Diagnostic Client Library
Diagnostic Client Library
Welcome to Diagnostic Client library that is developed based on motivation taken from
Adaptive AUTOSAR Diagnostic Specification 21-11
Diagnostic Client library is developed according to the requirements needed on the diagnostic tester side.
Some internal APIs is implemented based on API Reference mentioned in
Adaptive AUTOSAR Diagnostic Specification 21-11
Overview
Diagnostic Client library acts as diagnostic tester library that is linked to a user application which wants to send
diagnostic
requests to multiple ECU over a network.
Diagnostic Client library supports below Diagnostic Protocols :-
- DoIP (Diagnostic over Internet Protocol)
- UDS (Unified Diagnostic Services)
Diagnostic Client library supports opening of multiple conversation(tester instance) for sending diagnostic request to
multiple ECU at the same time.
Documentation
The documentation of this project can be found here GitHub pages
Get Started
In this section, you will learn how to build and install
Diagnostic Client Library and also learn how to use diag-client-lib
Build and Install
In Linux :-
The following packages are needed to build and install Diagnostic Client library:-
| Package |
Usage |
Recommended version |
| CMake |
build system |
>=3.5 |
| COVESA DLT |
logging & tracing |
>= 2.18.8 |
| Boost |
asio operation |
>= 1.79.0 |
You can also execute to install dependencies :-
sh .github/setup.sh
In Windows :-
The following packages are needed to build and install Diagnostic Client library:-
| Package |
Usage |
Recommended version |
| CMake |
build system |
>=3.5 |
| Boost |
asio operation |
>= 1.79.0 |
Note: Covesa DLT is not directly supported in Windows. For more information
see Dlt Issue
How to use diag-client-lib
Diagnostic Client Library has to be linked first either statically or dynamically with executable before usage.
Diagnostic Client library can be built as shared library by setting the below CMake Flag to ON
BUILD_SHARED_LIBS : ON
Main instance of Diagnostic Client Library must be created using CreateDiagnosticClient method call by passing the
path to
diag-client config json file as parameter.
// Create the Diagnostic client and pass the config for creating internal properties
std::unique_ptr<diag::client::DiagClient> diag_client{
diag::client::CreateDiagnosticClient("etc/diag_client_config.json")};
diag-client config json file can be modified as per user
requirements.
Once Diagnostic Client Library is instantiated and initialized, GetDiagnosticClientConversation can be used to get the
tester/conversation instance
by passing the tester/conversation name.
// Get conversation for tester one by providing the conversation name configured
// in diag_client_config file passed while creating the diag client
diag::client::conversation::DiagClientConversation diag_client_conversation {
diag_client->GetDiagnosticClientConversation("DiagTesterOne")};
Multiple tester instance can be created using these method as provided in the configuration json file.
It also supports finding the available Diagnostic ECUs in the whole network through vehicle discovery.
// Create a vehicle info request for finding available ECU in the whole network,
// Use preselection mode `0` for broadcasting vehicle identification request to the whole network
diag::client::vehicle_info::VehicleInfoListRequestType const vehicle_info_request{0u, ""};
// Send Vehicle Identification request and get the response with available ECU information
diag::client::Result<diag::client::vehicle_info::VehicleInfoMessageResponseUniquePtr,
diag::client::DiagClient::VehicleInfoResponseError> const
vehicle_response_result{diag_client->SendVehicleIdentificationRequest(vehicle_info_request)};
Check the example application on how Diagnostic Client Library can be linked and used.
Example can be built too by enabling CMake Flag:-
BUILD_EXAMPLES : ON
Logging in diag-client-lib
Diagnostic Client Library supports logging and tracing by using the logging infrastructure
from COVESA DLT.
Logging is switched OFF by default using the CMake Flag, can be switched ON by enabling the flag:-
BUILD_WITH_DLT : ON
Note: DLT logging is not supported in Windows. So, CMake Flag must be switched OFF.
Documentation in diag-client-lib
Diagnostic Client Library uses doxygen to generate the documentation of the public api’s.
Doxygen build is switched OFF by default using the CMake Flag, can be switched ON by enabling the flag:-
BUILD_DOXYGEN : ON
In the future, we will have internal code documentation too.
Requirements
Component requirements implemented are documented REQ
Known Defect
- No defect is identified yet.
You can add new issues with label bug for notifying us about any defect in library.
Future Work
- Improve internal API documentation
- DoIP with TLS
For adding more features you can add new issues with label enhancement so that we can work on it.
