Osmocom SIMtrace 2 is a software, firmware and hardware system for passively tracing SIM-ME communication between the SIM card and the mobile phone, and remote SIM operation.
6 9 tsaitgaist
While it was designed for SIM-ME communication, it supports all ISO 7816 smart-cards using the T=0 protocol (the most common case).
7 1 tsaitgaist

It is a followup of the "SIMtrace project":/projects/simtrace/wiki, providing more functionalities (e.g. remote SIM operation) and supporting multiple boards (e.g. SIMtrace with SAM3S, "sysmoQMOD":https://www.sysmocom.de/products/sysmoqmod/index.html).

h2. Hardware
11
12 10 tsaitgaist
The SIMtrace 2 firmware supports several boards.
13
The firmware is written for an "ATSAM3S4B":https://www.microchip.com/wwwproducts/en/ATSAM3S4B micro-controller.
14 1 tsaitgaist
15 12 tsaitgaist
Note: The SAM3S is meanwhile labelled as _not recommended for new designs_ by Atmel. However, there are plenty of hardware and software compatible upgrade options, including SAM4S. The upgrade is possible in the future.

The main purpose of this board is to sniff the communication between a phone and a SIM card (or any card reader and smart-card).
22 1 tsaitgaist
23 17 roh
This is the same circuit board as the previous "SIMtrace v1":/projects/simtrace/wiki/SIMtrace_Hardware, with the exception that the "ATSAM3S4B":https://www.microchip.com/wwwproducts/en/ATSAM3S4B micro-controller replaces the old "AT91SAM7S64":https://www.microchip.com/wwwproducts/en/AT91SAM7S64. Since the SAM3S is pin compatible with the SAM7S, any SIMtrace v1 board can be converted into a SIMtrace v2 board simply by replacing the micro-controller.

This is a carrier board for cellular modems in ngff / M.2 form-factor with on-board simtrace2.  It is wired in a way that it can operate both as passive tracer/sniffer, or in @cardem@ mode.

h2. Firmware
59
60 10 tsaitgaist
The SIMtrace 2 firmware source code is available in "git":https://git.osmocom.org/simtrace2/.
61 20 tsaitgaist
Pre-built firmware binaries are available "here":http://ftp.osmocom.org/binaries/simtrace2/firmware/.
62
The firmware are currently under active development and we recommend to [[Flashing|flash]] the new firmware images to profit from the latest bug fixes and added functionalities.
63 1 tsaitgaist
64
The SIMtrace 2 firmware is a complete rewrite and *can only be flashed on hardware with SAM3S* ARM Cortex-M3-based micro-controllers.
65 18 roh
*The SIMtrace 2 firmware is not compatible with the older "SIMtrace v1":/projects/simtrace/wiki/SIMtrace_Hardware using SAM7S ARM7TDMI-based micro-controllers.*

To get the version of the firmware flashed on the device, you can use the @simtrace2-list@ tool

h3. trace
70 1 tsaitgaist
71 12 tsaitgaist
The trace application firmware allow to sniff the communication between a phone and a SIM card (or any card reader and smart-card).
72
It is intended for the [[Wiki#SIMtrace v2|SIMtrace v2 hardware]] and its function is analog to the "SIMtrace v1":/projects/simtrace/wiki/SIMtrace_Firmware.
73 10 tsaitgaist
74 12 tsaitgaist
The sniffing is completely passive. It uses the RST, ATR, PPS (baud rate tested with F/D up to 512/32), and WT (waiting timeout) to properly parse the ISO 7816-3 TPDUs.
75
Currently only the T=0 protocol is supported since this is the most common protocol used (we haven't seen T=1 in use).

h3. card emulation
82
83 25 tsaitgaist
The card emulation application firmware allows to emulate a card (e.g SIM). This is useful if you don't want to change the card in the device (e.g. phone), or have the card in a remote location.
84 24 tsaitgaist
85
This firmware comes preflashed on the sysmoQMOD board.

150
151
h4. simtrace2-list
152
153
@simtrace2-list@ allows to list all SIMtrace 2 compatible devices:

161
162
h4. simtrace2-sniff
163
164
This will use the [[Wiki#trace|trace]] firmware and retrieve the sniffed phone-SIM communication.
165
The activity will be shown on the consol output:
