Android : NFC APDU command response '6700' Wrong length'

Question

I am sending below APDU command to ISODep tag and I am getting '6700 wrong length'

byte[] command = new byte[]{ (byte)0x80,  (byte)0xD0, (byte)0x01, (byte)0x00, (byte)0x07,(byte)0x22 , (byte)0x22,(byte)0x12 , (byte)0x34 , (byte)0x56 , (byte)0x78 , (byte)0x90  };

Please suggest if something is wrong in above command.

Answer 1

You are sending a case 4 APDU there, right? Your Lc indicates 0x07 bytes of data, and there's a Le of 0x90 trailing. Check with your specification whether this command is actually expecting a case 4 structure, or whether you just got the data length in the Lc field wrong (0x08 instead of 0x07).
