Instead of using the timer/counter peripheral to handle the waiting time and corresponding timeout, the USART peripheral internal timeout mechanism is used. This is particularly important for the SIMtrace board since there (contrary to other boards) the I/O signal is not wired to a TIO pin of the timer/counter block, and hence Rx/Tx data cannot reset that timer/counter. As a result of this migration, cardem is now supported not only on owhw + qmod, but also on the simtrace board. The guts of this change have been lifted out of Change-Id Ibcb2c8cace9137695adf5fb3de43566f7cfb93b5 by Kevin Redon, which was unfortunately touching various different topics at the same time and hence was split up. Some improvements are the introduction of the ENABLE_TX_TIMER_ONLY mode, which avoids the USART interrupt handler getting hammered with TXRDY between release of RST and start of the ATR.

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.
Supported Hardware
- Osmocom SIMtrace 1.x with SAM3 controller ** this is open hardware and schematics / PCB design is published
- sysmocom sysmoQMOD (with 4 Modems, 4 SIM slots and 2 SAM3) ** this is a proprietary device, publicly available from sysmocom
- sysmocom OWHW (with 2 Modems and 1 SAM3 onboard) ** this is not publicly available hardware, but still supported
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
