Re: How to know Le in APDU command ?

It is managed by the CAD. In case of T=1, you can get the Le value directly. even there you can't be sure, because it also could be Lc. But in case of T=0 it is different, as the CAD sends only the header at the beginning. Then you need to evaluate Lc and optionally get the data with setIncomingAndR...

Re: Change Card Manager AID on JavaCard 3.x

Try to use 80 e2 80 00 0d 0070 0a 4f 08 a000000151000000 instead of the command you wrote.

Related commands:

RESET; 00a4040000; AUTH 3; 80e280000d00700a4f08a000000151000000; RESET;

Hope this can help.

Re: A client application

If you want something which works according to your requirements, I am suggesting to write your own PCSC wrapper using Windows dlls.
