I actually own a APDB2UA33 OEM module. For my first try, I had used a
USB-UART converter to connect the OEM module on a PC.
I had compiled libnfc 1.2.1 using --enable-debug flag (under GNU/Linux)
and had executed nfc-list:

Since r105, PN532 UART based NFC devices can be used with libnfc without
any stability issue... But we have to use a delay in dev_arygon.c (around
50ms to be stable).
This delay is needed to receive a full TAMA frame for PN532.
Unfortunately, if we use a slower transmission like 9600 baud, this delay
have to be extended or it appends this:
TX: 32 00 00 ff 04 fc d4 4a 01 00 e1 00
RX: 00 00 ff 00 ff 00
TX: 32 00 00 ff 04 fc d4 4a 01 00 e1 00
RX: 00 00 ff 0f f1 d5 4b 01 01 00 44 00 07 04 a3 12 61 ee
02 80 09 00 00 00 ff 00 ff 00

02 80 09 00 00 00 ff 00 ff 00 00 00 ff 0f f1
TX: 32 00 00 ff 04 fc d4 4a 01 00 e1 00
RX: d5 4b 01 01 00 44 00 07 04 a3 12 61 ee 02 80 09 00 00

02 80 09 00 00 00 ff 00 ff 00 00
If you take care: RX start doesn't and TAMA start does match each time.
The cleanest way, IMHO, is to retrieve TAMA frame from RS232/UART using a
circular buffer which is able to keep all received bytes in a buffer and
export only full TAMA frame.
Using this way, we will be able to check TAMA frame struct (length and
checksum).

- It starts in "sleep mode" and needs a specific command to wake-up.
- It only works in handshake mode.

We may want to consider nfc_initiator_select_tag() to be renamed to
nfc_initiator_select_target(). Where we use the "pbtInitData" parameter for
(structs & unions) that corresponds to the active "init_modulation" type.
For DEP transactions this could hold pbtPidData/pbtNFCID3i/pbtGbData (using
structs & unions). This may improve the understanding of "pbtInitData" for
developers, since they are guided by a struct to supply additional info.
Furthermore this will bring down the total amount of "similar-code", plus
it will keep the API tight and clean.
Last but not least, we could save the current used "init_modulation", to
cut down the extra "tranceive()" functionality, since this only differs in
the command for the PN53X chipset.

The files libnfc.h and bitutils.h need the following in the header.
#ifdef _WIN32
# ifdef nfc_EXPORTS
# define NFC_LIB_EXPORT __declspec( dllexport )
# else
# define NFC_LIB_EXPORT __declspec( dllimport )
# endif
#else
# define NFC_LIB_EXPORT
#endif
Furthermore, for every function that needs to be exported (i.e.: callable
from the outside world) should have "NFC_LIB_EXPORT" prepended.
Example:
NFC_LIB_EXPORT dev_info* nfc_connect(void);
In bitutils.h the functions "print_hex*" and "swap_endianess*" also need to
be "exported" because some tools use them.
These header modifications will be used by CMake to generate a DLL + LIB
file for libnfc.

The library is not correctly linked in a C++ environment.
Reference:
http://www.dwheeler.com/program-library/Program-Library-HOWTO/x214.html
The solution is:
1) Define a macro in "defines.h" like this:
// Linkage specification macro
#if defined __cplusplus
#define NFCAPI extern "C"
#else
#define NFCAPI
#endif
2) Add "NFCAPI" prefix before each API method signature:
/* libnfc.h */
NFCAPI dev_info* nfc_connect();
/* libnfc.c */
NFCAPI dev_info* nfc_connect()
{
// ...
}

There are two issues when packaging for Fedora:
1. The std=c99 CFLAGS should not be used on Fedora (Fedora 11, GCC 4.4),
with it the software won't compile, without it everything works fine (I
created a patch to fix this for Fedora). I'm not sure it compiles on
Debian/other systems without this CFLAGS?
2. The use of rpath. This is deprecated, also on Debian, but by default
rpath is included. I "fixed" this by re-running libtoolize on Fedora which
takes care of this, it does not seem to be possible to just modify the
libtool script ./configure generates.
Is it possible to remove the "std=c99" or will this be a problem for other
platforms?
It it possible to "fix" libtool to not include rpath by default? Or have
some configure parameter for ./configure which takes care of this? (e.g.:
--disable-rpath)

I've created a few CMake build system files for libnfc as an experiment.
There are still some issues on Windows, and windows support is not part of
the current CMake scripts, but on Linux it seems to work great (tested with
Fedora 11 and Ubuntu 9.04).
On Windows I get a bit confused about the winscard.DLL/winscard.LIB files
etc and how to generate a LIB file from a DLL file. CMake can automatically
generate Visual Studio project files for any version, so that would be a
nice benefit!
Although when using the winscard.LIB file that is now part of the SVN repo
it all seems to work, but it is not really nice to have a blob in the
source repo.
I attach two files, CMakeList.txt which should be placed in the project
root and CMakeListSRC.txt which should be placed in the "src" directory and
also have the name CMakeList.txt. To compile the whole stuff (out of src
tree) create for example a directory "bin" in the project root:
$ cd /path/to/libnfc-1.2.2/
$ mkdir bin
$ cd bin
$ cmake ..
$ make
$ sudo make install (installs in /usr/local/*)
Maybe at some point (when the Windows issues are resolved) it can be
considered a replacement for Autotools.

Currently, the PN532 UART driver seems to be very slow compared with a
Nokia NFC phone (read and write actions on Mifare tags).
The main cause seems to be the 50ms delay added to the "transceive"
function for stability needs. So, I've tried to remove it and...surprise!
It works! :)
With the delay I need 18~20s to read/write a Mifare Classic 1K tag. Without
it the tag is written/read in ~10s. It's still slower than the Nokia phone
(which reads a vCard from a Mifare 1K in only 1~2s), but surely more
acceptable.
Probably the magic is done by recent changes to UART read/write functions
(r183, r184).
So, in my opinion, we can remove it if the situation is confirmed by more
accurate tests and benchmarks.

Current svn trunk (r99) can now handle a NFC connection to a specified
device. For ARYGON readers (and PN532 using UART) serial port can be
specified but not serial speed.
Actually speed is hardcoded (in rs232.c) and can become a problem if a
serial NFC reader doesn't use 115200 bauds.

I added NFCIP support to libnfc. It is a messy patch, but it works (see
included initiator and target example apps). You need two readers to test
this. The initiator and target send each other a simple "Hello World/Mars"
message.
Issues with the patch:
- I copied some functions and added "dep" in their name when the PN53x
instruction is different, this could be optimized a bit by having some kind
of configuration somewhere to indicate that DEP / NFCIP is used
- NFCIP needs to activate the target, which is something else than
selecting it apparently (different command)
The patch is against latest svn (r71).

It would be nice to have an "auto-authentication" option in "mftool".
Usage example:
mftool r a dump.mfd
(this is the new usage form)
mftool r a dump.mfd keys.mfd
(please, note the switch between dump and keys for the old usage form)
If no "keys" dump file is specified, the tool tries to authenticate with a
standard key list:
byte_t keys[] = {
0xFF,0xFF,0xFF,0xFF,0xFF,0xFF,
0xd3,0xf7,0xd3,0xf7,0xd3,0xf7,
0xa0,0xa1,0xa2,0xa3,0xa4,0xa5,
0xb0,0xb1,0xb2,0xb3,0xb4,0xb5,

0x1a,0x98,0x2c,0x7e,0x45,0x9a,
0xaa,0xbb,0xcc,0xdd,0xee,0xff
};
Pseudo code:
// Set the authentication information (uid)
memcpy(mp.mpa.abtUid,ti.tia.abtUid,4);
// Determin if we should use the a or the b key
mc = (bUseKeyA) ? MC_AUTH_A : MC_AUTH_B;
int num_keys = sizeof(keys) / 6;
for (int i = 0; i < num_keys; i++)
{
memcpy(mp.mpa.abtKey, keys + (i*6), 6);

I created a NDEF parser example tool (nfc-ndef) that at this time can parse
a MFUL tag (among others the one from Tikitag/Touchatag) to extract the
NDEF URL stored in it.
The code is universal in that it is easy to implement support for other
NDEF tags / message types as well, but it seems this one is best suited as
an example as most people will have the Tikitag tags lying around. In the
future a complete NDEF parser may be a possibility separate from this
project (as part of nfc-tools project?)
Extending it to MIFARE Classic support (1k/4k) is trivial.
I didn't want to commit it just yet as the source style / copyright etc.
may not be what is required for this project :-) I used "indent -kr -i4" to
format the source. It's been a while since I was fluent in C :-)

The code currently contains:
if (!bPar) nfc_configure((dev_info*)pdi,DCO_HANDLE_CRC,true);
which sets the CRC property based on the bPar flag. There's a section
further on that sets it back similarly. This should probably set the
PARITY property instead.
I haven't created a test case from this, but it appeared pretty clear what
the code was intended to do, and what it actually does. I've attached a
