[Globalplatform-users] Interacting with an applet

[hkarahan <Hak...@es...>]

Hi,
I am trying to interact with an installed applet on the Nokia 6131. Is
this possible through GPShell? Is there some "run"-command or something
similar? Consider for example the HelloWorld.cap which comes with
GPShell 1.4.2, is there a way to really make it output something?

Thank you very much.

Best regards,
Hakan

Well, only rudimentary. There is the send_apdu command. See the README 
fiel. So you can write a script file with some send_apdu commands and 
talk to the card.

send_apdu -sc 0 -APDU xxx // Send APDU xxx without secure channel
send_apdu_nostop -sc 0 -APDU xxx // Does not stop in case of an error

You get APDU reponse messages from the card. It should be possibel to 
use the outcome of gpshell also in script files. If an error occurs you 
can ask for the return status (0 or 1).

gpshell reads by default from stdin if no script file is given. So you 
can also use it directly under a bash gpshell < send_apdu -APDU ...

I figured that out by now, but thanks for your reply anyway.
