Hi all,
congrats for your awesome research and work, this is truly impressive.
The little ant that I am (compared to you) was interested in helping you with the SIM aspects of the project. I think I know javacard sufficiently to implement a basic sim card that can be totally controlled. I already started to think on how to do that. This will include making host side tools, too. If javacard is not open enough, we can also look at native cards using PIC, for example. In our previous discussions, the main problem was the availability of SIM sized cards, be them javacards or not.
pros and cons - javacard is an industry standard, coupled with GlobalPlatform specs this is a portable way to put an application on a card without being locked with a card manufacturer. - native PIC cards benefit from a lot of open tools such as the gp* PIC tools, asm, sdcc for compiler and gpsim for simulation. - some projects exists already, I don't know them well, maybe they can be used, forked, improved. - availability must be checked.
I'd like to request precisions on how the things should be done, what are the minimal requirements (files, etc) and when the openSim project will be needed regarding to your progress.
Regards Sebastien

I only want to say that i am courrently drive a semilar project. I have developed a smartcard O/S for Atmel-Cards (license is GPL, of cause....)
http://runningserver.com/software/xcos.tar
Currently i am working on a simcard implementation. Currently my simcard can process SELECT commands (but not READ BINARY & Co so far).
The download link leads to the current release (which does not include my simcard source). If you are intereted to see the source of my unfinished sim project i can make it available.
I can not say when my simcard gets finished because there are a lot of other important (and sometimes more interesting) things to do.
Best regards. Philipp
Regards Sebastien
Hi,
I'll have a look at it, thanks. Same as you, I have lots of things to do, so my project will also take time to complete. It's good to know we'll have more than one implementation available.
Regards Sebastien.

I think it would be more productive if you could divide the work rather than duplicating it. If dexter already has the 8716 part done up to SELECT FILE, then it might be more useful to add the SIM specific bits to it.
Also, if you want to work with SIM cards: We still need the phone-side implementation for OsmocomBB, i.e. a driver for the SIM reader inside the phone, plus a software layer that provides a filesystem-level API where we can simply call functions lieke iso7816_read_file_record() that would * selects a file * reads a caller-specified record * copies the result in a caller-provided buffer
To make it short: There is a lot of work to be done, and I would rather like to see the two of you to work on separate tasks, rather than duplicating work.
After all, we want to see as much progress as possible and can need all help we get.
