Serial DLT Hub

serial-dlt-hub is a tool that provides a TCP network interface, allowing multiple clients to connect and interact with multiple serial devices that offer a DLT (Diagnostic Log and Trace) interface. By acting as a bridge between network clients and serial DLT sources, it enables multiple consumers to access DLT messages from serial devices that would otherwise only support a single consumer.

Features

• Supports connecting to multiple serial ports to receive DLT messages
• Allows multiple clients to connect via TCP
• Forwards all received DLT messages to every connected TCP client
• Each DLT message received from a serial device is updated to include an ECU ID
• ECU IDs of DLT messages can be configured individually for each device
• DLT commands received from clients are forwarded to the appropriate serial device if the command includes the configured ECU ID

Usage

1. Create configuration:

   All parameters are configured via a configuration file. The following shows an example:

   [network]
   # Network interface and port for incoming TCP connections
   addr = "0.0.0.0:3490"
   
   # Serial device configuration for device1
   [serial.device1]
   # ECU ID to assign to DLT messages from device1
   id = "DEV1"
   # Path to the serial port for device1
   device = "/dev/ttyUSB0"
   # Baud rate for the serial connection
   baudrate = 115200
   
   # Serial device configuration for another device
   [serial.device2]
   id = "DEV2"
   device = "/dev/ttyUSB1"
   baudrate = 115200

2. Run the hub:

   By default, the hub searches for a configuration file named config.toml in the current working directory. You can specify a different configuration file using the --config command-line argument:

   serial-dlt-hub --config path/to/your-config.toml

   Use --help to see all available options.
