communication between NFC MODULE V3(PN532) and NT3H1101

[jingjingliu]

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.

Hi Kan，

Thanks for your reply. I have solved the problem of communication between the two chips. 

The chip NT3H1101 is not like general MIFARE card，Its response to the command 0x4a of getting UID is right. And it doesn‘t need ID authentication. So ignoring the authentication， we can directly read/write the NTAG IC.

Best wishes.

Hi Jingjing,

Would you please specify which command you use to get the UID? Thanks for your patience!

Have a great day,
Kan
