ST25R3920B for OOB Bluetooth Pairing

[JPortilha]

Hello everyone,

I am using the X-NUCLEO-NFC08A1 NFC Shield that has the ST25R3920B chip. I want to know if it is possible to use this to make OOB Bluetooth with my android smartphone, and if so how can I achieve it. I read some documentation regarding the demos in X-Cube-NFC6 with card emulation, but I don´t if that is suitable for what I am trying to achieve.

Hi JPortilha,

yes, you can find exactly such an example in stsw-st25r-lib. Just look for the pairing example.

Hello, I have already downloaded that lib (for the 20 series), however I am still having some troubles.

First of all, I am not finding the pairing example. I have searched through the files but I am not seeing where the Bluetooth pairing information is being written into the NFC shield, and how the shield is being emulated like a tag for the purpose.

Secondly, yesterday I have included the files "demo_polling" and "demo_ce" into my project, however the NFC state is always changing between 'RFAL_NFC_STATE_POLL_TECHDETECT' and 'RFAL_NFC_STATE_POLL_COLAVOIDANCE'. The shield is not detecting my smartphone when I get it close to the shield.

Hi JPortilha,

I think your are using the wrong package. There is no "20" series. The STSW-ST25R200 is for ST25R100 / ST25R200 but not for ST25R3920B.

Hello,

I have noticed that. I tested the the package for ST25R3916 but it is not working, I don´t know if it is compatible. Can you provide an example fot the ST25R3920B?
