SIMtrace v2.0
=============

This is the repository for the next-generation SIMtrace devices,
providing abilities to trace the communication between (U)SIM card and
phone, remote (U)SIM card forward, (U)SIM man-in-the-middle, and more.

NOTE: Nothing in this repository applies to the SIMtrace v1.x hardware
or its associated firmware.  SIMtrace v1.x is based on a different CPU /
microcontroller architecture and uses a completely different software
stack and host software.

This Repository
---------------

This repository contains several directory

* firmware - the firmware to run on the actual devices
* hardware - some information related to the hardware
* host - Programs to use on the USB host to interface with the hardware


The host software includes

* libosmo-simtrace2 - a shared library to talk to devices running the simtrace2 firmware
* simtrace2-list - list any USB-attached devices running simtrace2 firmware
* simtrace2-sniff - interface the 'trace' firmware to obtain card protocol traces
* simtrace2-cardem-pcsc - interface the 'cardem' fimrware to use a SIM in a PC/SC reader
