This is the announcement for the next Osmocom Berlin meeting. Jun 27, 8pm @ CCC Berlin, Marienstr. 11, 10113 Berlin Nico will talk about SAP (SIM Access Profile) in osmocomBB. If you are interested to show up, feel free to do so. There is no registration required. The meeting is free as in "free beer", despite no actual free beer being around. Updates and the blog post can be found here[1].

First thing to do is a an interface to connect my PC with sim slot phone. So I am using this simple interface : I took a CP2102 module, see this page for example http://esaid.free.fr/Cdotnet/USB_serial.htm, then I have put a diode between TXD and RXD, then I have connected RXD to I/O of phone sim slot, DSR of CP2102 module to RESET of phone sim slot and connected the two grounds.          __________                                                       |         |________   TXD                               +5V------|         |     |                                        DP------|  CP2102 |___ \/__   RXD   -------  I/O phone sim slot  DM------|         |                                              GND-----|         |---------  DSR   ------- RESET phone sim slot          |         |                                                      |_________|--------   GND   ------- GND  phone sim slot I have tested this interface with a phone , I can detect reset from phone then I send this ATR: 3B 16 95 D0 01 7B BD 0D 00 ( this is the ATR I can read form a real sim card with a phoenix reader), but I don't have any response from phone. Any help is appreciated, thanks. -------------- next part -------------- An HTML attachment was scrubbed...

First check if this is matching. One important point is that you are completely ignoring the CLK pin. Thus you baudrate might not match the one set by the phone, and additionally you can also be out of sync with the clock. Some old phone have a fixed standard baudrate, that might help (use an osci to debug). kevin From lukash at backstep.net Thu Jun 28 11:36:13 2012 From: lukash at backstep.net (Lukas Kuzmiak) Date: Thu, 28 Jun 2012 13:36:13 +0200 Subject: help on pc-phone interface In-Reply-To: <1340882623-sup-3505@dennou> References: <2613c06082f485331455cdcafaa4608e@2.226.168.72> <1340882623-sup-3505@dennou> Message-ID: This is maybe a bit off-topic, but you may find easier implementing this as purely software/firmware thing for simtrace itself rather than building a separate device :) Cheers!

Usual solution is to have an open collector output with a pullup. Then you have all the issue where a phone could request change of speed via the special PPS procedure (IIRC) and I'm not sure you'd be able todetect and follow it. Adapting the fw of a simtrace board seems like a better solution. Cheers, Sylvain
