someipy Daemon

The someipy daemon is a background process responsible for managing all communication with the SOME/IP network, including service discovery. Applications using the someipy library do not need to handle network communication directly, as the daemon manages these complexities. A single daemon instance should be running per ECU or PC. Applications interact with the daemon via Unix Domain Sockets (UDS).

Starting the Daemon

The someipy daemon can be started from the command line. After installing the library with pip3 install someipy, the someipyd command becomes available in your system’s PATH.

To start the daemon, simply run:

someipyd

Optionally, you can specify a path to a configuration file using the –config argument:

someipyd --config /path/to/config.json

The configuration file is a JSON file that allows you to customize the daemon’s behavior. The following fields are available and all are optional:

{
    "sd_address": "224.224.224.245",
    "sd_port": 30490,
    "log_level": "DEBUG",
    "interface": "127.0.0.2",
    "log_path": "/var/log/someipy.log",
    "use_tcp": false,
    "tcp_host": "127.0.0.1",
    "tcp_port": 30500

• sd_address: The multicast address for Service Discovery.

• sd_port: The port for Service Discovery.

• log_level: The logging level (e.g., DEBUG, INFO, WARNING, ERROR).

• interface: The network interface to bind to.

• log_path: The path to the log file.

• use_tcp: Whether to use TCP sockets instead of UDS sockets for communication between the daemon and clients. If Windows is used use_tcp must be set to true.

• tcp_host: The host address for TCP communication (only relevant if use_tcp is true).

• tcp_port: The port for TCP communication (only relevant if use_tcp is true).
