Read UID ISO15693 tag with ST25R3911

[emil28]

Hello,

I am using the nucleo -nfc05A1 and I would like to use it to read the UID of a ISO15693 tag. I have followed the steps described in the datasheet in order to make the board ready to read card, but I don't what to put in the FIFO to have a response from the card. Do I have to send data or command in particular ? I am a lost and I don't know how to do.

Any pieces of information would be helpful.

Thanks

​Hi Emilien,

X-CUBE-NFC5 provides  a complete middleware to control applications using ST25R3911B. It includes a demo that reads the UID of tags and display the result on a serial console. It natively supports some STM32 MCU but is easily portable on other MCU.

Hi Brian,

Thanks for your quick answer.

I have downloaded the demonstration software, and programmed my nucleo F401RE. Unfortunately, the software never detects the tag when I approach it near the antenna. Do I need to change something (a parameter) in order to detect the tag ?

PS: my phone with NFC and the ST App ST25 can read the UID of the tag, read and write the memory.

Thanks.

Hello,

I just turned off/on the Nucleo, on everything works fine now.

Thanks.
