Problems to recognise the NFC tag with the ST25 app.

[Ferry66]

Hi @Cedric Dalban @JL. Lebon,

I have changed the RF register in the ST25 application on my mobile phone and now I cannot communicate with the ST25DV6564KC chip, it does not recognise the tag. Even if it is powered by an external battery.

I have tried to make changes to the software and have implemented the following function:
CUSTOM_NFCTAG_WriteI2CSlaveMode(<your instance>, ST25DVXXKC_SLAVE_MODE_NORMAL);

but it still doesn't read the tag.

What could be the reason why I can't read the tag now?

Hello, 

I would need more details in order to help you.

"RF register in the ST25 application on my mobile phone and now I cannot communicate with the ST25DV6564KC chip, it does not recognise the tag"
Do you know which register you changed?
Is your communication lost only on the RF side, or is it lost also on the I2C side?

Best regards.
