Use P1P2 in APDU command

Post by ngana » Sun Sep 10, 2017 11:46 pm

I need to send APDU like /send b07000000411222233 to my JCOP31 V2.2 card. In above APDU, I am not giving any value of P1 P2 as this indicates some extra parameters. but if I want to use these P1P2, what should I do?

If you use proprietary ISO command (CLA byte = 0x80), you may choose your own P1 / P2 parameters. In case it is a GlobalPlatform compliant card, take care of therein defined APDU commands as they use also CLA = 0x80.
