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

SOME/IP Discovery process Sequence Diagram

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.

Following Event IDs are available in the example:

Supported structure based event information read/write
Service ID	Instance ID	Eventgroup ID	Event ID	Size	Read/Write	Description
0x1234	0x5678	0x4425	0X8777	44 Byte	Read Write	Fields in structure Vehicle’s name Vehicle’s power factor vehicle’s RPM vehicle’s speed vehicle’s ODO value

Supported Event IDs
Service ID	Instance ID	Eventgroup ID	Event ID	Size	Read/Write	Description
0x1234	0x5678	0x4465	0x8776	1 Byte	Read Write	Speed Level from 0 to 200
0x1234	0x5678	0x4465	0x8778	1 Byte	Read Write	Gear Value from 0 to 5
0x1234	0x5678	0x4425	0X8779	1 Byte	Read Write	Door state Value from 0 to 1

Supported Method IDs
Method ID	Description
0x427	Method ID used to Read the value of Event ID
0x428	Method ID used to Write the value of Event ID

Read data by Event ID (0x427) service

Few Event IDs are supported in the demo where many of them are automatically incrementing so that it can be read to find the differences.

Write Data By Event ID (0x428) service

Event ID specified as Read/Write are allowed to be written

SOME/IP Server Running Example

Refer to the Supported Platforms page to setup your environmental setup and follow further.

User Configuration for Server

Server Configuration
Socket configuration	Value
SOME/IP server IP address	IP address of server running PC or machine
SOME/IP SD Port	30490
SOME/IP server Port number	30509

After project successfully built, someip_server_demo binary generated.
Open the terminal in the above folder and run the below command

Linux

$ ./someip_server_demo

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.
