St25R95 library

[thompeters2004]

Hi,

I have successfully ported the ST25R95 library from STMicroelectronics to my own microcontroller, an nRF52832. I am now trying to read the payload of an NFC-A Passive ISO-DEP device with the UID: 5F471DC2783A8E.

In the polling_demo.c file, I see the function demoAPDU. I would like to use this function to read the payload, which contains Bluetooth Out of Band (OOB) data and a key. My goal is to use this for BLE NFC pairing. Can someone assist me with this?

Here is the payload:

Hi, 

I would look at ST25 embedded NFC lib which has examples for NDEF reading inside its ndef_rw_ demo (main logic triggered by file ndef_demo.c). The package for ST25R95 is STSW-ST25R017.

Hi,

as explained inside your previous post, you should use ndef_demo.c rather than demo_polling.c to read the NDEF from a tag (this is available from X-CUBE-NFC3 or from  STSW-ST25R017 package).

Hi,

I am now able to read the NDEF message, but I don’t get a Bluetooth address. Does anyone know how to fix this? Here is the output I’m getting:

NFC-A Passive ISO-DEP device found. UID: 5F471DC2783A8E
