[BUG]: Facing an issue in while communicating between host and virtual machine

[DharaniAllada]

vSomeip Version

v3.4.10

Boost Version

1.71

Environment

Ubuntu 20.04.6

Describe the bug

The Problem statement i have to do is " Automate client server communication between the host PC and QEMU using SOMEIP. Validate the communication using wireshark."

So from the starting the steps i followed are:

sudo apt install cmake git gcc g++ libboost-system-dev libboost-thread-dev libboost-log-dev libboost-chrono-dev libboost-date-time-dev libboost-atomic-dev libboost-program-options-dev git clone https://github.com/GENIVI/vsomeip.git cd vsomeip mkdir build cd build cmake .. make sudo make install

In the host machine i wrote the client code and vsomeip.json under the vsomeip/examples

client-sample.cpp: :

include <vsomeip/vsomeip.hpp>

include

include

define SAMPLE_SERVICE_ID 0x1234

define SAMPLE_INSTANCE_ID 0x5678

define SAMPLE_METHOD_ID 0x0421

class Client { public: Client() : app_(vsomeip::runtime::get()->create_application("Client")) {}

        bool init()
    {
            if(!app_->init()) {
            std::cerr << "Failed to initialize application" << std::endl;
                    return false;
            }

            app_->register_message_handler(
                    SAMPLE_SERVICE_ID, SAMPLE_INSTANCE_ID, SAMPLE_METHOD_ID,
                    std::bind(&Client::on_response, this, std::placeholders::_1));

            return true;
        }

        void start()
    {
        std::cout << "Client application started and initialized." << std::endl;
            app_->request_service(SAMPLE_SERVICE_ID, SAMPLE_INSTANCE_ID);
            std::shared_ptr<vsomeip::message> request = vsomeip::runtime::get()->create_request();
        std::cout << "Sending request to service" << std::endl;
            app_->send(request);
            app_->start();
        }

        void stop()
    {
            app_->stop();
        }

private:
        void on_response(const std::shared_ptr<vsomeip::message> &_response)
    {
            std::shared_ptr<vsomeip::payload> payload = _response->get_payload();
            vsomeip::length_t length = payload->get_length();
            const vsomeip::byte_t* data = payload->get_data();

            std::vector<vsomeip::byte_t> response_data(data, data + length);
            std::string response_string(response_data.begin(), response_data.end());

            std::cout << "Received response: " << response_string << std::endl;
        }

        std::shared_ptr<vsomeip::application> app_;

};

int main() { Client cli; if (cli.init()) { cli.start(); }else { std::cerr << "Failed to initialize client application" << std::endl; } return 0; }

vsomeip.json :

{ "unicast": "Ip address of my host machine which is in network interface virbr0", "logging": { "level": "info" }, "applications": [ { "name": "Client", "id": "0x5678" } ], "services": [ { "service": "0x1234", "instance": "0x5678", "unreliable": { "port": 30509 }, "reliable": { "port": 30510 } } ], "service-discovery": { "enabled": true, "multicast": "244.0.0.1", "port": 30490 } }

Now in VM : i followed the steps

sudo apt install cmake git gcc g++ libboost-system-dev libboost-thread-dev libboost-log-dev libboost-chrono-dev libboost-date-time-dev libboost-atomic-dev libboost-program-options-dev git clone https://github.com/GENIVI/vsomeip.git cd vsomeip mkdir build cd build cmake .. make sudo make install

and later in vsomeip/examples i wrote :

service-sample.cpp:

include<vsomeip/vsomeip.hpp>

include

include

define SAMPLE_SERVICE_ID 0x1234

define SAMPLE_INSTANCE_ID 0x5678

define SAMPLE_METHOD_ID 0x0421

class Service { public: Service() : app_(vsomeip::runtime::get()->create_application("Service")){}

    bool init() {
        if(!app_ -> init()) {
            std::cerr << "Failed to initialize application" << std::endl;
            return false;
        }

        app_ -> register_message_handler(
            SAMPLE_SERVICE_ID, SAMPLE_INSTANCE_ID, SAMPLE_METHOD_ID,
            std::bind(&Service::on_message, this, std::placeholders::_1));

        return true;
    }

    void start() {
        std::cout << "Service application started and initialized" << std::endl;
        app_ -> start();
    }

    void stop() {
        app_ -> stop();
    }

private:
    void on_message(const std::shared_ptr<vsomeip::message> &_request) {
        std::cout << "Received message and sending response..." << std::endl;
        std::shared_ptr<vsomeip::message> response = vsomeip::runtime::get() -> create_response(_request);
        response -> set_payload(vsomeip::runtime::get() -> create_payload());
        app_ -> send(response);
    }

    std::shared_ptr<vsomeip::application> app_;

};

int main() { Service srv; if(srv.init()) { srv.start(); } else { std::cerr << "Failed to initialize service application" << std::endl; } return 0; }

vsomeip.json:

{ "unicast": "Ip address of vm which is in network interface enp1s0", "logging": { "level": "info" }, "applications": [ { "name": "Service", "id": "0x1234" } ], "services": [ { "service": "0x1234", "instance": "0x5678", "unreliable": { "port": 30509 }, "reliable": { "port": 30510 } } ], "service-discovery": { "enabled": true, "multicast": "244.0.0.1", "port": 30490 } }

Now while running the cpp file in VM showing the log like:

i think there might some error there in finding the service can any one please help me with this

Do your ever call to offer_service to actually offer your service to the client? From the log it seems you do not.

@DharaniAllada is this still an issue from your side?
