v1.15

New functionality

• #110 : Support new subfunctions for ReadDiagnosticInformation (0x19) (tests : kayoub5, yassin92)
  • reportDTCExtDataRecordByRecordNumber (0x16)
  • reportUserDefMemoryDTCByStatusMask (0x17)
  • reportUserDefMemoryDTCSnapshotRecordByDTCNumber (0x18)
  • reportUserDefMemoryDTCExtDataRecordByDTCNumber (0x19)

v1.14

Features:

• Added support for J2534 passthru (#75, #76) [credit: @joeFischetti ]
• Added possibility to send data bytes when requesting a seed with SecurityAccess service (#79) [credit : @guigor]
• Added a parameter to disable the global timeout when sending a request, meaning it is now possible to wait indefinitely for a response if the server ask to wait continuously. (#73, #86) [credit: @martinjthompson ]
• Added support for DynamicallyDefineDataIdentifier service (#78)

Bugfix :

• Start receive timer after call to the connection send to avoid timing out while transmitting long payload (#43, #68) [credit: @wanam ]
• RequestFileTransfer response now properly parse the filesize (#89, #90) [credit: @trivialpursuer ]

v1.13.1

New feature:

• InputOutputControlByIdentifier service now support variable length DID with (Codec.ReadAllRemainingData). Fixes #57
• Added a parameter to change the standard version support (2006, 2013, 2020).
• When using version 2013 or 2020, DiagnosticSessionControl now requires the server to provides timing requirement (fixes #53)
• Added a parameter to ignore server timing parameters when doing a DiagnosticSessionControl (for 2013 and 2020 version).

Bugfixes:

• Fixed a typo in error code. IncorrectMessageLegthOrInvalidFormat becomes IncorrectMessageLengthOrInvalidFormat

Minor:

• Changes few logging details.

v1.12.2

Bugfix

• Fixed #51. Unlocking a security level that is already unlocked (seed=0) is now handled properly. No key is sent to the server and a positive response is returned to the user.

v1.12.1

Bugfix

• Fixed #50 : Correctly encode filename length on 16bits instead of 8bits in RequestFileTransfer

v1.12

New feature

• #49 : Security level now passed to the security algorithm when using client.unlock_security_access. For backward compatibility, parameters are now given as named parameter. Only the parameters present in the algorithm signature will be passed. See the below snippet of code

    algo_params = {}
        try:
            algo_args =  self.config['security_algo'].__code__.co_varnames[:self.config['security_algo'].__code__.co_argcount]
        
            if 'seed' in algo_args:
                algo_params['seed'] = seed
            if 'level' in algo_args:
                algo_params['level'] = level
            if 'params' in algo_args:
                algo_params['params'] = params
        except:
            algo_params = {'seed':seed, 'params' : params, 'level' : level}
  
    key = self.config['security_algo'].__call__(**algo_params)
  

v1.11

#47 - Now support RequestFileTransfer service

v1.10

#New feature (#45). Allow the user to make a DidCodec that read a whole payload even if not dictated by ISO-14229.

v1.9

New feature:

• Resolved #37 - Now possible to use client.payload_override to send arbitrary payloads and still take advantage of the client capacity of analyzing a malformed response. See https://udsoncan.readthedocs.io/en/latest/udsoncan/client.html#overriding-the-output

v1.8.1

Bug fix

• #22 : Trying to use a closed connection will trigger the right Exception

Enhancement

• #29 : Now possible to use write_data_by_identifier with multiple values without specifying a custom codec
• #35 : Indentation switched to spaces instead of tabs
• Fixed several typos or erroneous error messages
