Crash of remocon if paired robot is not up #22

Closed stonier closed 11 years ago

stonier commented 11 years ago

This is a new bug I just introduced (good at that!). Crashes after trying to look for non-existant robot.

In master checker:

// this line of code causes a background thread to perpetually crash and restart if there is no master uri.
nodeMainExecutorService.execute(client, nodeConfiguration.setNodeName("platform_info_client_node"));

What is a good way of checking if the master is up?

Look for rosversion param.
