SOME/IP Server Demo
There is an example implementation of SOME/IP server demo available in apps folder. SOME/IP server is in waiting condition for UDP socket connection .Once connected SOME/IP server is ready to send the response to the client.
The below diagram captures the high level flow of client and server of SOME/IP.
Service Discovery Process
Notification Process
In this implementation, a model ECU is created to mimic various features that hold vehicle information like speed, RPM, door state, and gear state. Based on the SOME/IP protocol, if any event group is subscribed to by a client, the notification events will be sent while fields are updated in the corresponding event group, and data will be read and written on particular events(under subscribed eventgroup) with the below-mentioned event IDs.

Note: The log level uses individual bits to enable or disable specific log categories. Each log type corresponds to a bit position (RS_LOG_ERR → bit 0, RS_LOG_INFO → bit 1, RS_LOG_DEBUG → bit 2, RS_LOG_RX → bit 3, RS_LOG_TX → bit 4).
For example, log level = 1D (binary 11101) means that the 0th, 2nd, 3rd, and 4th bits are set, so ERR, DEBUG, RX, and TX logs are enabled, while the INFO log (bit 1) is disabled.
After project successfully built, someip_server_demo binary generated.
Open the terminal in the above folder and run the below command
Windows (IPV6)
The SOME/IP server initiates the process and waits for the client to connect. After the SOME/IP client starts the process, both the server and client connects and proceed with services.
Refer to the SOME/IP protocol page for more details SOME/IP Protocol.
