X-NUCLEO-NFC06A1 doesn't read and write any tag, "NDEF NOT DETECTED" error

[Wladimir]

Hello to all!

I have boards - NUCLEOL476RG and X-NUCLEO-NFC06A1 with project "STM32L476RG-Nucleo_PollingTagDetectNdef" running on it.

And got an error when trying to read any tag:

When debugging program i found that error, its here in the code, doesn't match

apduParam->statusWord == RFAL_T4T_ISO7816_STATUS_COMPLETE

The walue of statusWord is 27266 instead of 36864 (0x9000)

Appreciate for help and sorry for my english))

Hello, Ulysses!

At the moment, the problem is that in the Tag Emulation mode, writing to the "tag" works, that is, the content of the ndefFile changes to what I write, but when reading the content of the ndefFile changes to the default - "st.com/st25-demo".

I am trying to track the exchange of useful data between phone and board, I looked at the contents of the array txBuf[100] in demoCE() function, but I did not see the default content of the tag ("st.com/st25-demo") there during data exchange.

Best regards.

Hi VIVAN.1,

it makes me curious and I will try to find some time next week to debug into this. In case you have additional findings, please let me know!

Hi VIVAN.1,

Using v1.1.0 of X-CUBE-NFC6 I moved the demoCeInit() call from demoCE() to demoIni() and then the content of NDEF file started to stay in memory.
