Read time stamp abnormal, Using PN7160 to read/write NTAG I²C Plus 2K tag problem

yanpuja_yh — Mon, 11 Jul 2022 22:34:48 GMT

I'm using PN7160 to read/write NTAG I²C Plus 2K tag. And using example of NXP revised program,

I found

"NxpNci_HostTransceive(NCIReadTS, sizeof(NCIReadTS), Answer, sizeof(Answer), &AnswerSize)"

return answer[1] = 0x02, from example, the correct value is answer[1] = 0x03.

Who can tell me what's the meaning is 0x02 or 0x03?

It is defined in NFC Controller Interface (NCI) Specification document

Hi Erklei

Thank you very much for your answer.

Could you tell me where can I get "NCI Specification"?
