Hi All,
I am new to the group. I have Turbo Programmer Kit and want to do development in SIM ToolKit but I don't know how to start. I am able to install the binutils and gcc for avr as mentioned on the site. I am also able to compile and load the helloworld.trb on the kit.

The command "prog_apps -a app_nr -x 128" doesn't return the "helloworld!" string but instead it returns the hexequivalent of the string.

Can anybody guide me how to start for SIM ToolKit Application development.


Thanks & Regards
Nand Kumar

Could you post what exactly are you doing, e.g.. screenshot, redirect you cmd to a log file? Thank you.

Hi pz

Thanks for the quick response. I have to develop SIM Application Toolkit for mobile. That should be able to take the information of the service provider and able to display on the screen according to our wish.
For that I have Turbo Programmer and all the softwares required for the same. I dont have any fake sim or Turbo Sim. I also don't have the Turbo adapter too. Is it possible to develop the same.

How to procede and what are the other hardware required for the same.
I also dont know how to use the debugger.

Thanks in Advance
Nand.

Hi pz

In India like Idea service provider provides "Idea Power" on therir sim and Hutch Service provider provides "Hutch Alive". When you insert the sim in you mobile phone it display in the menu that "Idea Power" or "Hutch Alive".
Now I have to write an application for "Turbo Programmer 2" so that I will be able to see the "Idea Power" or "Hutch Alive" and the list of subactivities inside that menu. Is it possible ?
If yes then what are the steps and what are all required in software, Hardware for the same.

I didn't find any document that how to use the "Turbo Programmer 2" for application development. There is one document for the Hardware specification for the same.


Thanks
Nand.

Hi pz
If I am not wrong then "SIM Application Toolkit ( SAT )" is provided by Service provider. And I am working for Mobile phone. Presently Mobile hardware is capable for SAT but there is no software written to access that list like "Idea Power" and "Hutch Alive".

Now I have to write application for that so that it will communicate with the SIM card through "wavecom AT Commands" to enable that list and show as an activity or subactivity.

As there were no method to debug on the phone. So we have taken TP2 and write code and debug here and then similar code will be written for the mobile.


Thanks
Nand

Hi pz
Thanks for your reply. And now the things are getting much clear but still many of the things are still not clear.

Hi pz
Many many thanks for your reply. Now I am undergoing the 11.11 and 11.14 documents.

Meanwhile I am trying something with the given examples. I have loades the sysinfo.trb with the following command :
prog_apps -u sysinfo.trb
And with the prog_apps command I get the following output.
--------------------------------------------
[root@localhost src]# prog_apps
Programmer application list:
0: avrprog.trb
1: df.trb
2: sim.trb
3: turboadapter.trb
4: sysinfo.trb
[root@localhost src]#
---------------------------------------------
It hangs after giving this command, the LED goes to PRG mode and then we have to kill it.
[root@localhost src]# prog_apps -a 4 -x 10
Send action 10 to app 4
---------------------------------------------

Bui I am unable to do anything with it. How to get the information and what all can we do with this. Can you give write the sequence of command to for sysinfo.trb and what output if should provide.
Also how to use the dbg utility with TP2.

Thanks a lot
Nand.

Hi pz

Thanks a lot. Now with your help & guidance I am able to communicate with the SIM and able to get the "Hutch Alive" and list of SubActivities.

My work has just started and in future if I face any problem then again I will take your help.

Once again very-very thanks to you.

Regards
Nand.

Hi all

Can anybody tell me that can I write any file on the SIM card provided by the service provider. Or what are the possible way in which I can write my own file on to the SIM card.
Is the file stored on the SIM are binary file or Hex file or any other file format.


Thanks in Advance
Nand.

Hi

I had the same problem to find out how to put own Applets on the SIM Card. Finally I've found this out.

So:
1) To put your Applet on the SIM Card.
a) Write your applet in you favorite editor. Note! You have to do it in Jave (I hate Java, but JavaCard is very similar to C - at least this).
Under http://java.sun.com/products/javacard/dev_kit.html you'll find documentation for the
import sim.access.*;
import sim.toolkit.*;
import javacard.framework.*;

files, as well the include files itself. This is a must to compile the applet!
b) next step is to download the Applet to the SIM Card. For this I'm using Interportable Applet Loader form SimAlliance. you can get this tool for free from www.simalliance.org. In the package you'll find as well some demo applets - it is very usefull for beginners.

Notes:
- To upload an Applet on the SIM Card you have to have the KID and KIC key's to your SIM Card. Without them you can do nothing! To get them you have to ask your Mobile provider, but as far I know you'll never get them if you do not know any insiders there.
- Writing Java applet - remember that each declared variable is allocated in EEPROM. all variables that are very often used (for ex. for loops, counters etc). should be allocated in RAM! otherwise you'll decrease the liftime of the SIM Card.
- Instead of declaring 10 Variables (for example 1 byte) use an Array of bytes. For each allocated variable system will consume 1 or 2 extra bytes. In first example the real memory used will be 30 bytes, in second only 12 bytes.

2) Creating new Files / Directories on the SIM Card.
Generally it depends on your SIM Card Chip (and COS). I've 2 generations of SIM Cards from Axalto. On the old generation it is not possible to create new Files, on the new generation you can dynamically create/delete/resize files on the SIM Card.
To do this you need:
- SIM Card Documentation (especially the F0 class APDU's which are used for programming the SIM Card).
- if you want to "talk" with the sim directly with APDU's - you need the Admin key _or_ you can encapsulate all APDU commands into SMS - for this option you have to know the KID and KIC (as well the indexes).

Generally if you have these Admin keys you can do everuything with the sim card, even chage the PUK/PUK2 as well the number of retries (from 10 to 99) etc.

3) Development
At the beginning I was using Bladox as Tracer ME <-> SIM - it is very good tool for beginning, but after some hour's spent on swapping The SIM from Reader into ME, booting the ME etc. I've decided to buy an ME Simulator. Here you do not need to work with hardware, you can completly develop and test your applet on your PC. you can see as well all SIM<->ME Traces and in better Simulators - internal memory of the SIM Card!
(on google you'll find some)

Hope this will give you some idea about writing applets to the SIM Card.


Cheers
