Layang ODDS

Public documentation and release notes for Layang ODDS, an OpenDDS Simulator desktop workflow for DDS topic discovery, IDL mapping, DDS Listener/Dynamic subscription, JSON publishing, scenario streaming, and per-topic QoS checks.

Layang ODDS is designed to help developers, integrators, and DDS users test OpenDDS topic flows from a desktop application.

See Download release for release download and install notes.

OpenDDS Environment

Layang ODDS can read OpenDDS settings from two env files. Use the user config for normal desktop usage, or system-wide config for shared/admin-managed machines. No manual shell export is required when launching the packaged app.

Option 1: User config, recommended

mkdir -p ~/.config/layang-odds
nano ~/.config/layang-odds/env

Example content:

OPENDDS_ROOT=/opt/OpenDDS-3.29.1
LAYANG_ODDS_DDS_CONFIG=$HOME/.config/layang-odds/rtps.ini

Option 2: System-wide config

sudo nano /etc/layang-odds/layang-odds.env

Example content:

OPENDDS_ROOT=/opt/OpenDDS-3.29.1
LAYANG_ODDS_DDS_CONFIG=/home/rocky/.config/layang-odds/rtps.ini

After changing an env file, restart Layang ODDS and run DDS Runtime Build again if the workspace IDL or runtime sidecar needs to be refreshed.

See OpenDDS environment for the full guide.
