PN532 is used as reader to communicate with NT3H1101,which is monitored by serial debugging assistant. Only three commands of initialization, finding Ntag and disable RF are ok,while others are of failure. Debug screenshots are below in detail:

In the screenshot, commands in order are following:

(1)55 55 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ff 03 fd d4 14 01 17 00

(2)00 00 ff 04 fc d4 4a 02 00 e0 00

(3)00 00 FF  13  ED  D4  40  01 60 07 FF FF FF FF FF FF 04 97 91 52 56 40 80 F6 00

(4)00 00 ff 05 fb D4 40 01 30 07 B4 00

(5)00 00 ff 15 EB D4 40 01 A0 06 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F CD 00

(6)00 00 FF 04 FC D4 32 01 00 F9 00

The reply to command of getting UID is abnormal. Byte of memory size is 0x00. I wonder the reason. If it is not 0x00,whether read/write operation will succeed?

Wish your relay!Thanks.
