Is it possible to write data to specific blocks in memory on the NfcV (ISO 15693) tag? E.g. write data to block# 5 or any specific block#.

    Tried the following: Getting the "Tag was lost" Exception:

            nfc.connect();
            byte[] arrByt = new byte[7];
            arrByt[0] = 0x40;
            arrByt[1] = 0x21;
            arrByt[2] = 0x06;
            arrByt[3] = 0x00;
            arrByt[4] = 0x00;
            arrByt[5] = 0x00;
            arrByt[6] = 0x00;           
            byte[] response = nfc.transceive(arrByt);
