Trouble Shooting

Errors while concert start-up

Multiple Network Interface

It happens when multiple network interface(e.g- both wifi and wired) are up and running. Please set GATEWAY_NETWORK_INTERFACE environment.

Example:

 > export GATEWAY_NETWORK_INTERFACE=eth0

Running Concert and Robot Client in the same pc

Concert is a multi master system which provides centralised workspace for multiple ROS instances(e.g robot). So Each concert and robot client require to use different ROS_MASTER_URI.

For example,

Concert

 > export ROS_MASTER_URI=http://localhost:11311
 > roslaunch my_concert concert.launch  

Client

 > export ROS_MASTER_URI=http://localhost:11312
 > roslaunch my_robot robot_bringup.launch

Note that rocon_launch is a convenient tool to start multiple ros masters. Check this out.

TODOs

• Client Blacklisted
• Concert Blacklisted

If you don't find your need..

• Please ask on ROS Answers with rocon tag.
