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.

• Osmocom SIMtrace2 with SAM3 controller
  • this is open hardware and schematics / PCB design is published
  • pre-built hardware available from sysmocom webshop
• Osmocom ngff-cardem M.2/NGFF modem carrier with SAM3 controller
  • this is open hardware and schematics / PCB design is published
  • pre-built hardware available from sysmocom webshoo
• sysmocom sysmoQMOD (with 4 Modems, 4 SIM slots and 2 SAM3)
  • this is a proprietary device, publicly available from sysmocom
  • hardware evaluation kit available from sysmocom webshop
• sysmocom OWHW (with 2 Modems and 1 SAM3 onboard)
  • this is not publicly available hardware, but still supported

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
