Read/Write Data By Identifier Example

UDS client and server demonstrating Read Data By Identifier (0x22) and Write Data By Identifier (0x2E) services.

Overview

This example shows how to implement RDBI/WDBI services for reading and writing data identifiers on a UDS server, along with a corresponding client that exercises these services.

• examples/linux_rdbi_wdbi/client.c - Client implementation demonstrating RDBI/WDBI requests

Features Demonstrated

• Reading data identifiers (0x22)
• Writing data identifiers (0x2E)
• Data identifier handlers
• Client request sequences

Building

See the main repository README for build instructions.

Running

Requires a CAN interface (virtual or physical) with ISO-TP support.

# Terminal 1: Run server
./linux_rdbi_wdbi_server vcan0
