PN532 NFC RFID Modul V3 Setup

PN532 NFC RFID Modul V3

macOS Setup

  1. Open the command line
  2. brew install libnfc
  3. nfc-list
    Note down the serial port e.g. pn532_uart:/dev/tty.usbserial-1440. If your device is not listed check if you connected the TXD and RXD wire correctly. You can also check the tty and see where the usbserial adapter is connected to with ls /dev/tty*
  4. cd /usr/local/Cellar/libnfc/1.8.0/etc/nfc
  5. Open libnfc.conf
  6. Add the following lines (use for device.connstring the serial port from step 3.) 
    device.name = "PN532 NFC Board"
device.connstring = "pn532_uart:/dev/tty.usbserial-1440"
  7. Now everything should be setted up and if you place an nfc tag on the module it should be found by nfc-poll

Read/Write NDEF messages

To be able to read or write NDEF messages you can use the command line tool libfreefare.

  1. Open the command line
  2. brew install libfreefare
  3. Create a textfile for example helloWorld.txtand add the following content Hello NFC World!
  4. Place an nfc tag on the modul and execute the following command:
    mifare-classic-write-ndef -y -i helloWorld.txt
  5. Now the message should be written on to the tag and you can read it from there with:
    mifare-classic-read-ndef -y -o readdata.txt
