Example

.. code-block:: python

   import SomeLib.SomeCar.SomeModel as MyCar

   import udsoncan

   import isotp

   from udsoncan.connections import IsoTPSocketConnection

   from udsoncan.client import Client

   from udsoncan.exceptions import *

   from udsoncan.services import *

   

   udsoncan.setup_logging()

   

   conn = IsoTPSocketConnection('can0', isotp.Address(isotp.AddressingMode.Normal_11bits, rxid=0x123, txid=0x456))

   with Client(conn,  request_timeout=2, config=MyCar.config) as client:

      try:

         client.change_session(DiagnosticSessionControl.Session.extendedDiagnosticSession)  # integer with value of 3

         client.unlock_security_access(MyCar.debug_level)   # Fictive security level. Integer coming from fictive lib, let's say its value is 5

         client.write_data_by_identifier(udsoncan.DataIdentifier.VIN, 'ABC123456789')       # Standard ID for VIN is 0xF190. Codec is set in the client configuration

         print('Vehicle Identification Number successfully changed.')

         client.ecu_reset(ECUReset.ResetType.hardReset)  # HardReset = 0x01

      except NegativeResponseException as e:

         print('Server refused our request for service %s with code "%s" (0x%02x)' % (e.response.service.get_name(), e.response.code_name, e.response.code))

      except (InvalidResponseException, UnexpectedResponseException) as e:

         print('Server sent an invalid payload : %s' % e.response.original_payload)
