Fix missing generation of waiting-time-extension in some situations

In the function set_tpdu_state(), there is a missing transition to
WAIT_TX state. This is fine if you are coming from the WAIT_PB state,
which has already restarted the waiting timer via
card_emu_uart_update_wt(), but if you are coming from the WAIT_RX
state, then card_emu_uart_update_wt() is never called and the USART
timer is never restarted.  (Because the transmitter is left enabled in
WAIT_RX, the response is still sent to the modem; it is just the
half-wait timeouts that are missing).

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
