SIM card related Projects » SIMtrace 2

Hi,

I’m involved in a project with RSP SIMs where we need to get insight in the communication between modem and SIM.
So I bought a SIMtrace V2 board (from Sysmocom) and worked on my hardware setup based on: Ubuntu 18.04.4 LTS (GNU/Linux 5.3.0-45-generic x86_64).
Although I have some experience with Linux during my study, it is quite rusty, but as far as I’m aware my installation is completely up to the latest versions of everything.
I have followed the steps from the Wiki to build and install and that didn’t cause any errors, but in the end it doesn’t look right, there is no output.

I have tried to verify everything what I have done so far, but it doesn’t help, see below.

Firmware seems to be ok based on the response of DFU tool:
hugo@hugo-ubuntu:~$ sudo dfu-util --list
[sudo] wachtwoord voor hugo:
dfu-util 0.9

Two USB ports are available, the first one connected to the board:
hugo@hugo-ubuntu:~/simtrace2/host/src$ sudo ./simtrace2-list
USB matches: 2

The sniffer shows no data what so ever:

Entering main loop

There is no output, requesting SIM data via Quectel dev board doesn’t change that. Also in Wireshark nothing is happening

Pressing the reset button on the board causes this error to appear:
BULK IN transfer error; rc=-4

I have used a Quectel development board with AT commands to see if any SIM related info is getting through, but is seems that there is no transparent communication with the SIM:
[2020-04-03 15:34:33:517_R:] AT+CPIN?
[2020-04-03 15:34:33:517_R:] +CME ERROR: SIM failure

In the home screen from Quectel IMSI and ICCID are not displayed (when I put the SIM straight in the dev board, it shows these values correctly).

So could anyone give me some hints what I’m doing wrong or what to verify please?

Kind regards,
Hugo
