    Ext.length response to non-extLength command request

    925183
      Hello,
      i have a problem with sending an extended length apdu
      the command is 00 B0 00 00 00
      which means READBINARY with Le = 00
      Referring to ISO7816-4 this means:
      "If the Le field contains only bytes set to '00', then all the bytes until the end of the file should be read within the limit of 256 for a short Le field, or 65 536 for an extended Le field. "
      So the command requests 256 bytes of data.
      As i need to wrap the data in SecureMessaging i need more than 256 bytes of data
      problem occurs with apdu.setOutgoingLength() > 256 if receive 6F00
      any ideas?
      Thanks in advance, Paul
