Release v0.1 -- February 22nd, 2014

The ndef modules provides methods for creating and parsing messages and records in the NDEF format according to NFC Forum technical specification. Its main purpose is to provide comprehensive verification of raw NDEF messages. It can be used to verify messages before writing them to an actual tag.

Available on PyPI.

>>> import ndef >>> message_data = 'D1010F5402656E48656C6C6F20776F726C6421'.decode('hex') >>> message = ndef.NdefMessage(message_data) >>> record = message.records[0] >>> record.tnf 1 >>> record.type 'T' >>> record.id >>> record.payload 'x02enHello world!' >>>

>>> import ndef >>> message_data = '9901050155610123456761'.decode('hex') >>> message = ndef.NdefMessage(message_data) Traceback (most recent call last): File "<stdin>", line 1, in <module> File "ndefndef.py", line 274, in __init__ self.verify() File "ndefndef.py", line 278, in verify self._verify_begin_end() File "ndefndef.py", line 296, in _verify_begin_end raise InvalidNdefMessage("last record's ME flag is off") ndef.ndef.InvalidNdefMessage: last record's ME flag is off >>>

>>> import ndef >>> text_record = (ndef.TNF_WELL_KNOWN, ndef.RTD_TEXT, 'id', 'hello world') >>> text_message = ndef.new_message(text_record) >>> text_raw_ndef = text_message.to_buffer() >>> text_raw_ndef.encode('hex') 'd9010b0254696468656c6c6f20776f726c64' >>>
