In r509, a direct call to pn53x_transceive() was changed into a call to nfc_initiator_transceive_dep_bytes() which is part of the public API. The command to send was updated accordingly, but the code that extracts the response have not.
Update issue 98
This should fix the problem: because the response was not the expected length, the actual card data was not copied to the buffer, so it was always the same 16 uninitialized bytes that where returned for any block.

Pointy hat to: me
Or maybe I would rather have removed the const and called strdup(3)?
New issue
Summary: Sync code and comments
Owner: rconty@il4p.fr
Status: New
Romuald, can you please review this changeset and fix the code if I corrected
the wrong way (i.e. the comment was Okay and the code bogus while I fixed the
comment thinking the cod was right).
Thanks!
ISO C forbids empty source files. Instead of compiling possibly empty source
files depending on the compiler parameters, only compile required files to
build the library as requested at the ./configure stage.
Windows users (and more precisely non-autotools users), you may have to update
whatever you use to build the libnfc to fit your needs. The Makefile shipped
in the windows directory compiles all drivers as it is written so you should
not notice any difference, but if you don't use _that_ makefile, then you will
have to do some adjustment.
For now, keep the defines in CFLAGS just in case. Planned for removal in circa
one week.
While here, pet `./configure` output (--help format and summary).
I am sure we don't have /dev/ttyUSB*, and since I use /dev/cuau0 with a
cross-over cable to connect 2 machines and have a serial console, I guess
"/dev/cuau" is the SERIAL_STRING that's expected to work for me. A quick test
would be cool however, but I don't own a serial NFC device.
New issue
Summary: Provide a target listing function
Labels: Milestone-1.4.x
Libnfc lacks of target listing function. Actually, applications or libraries based on libnfc have to wrote their own listing function which can provide side effect if two or more of theses libraries are used together in the same application. Plus, some kind of problem could appears during listing multiples targets (i.e. collisions) and this problem should be solved in libnfc (i.e. using NFC chip capabilities), not in applications based on libnfc.
New issue
Summary: Catch unsupported command before sending to chip
Labels: Milestone-1.6.x
Actually, libnfc support PN531, PN532 and PN533 NFC chips, but the devices does not the same features. e.g. PN531 does not support ISO14443B modulation.
It should great to catch theses unsuported commands before sending to chip in order to prevent a chip error.
As the documentation states, and as reported in isssue 81 (fixed in r421),
usb_reset()'s argument is invalid after the call and so usb_close(3) must be
called before usb_reset(3).
The doc says LCS (aka abtTx[4]) must be set so that the lower byte of LCS+LEN
(aka abtTx[3]) is 0x00. This has not to be related to the USB buffer size, so
that we can adjust it without breaking down the libnfc.
- Complete indent(1)'s arguments list;
- Ensure files to be indented have no local edit;
- Hide indent command-line details. Since everything is static, no need for V=1 support.
