2 years ago This question is better suited to the udsoncan project as DID's are not DoIP related. But from what I recall there is no such service in UDS. You're only options are to: 1) Know the DIDs because you're the OEM and the define the config struct accordingly 2) Have access to a definition file like ODX which defines these things in a machine readable format 3) Fuzz the network and figure out from the errors what ID's are valid in any given session and what their buffer sizes are

Hi Jacob, i don't know how to scan DID with DoiPClient library. I use this piece of code:
from doipclient.connectors import DoIPClientUDSConnector from udsoncan.client import Client, Request
uds_client = Client(uds_connection) with Client(uds_connection, request_timeout=2) as client: try: client.read_data_by_identifier_first([0xF190]) 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) and when I run this script I 've this error: [ConfigError] : Actual data identifier configuration contains no definition for data identifier 0xf190 [ConfigError] : Actual data identifier configuration contains no definition for data identifier 0xf190
For me that normal, because I've don't initiate the config dictionnary with right parameters for this record.
But my aim is to discovers services and DID in UDS so how to define something I don't know at the beginning ?
So if you can help me ? many thanks by advance :)
