Dear All,

I setup a system on my odroid and made few nodes to test it. I did the settings so that the nodes are launched by the Master on system boot up. Yesterday when I turned on my odroid , I could see all the five nodes after I typed in rosnode list on the terminal. Today when I booted my Odroid, and typed in rosnode list, I couldn't see the five nodes. Instead I am getting this error message .

Unable to communicate with master

That would be great if someone explain it to me what might be the problem. and what's the solution.

It sounds like your automatic startup script isn't working. Without knowing how you set up the automatic startup it's impossible for me to give any more specific guidance.
