCC pin is tied to 3V. This one insists on 1.8V : BLU SAMBA JR PLUS Is this trick of tying VCC to 3V standard behavior? For future version of the board, it might be interesting to tie the VCC pin to an ADC input, to detect different voltage levels so the firmware can wait until phone decides to use 3V. Cheers Tom

ask about design sim card reader
by anak galer 25 Jul '13

hello , anyone have schematic design sim reader PC/SC , yesterday i'm make some reader but not support with PC/SC apps in here (http://git.osmocom.org/osmo-sim-auth | A smart card reader compatible with pcsc-lite) i think my card support with phoenix reader? and anyone can explain the differences between the PC / SC with phoenix sim reader or etc Regards

Fwd: Cellphone can't detect sim card
by Tali Budur 24 Jul '13

24 Jul '13

Hi! I have built 2 units of simtrace hardware recently. All the components came from digikey, I used the bom list from git. The PCBs are electrically tested. When I connected it to the pc, simtrace application can communicate with the device and I can debug it via the FTDI connection. The problem is, when I connect it to a cellphone, cellphone can not detect a sim card. Simtrace can detect vcc on, vcc off and rst signals from the cellphone however, cellphone can not detect the sim card. I used several different cell phones and sim cards. I also checked the connection between the cellhpone and simtrace. Couldn't find a problem. May I kindly request your help to solve the problem? Thanks,

hi guys I have a problem with the simtrace, when I restart the smartphone some APDU are smaller than 8 bits, this is a know issue? Francisco Marinho

SIM tracer for Saleae Logic
by Tom Schouten 10 Jul '13

10 Jul '13

Hi List, This might be of interest to folks here. A couple of days ago I found out the Saleae Logichas an SDK that allows you to live stream raw sample data straight into a C++ application. Quite neat, as it can go to fairly high sample rates. Here is a proof of concept version of a live APDU protocol sniffer using the SL: https://github.com/zwizwa/sl-apdu Essentially it's just a UART state machine with some hardcoded ATR parsing (for the specific SIM card I have) which calls into apdu_split from git://git.osmocom.org/simtrace.git after the ATR handshake. I had a look at the ISO7816 parser in the SIMtrace firmware, but it's fairly tied to the hardware. With some refactoring it's probably easy to reuse. ( The sl-apdu repo has a first attempt to a dirty stub approach to run the original AT91 code. Probably not be the way to go.. ) Cheers Tom
