Changelog for nfcpy

0.13.5 (2018-05-19)

  • Raise TagCommandError when NDEF data could not be written to the tag. Previously this was captured within the tag memory cache for Type1Tag and Type2Tag and only raised as IndexError.
  • Improved and corrected documentation for libusb Windows DLL installation (thanks to @ghxbob for PR #95 and @henrycjc for PR #112).
  • Identify Raspberry Pi via device tree model file (instead of /proc/cpuinfo).
  • Allow debug logs with python -m nfc -verbose to ease bug reporting when reader enumeration fails.

0.13.4 (2017-11-10)

  • Raise nfc.tag.TagCommandError when NDEF data could not be written to the tag. Previously this was captured within the tag memory cache for Type1Tag and Type2Tag and raised as IndexError.

0.13.3 (2017-11-02)

  • Corrects a documentation error about the errors parameter that is not used for ndeflib.message_decoder() as wrongly stated in a docstr embedded code example.

0.13.2 (2017-07-12)

  • Fixes issue #73 "Importing termios prevents operation on Windows" by catching the import error that occurs when running on a non-posix system.

0.13.1 (2017-07-01)

  • Restructured serial device discovery to find USB serial device nodes on Mac OS X.
  • Increased regression test coverage.

0.13.0 (2017-03-27)

  • This is a maintenance release to further replace the ndef submodule with ndeflib, now used by a couple of documentation examples verified with doctest.
  • Part of this release is a large number of regression tests run with pytest. Some minor source code changes are the result of testing and preparative work towards future Python 3 compatibility.

0.12.0 (2017-01-04)

  • Release 0.12 marks the end of code-transfer from Launchpad to Github (and bazaar to git). The Launchpad site will stay for questions and answers.
  • Release 0.12 also marks the begin of some code separation, starting with inclusion of the separate NDEF decoder/encoder module from https://github.com/nfcpy/ndeflib when installing from PyPI or running setup.py. The Tag.ndef attribute's new records member uses the new ndeflib for decode and encode.
  • New module main function for "python -m nfc" searches for locally connected contactless devices and provides diagnostic output for some known issues with access rights and conflicting drivers.
  • New iterations and interval options allow more fine tuning of the polling loop in ContactlessFrontend.connect().
  • New beep-on-connect option and implementation to let an ACR-122 blink and sound when a card is detected. Contributed by https://github.com/svvitale
  • Ability to apply factory format completely empty NTAG tags.
  • Correct dump of FeliCa Mobile data structures and timeout tuning for some older FeliCa cards.
  • A fix for the Raspberry Pi's erratic USB implementation, see https://github.com/nfcpy/nfcpy/wiki/USB-TTL-serial-adapter-on-Raspberry-Pi
  • A number of bug fixes, source code and documentation improvements including contributions by GitHub members https://github.com/pyrog, https://github.com/Skylled and https://github.com/hideo54.

0.11.1 (2016-04-29)

  • Fixes an error in in the authentication procedure for Ultralight-C and NTAG21x Type 2 Tags.

0.11.0 (2016-04-21)

  • The main new feature of release 0.11 is the support for encrypted LLCP connections from the NFC Forum LLCP 1.3 Specification. The feature is available for Linux systems with OpenSSL crypto library (probably all). Encryption is automatically used if the supported by the peer device.
  • The Python USB library has changed from PyUSB to the libusb1 module (pip install libusb1). This allows to wait for a USB response packet and still being able to cancel with keyboard interrupt (which PyUSB was unfortunately blocking).
  • Starting with this release the nfcpy library part (the nfc module but not the examples) will be uploaded to the Python Package Index for simple installation with 'pip install nfcpy'.
  • The Type 2 Tag sector_select command could finally be tested with an NTAG I2C Tag and is now working as intended.

0.10.2 (2015-10-02)

  • Fixes an initialization issue when PN532 is connected to serial port on Raspberry Pi.

0.10.1 (2015-09-28)

  • Issue warning when nfc/clf/pn53x.py is atttempted to be used as a driver (since version 0.10 pn53x contains only an abstract base class, drivers are in pn531.py/pn532.py/pn533.py).
  • Fixed an issue with PN532 deactivation - the chip needs additional time after change of serial baudrate before the next command may be send.

0.10.0 (2015-07-27)

  • Complete update of the tag read/write implementation to support features of specific tag products, such as password protection for Sony FeliCa Lite-S and NXP NTAG.
  • Type 4B Tags (ISO Tags) are now supported. This completes support for all NFC Forum Tag Types.
  • All contactless driver implementation is updated for generally more stability and an improved low-level API. The contactless frontend interface class and all ddrivers are now in one sub-package and emit debug messages with the logger "nfc.clf".
  • The TTA/TTB/TTF/DEP communication types are replaced by RemoteTarget and LocalTarget types with enclosed communication parameters that allow more control of the discovery process. This change is only relevant for application code that has set specifc poll targets or implemented card emulation code, otherwise it won't be noticed.
  • The contactless frontend connect() method understands some more options for callbacks and peer to peer communication settings.
  • Serial (tty) readers can be automatically discovered by probing ports and drivers. On Linux, the maximum serial baudrate is checked and configured up to 921.6 kbaud (with a PN532). Note that automatic port and driver discovery may disturb other serial devices and should only be used if that is not a concern.
  • New example tools use use the low-level driver API for very specific tasks like pure remote target discovery (with the option to do this repeatedly), listen to become discovered, and to simply observe when an external RF field is switched on and off (requires a PN531/2/3).
  • The tagtool.py and beam.py tools can inspect frequently encountered permission problems and output targeted recommendations for solving them.
  • Among other updates the documentation now gives more info about device capabilities on both the overview page as well as in the drivers section.

  • Fixes bug lp:1274973 "acr122 driver throws exception on frame length check"

0.9.1 (2014-02-13)

  • Fixes bug lp:1279271 "error reading type 1 tag with more than 120 bytes"

0.9.0 (2014-01-31)

  • First versioned release
