Hello, I am trying to create a small project with my friend using Rpi4 with a PN532 NFC module. We are trying to communicate with an android smartphone. The smartphone supposed to read data from NFC first, then sends a data to NFC. But the problem is the documentation is very much limited. We are using Rpi4 with SPI communication on a PN532 and couldn't even find any usefull examples or libraries for this.
We tried libnfc:
and tried read with applications (android mobile phone samsung j7) which is nfc tools, nfc write, mifare classic tool but didn't get any response.
We used connect the nfc board for following gpio pins:
- sck = gpio 11
miso= gpio 9
mosi= gpio 10
ce(ssel/scl/rx) = gpio5
If you know a way for communication or any documentation about this subject, can you help us?
Have a great day.
