The payload is copied before the id, which results in a corrupted record. The payload should be copied after the id.
The bug is between lines 173 and 180 of NdefRecord.cpp

I'm not sure if this relates to the "shouldn't block" issue but I discovered nfc.tagPresent() takes about a second to complete, delaying my run loop.

I guess my question is, should I expect it to take a second, which appears to block? What do you think is responsible for the delay and what do you recommend I pursue to overcome it?

Note, I am using the Grove NFC module (not the shield version). It uses UART by default. Though it says you can modify the board to use I2C, I (and others apparently) cannot get that to work. In order to get this NFC library to work, I'm using this software serial, PN532_SWHSU PN532Interface I found. My uC is a Huzzah ESP8266. Everything is actually working, it's just the delay I'm wondering about.

Thank you for your awesome library!

Hi,

I'd like to know what is the maximum text length to store in an ndef text record?
Thank you.

Hello don,
I explain my situation :

I have a Yùn board with nfc seeedstudio plug on it.
I have a Sony Xperia SP as mobile.

I load the nfc arduino program called "P2P receive" on the arduino board.
I wrote a cordova app that use this library : https://github.com/chariotsolutions/phonegap-nfc

Then, i share content to the arduino via my app (share, not write)
And i got results.

But i cannot see what i sent from my phone.
I get two NDEF messages, one thet say it came from my phone with the package name and another that link to the play store to my app and it is concatenate with "&beam" or something like that.
(i'm don't have the board right niw with me)

Any help or suggestions ?
I hope i was as clear as possible ^^

Thank you very much in advance.

Edit: I share a textrecord

is it possible to have a timeout on nfc.begin? in case the board isnt connected so the rest of the code can continue to function.
it looks like it just hangs once it says 'Didn't find PN53x board"

Hello Don

I like to use ESP8266 as the micro controller. Do you think if it is possible?

Best regard

Saeed

PS. Thank you very much for this nice library

I'm trying to write to a NTAG215, which has around 504 bytes of usable memory, yet I can only seem to use 227 (255 with headers ect.) bytes with the message.addTextRecord(input) function.

Basically I have something that looks like this:

#include <SPI.h>
#include <PN532_SPI.h>
#include <PN532.h>   // The following files are included in the libraries Installed
#include <NfcAdapter.h>

PN532_SPI pn532spi(SPI, 10);
NfcAdapter nfc = NfcAdapter(pn532spi);  // Indicates the Shield you are using
String input;

void setup(void) {
  while (!Serial); // for Leonardo/Micro/Zero
  Serial.begin(9600);
  Serial.println("READY"); // Header used when using the serial monitor
  nfc.begin();
}
void loop(void) {
  while(Serial.available() > 1) {
    input = Serial.readString(); } // read the incoming data as string

  if (input.indexOf("write") >= 0) {
    if (nfc.tagPresent()) {
      NdefMessage message = NdefMessage();
      input.remove(0,6);
      message.addTextRecord(input); // Text Message you want to Record
      boolean success = nfc.write(message);
      if (success) {
          Serial.println("COMPLETE"); // if it works you will see this message 
      } else {
          Serial.println("FAILED"); } // If the the rewrite failed you will see this message
    }
  } // End of write
  while (nfc.tagPresent()); // Wait for tag removal
  input = "";
}

Which works fine, until I exceed 227 characters.

Any ideas?

nfc.tagPresent() shouldn't block

I get "Read failed" debug message or "Error. Block Authentication failed for" when NFC tag quickly removed from PN532 and UNO or MEGA duino crashes or freezes caused out of memory.
Before that Serial monitor print wrong symbols in one string first shows russian (cyrillic) symbol "р" and after that only unprintable symbols.
I see there should be some Errors handlers but no idea how to limit the length of ndef message that causing crashes.
It happens on ReadTagExtended example.

Please, help with Errors handlers in MifareClassic.cpp
#50 fix this at all.

Hi, im use this code for store NDEF to String variable
String payloadAsString = ""; for (int c = 0; c < payloadLength; c++) { payloadAsString += (char)payload[c]; }
I would comparison this variable with Another variable
for this job I have defined a variable and inside it saved The string to be compared and compare this one with Posted NDEF meesage by tag or other nfc device.
But when i send equale string my answer of copmare is negative

Actually MifareUltralight class does not support tag write. Please implement write capabilities.

Null TLVs should be skipped when reading data in MifareClassic::getNdefLength

Currently handles 2 leading nulls, could be any number.

Sometimes when nfc.read() and it fails to read the NDEF records the arduino crashes.

Stacktrace:
nfc.read()
MifareUltralight(uid, uidLength)
NdefMessage(buffer, messageLength()CRASH!

I think the issue is when the messageLength is set to 0, so fix this I suggest that we change the comparison operator in NdefMessage.cpp from:

`
...

while (index <= numBytes)

...`

to
`...

while (index < numBytes)

...`

Hi Don,

I would like to ask for help, I m currently using your library of NFC to send messages to android over p2p protocol. I would like to send at least 2000 characters.

Is It possible or it is given by the hardrware PN532, I use ESP8266 and now I'm able to send 223 byte. I know that the library limites the number of bytes "SNEP packet, the packet should be less than (255 - 2 - 3) bytes". My question is if it was possible to send over this limit?

Thank you very much for your answear and your help,

Lorant

Writing multiple times a NFC tag causes a memory leak.
I've changed the NdefRecord deconstructor in this way to prevent the leak:

NdefRecord::~NdefRecord()
{
    //Serial.println("NdefRecord Destructor");
    if (_type)
    {
        free(_type);
    }

    if (_payload)
    {
        free(_payload);
    }

    if (_id)
    {
        free(_id);
    }
}

Is it possible to launch an app while scanning the nfc shield ?
(Like an AAR Android Application Record)

When running the ReadTag example on Arduino I can read most tags, but I have a specific example, 56 bytes long entry (56 character a) when reading it, it crashes. If I simply add one more byte to the tag it works as expected.

As far as I could debug using some Serial.println it crashes in NDefMessage.cpp at byte tnf_byte = data[index];

What i also found sometimes with the same tag, that it crashes in the record.setPayload... the reason is that payloadLenght has values like 50331648 or higher. But I cannot reproduce this one every time

Using NXP MIFARE Ultralight (C) NTAG213

Reading the tags on Android with NFC Tools (or android native) works as expected. Tags have been written with NFC Tools on Android

Any ideas for further debugging.

HI @don
kindly, i have arduino DUE, and Adafruit PN532 NFC/RFID Shield, and the only library which is compatible (as i heard) is the Adafruit_NFCShield_I2C library at: https://github.com/adafruit/Adafruit_NFCShield_I2C,

the thing is that i want to use the NDEF library developed by you (interacting with records is easy), but as i heard that it needs some modification to work with Adafruit_NFCShield_I2C library, so can you please help me with that.

Note: the reason im using DUE is because of its large memory

Hello, everyone:

I know this could be a silly question but I would like to know how to use NDEF_USE_SERIAL and NDEF_DEBUG defines in order to debug the obtained data in the NdefRecord.cpp and NdefMessages.cpp code.

I tried to insert both defines in the library code and the arduino code but I do not get extra serial outputs for debugging in the arduino serial monitor. I do not even know if the serial output of the library should be watch here...

I am using NDEF library with PN532 library from seed studio in order to use my NFC PN532 board to communicate with my phones.

Thank you very much in advance.

Hi,
Would it be possible to implement Desfire EV1: https://www.codeproject.com/articles/1096861/diy-electronic-rfid-door-lock-with-battery-backup

What would be the steps involved to do this?

• Add desfire drive and tag-type in nfcadapter.h
• Add desfire in nfcadapter.cpp at NfcAdapter::guessTagType
• Add MifareDesfire.h and MifareDesfire.cpp
• ...

In "MifareUltralight.cpp", the function "isUnformatted" returns false when the tag is not formatted.

The function "read()" never displays the warning message and returns an NfcTag with an empty NdefMessage. (and subsequent calls to "tag.hasNdefMessage()" return true).

When I changed the code so the function "isUnformatted" returns "false", the warning message is displayed and subsequent calls to "tag.hasNdefMessage()" return false.

Hello everyone, i wanna ask about p2p nfc-arduino, i'm using nfc shield v2.0 for my final assigment build securing lock door using nfc on smartphone. using mode p2p, the project is when user send a payload+record(ndef message) from smartphone using "LEGIC NFC P2P EXAMPLE" application and tapping it to nfc shield then nfc shield on door will read it, and check if ndef message true, the system will open. and i get stuck on condition system or arduino (microcontroller) didnt read any condition true or false. here i give some screenshot. can u help me guys?
thanks

@don , I could really use your help on this! I suspect it's a very trivial question.

I see in the readme that the libarary should work with my Adafruit PN532 breakout board, but I am constantly getting the "Send a message to Peer Failed" print.

I am using the Adafruit PN532 Breakout walk-through to configure the wiring for SPI, and the example files work in the Adafruit library.

However in order to get P2P working with Android, this library seems like my best option if I can just figure out why it's failing.

Can you please provide an explanation for what this code in your P2P Send example:

#include "SPI.h"
#include "PN532_SPI.h"
#include "snep.h"
#include "NdefMessage.h"

PN532_SPI pn532spi(SPI, 10);
SNEP nfc(pn532spi);
uint8_t ndefBuf[128];

means, versus this code that is used in the Adafruit examples:

#include <Wire.h>
#include <SPI.h>
#include <Adafruit_PN532.h>

// If using the breakout with SPI, define the pins for SPI communication.
#define PN532_SCK  (2)
#define PN532_MOSI (3)
#define PN532_SS   (4)
#define PN532_MISO (5)

??
I'm confused whether this code is suggesting a different wiring or what could be going on.

Any help would be so greatly appreciated! Thank you!

Don
My understanding is that the NTAG 2xx are an evolution of the Mifare Ultralight
Is your NDEF library compatible with the NTAG 203 and the new NTAG 21x?
I need to write an NDEF text and then read it

thank you

The TLV encoding for MifareClassic only works for messages < 256 bytes

Hi I'm trying to send a message to a phone, I using an Arduino Uno with a PN532, I have fail to send message and nfc.write(ndefBuf, messageSize) returns -1, how can I fix?

How to add timeout ?

Will this work with NTAG 216 cards and will it also work with PN7150 reader?

I am using a elechouse pn532. I am sending a ndef message from an android device using beam. My pn532 only reads the rfid of the phone not the message. When i try p2p recieve example it does not work. I think the wiring might be wrong. How can i fix this?

Hi!
I am trying get 2 Arduinos to communicate with each other using NFC using your library.
I made one Arduino the Sender and the other the Receiver, but there no data is being sent. Not sure if I am doing something wrong or if the library is not read it.
Hope you can shed some light in this problem.

Thanks!!
John

Hi, is it there any form to get the message that is in the NFC card and store it in a String variable in Arduino?

Thanks!

Can I use P2P with other devices, such as this?

Hello
I have two questions regarding this post, is it possible to use the code to have two PN532 arduino communicate with eachother? Because whenever I try sending a message I always get a failure notification.

The second thing is it possible to have the communication established through I2C as well ?

Indentation is inconsistent.
Re-indent to 4 spaces, remove trailing whitespace

The payload is incorrectly read on some type 2 tags. Depends on the data not the tag.

See below. 'green' is read OK. 'blue' ends up as 'bl..'

Payload length is correct, data is incorrect

Hi there !

Congrats for this nice library. I have 2 questions. Sorry for that but I couldn't find an online reference/doc somewhere beyound github.

QUESTION 1 : about writing

I am triying to write stuff to a MIFARE CLASSIC card.

I tried to use either :
ndefMessage.addTextRecord("hello, world");
or
ndefMessage.addUriRecord("http://arduino.cc");

However I need to write new stuff to prewritten tags. I would like to do it on sector 3 for example, because sector 1 already contains data. Is there any (easy) way to do this ? So far it seems to be written on sector 1 ?

QUESTION 2 : about storing data

Also when I get the records, the data begins by either a . or a .en (or a square !)
I saw the example on github to print the data to serial and it looks fine, however I need to store it into a variable. I kinda manage to do it but it looks pretty ugly. Is there a nicer way to do it ?

for(int i=0;i<message.getRecordCount();i++)
{
NdefRecord record = message.getRecord(i);
int payloadLength = record.getPayloadLength();
byte payload[payloadLength];
record.getPayload(payload);
String data = (char *)payload;
data = data.substring(3,data.length()-2);
show(data); //my own method to print to serial. Could be serial here.
}

Thanks a lot !

Hey,
In your description, I saw that this library should good for my project. My goal is to read and send messages with a smartphone with NFC. I tryed the P2P_Send example.

When I introduced your library and chanch the follinging in the code:

#include <Wire.h>
#include <PN532_I2C.h>
#include <PN532.h>
#include <NfcAdapter.h>

PN532_I2C pn532_i2c(Wire);
NfcAdapter nfc = NfcAdapter(pn532_i2c);

i got the measege that #include <PN532.h> where not include.
After I added this library, I received the following message:
