Hello all, I would do a sim-emulator software that runs on my PC.
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.
