Hi!
 
I need to change the protocol to T1 in the smart card reader of printer.
Is it possible to change the protocol from T0 to T1?
 
I am trying to do it the following way :
 
Command PPS :
byte[] PST_SELECT_PROTOCOL = { (byte)0xFF, (byte)0x01 , (byte)0xFE };
Response of printer : 1521 where 21 is Too short APDU
 
can anybody help me? , by the way i'm working Android application.
 
Thank you!
