About NxpNci20

[yanpuja_yh]

In NxpNci20Catch's "NxpNci_CheckDevPres" function, "tml_Receive" function to do "Catch potential notifications", But I received 3 bytes, first is 0x40, second is 0xFF, third is 0xFF. It seem except for first one, the others are errors. So anyone who can explain what is the meaning for error message, thank your help for advance.

Hi Daniel

  Thank you very much for your reply.

  I checked Section 5.3, but didn't find the answer.

  Maybe I don't describe the question clearly. Sorry for that. I mean when I use  NxpNci20 interface

library, especially on former question, I received answer from  PN7160, then in library there are many

magic numbers answers like as in former question. I want to know where can I get some information

to explain such magic numbers to help me to debug my R/W board.

Looking forward to your further answer and thank you again.
