Incomplete trace (due to high-speed SIM?)

I am guessing it's the req_ctx.c / req_ctx.h? Thanks

SIMtrace 3FF / micro-SIM adapter available
by Harald Welte 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.

iPhone Terminal Profile
by Matt S 19 Sep '13

Does anyone have a Terminal Profile handy for an iPhone 4 or 4S? I dont' have the microSIM SimTrace adapter, and the database here: https://terminal-profile.osmocom.org/ doesn't appear to have been updated in a while. Thanks!

MITM voltage fix using ATR
by Tom Schouten 10 Sep '13

10 Sep '13

Hi List, When using MITM it is possible to set the SIMtrace<->phone voltage levels using ATR, giving a clear-cut way to solve the incorrect I/O level problem: See byte TA(3) C7->C2 orig ATR from card: http://smartcard-atr.appspot.com/parse?ATR=3B9F95801FC78031E073FE2113574A33… modded to select only 3V: http://smartcard-atr.appspot.com/parse?ATR=3B9F95801FC28031E073FE2113574A33… Cheers, Tom

INS=STATUS + car reset question
by Tom Schouten 04 Sep '13

04 Sep '13

Hi List, I'm running into the following command sequence in a Nexus One Android 2.3 phone: C-APDU:80F20001FF (STATUS) R-APDU:6C12 (Incorrect Parameter P3) After which the phone power-cycles the card. I'm wondering whether this is is desired behavior, or if it's a bug in the new MITM code. Phone seems to reset the card quite often when in USIM mode. Running the card in SIM mode, this doesn't happen. Cheers Tom
