[Android Software Development] Nikhil:
I'm using it at home.

I tried what you said. I connected to 3G, surfed for a while. Then connected RT tool. It worked at first but now it is not working even if I connect to 3G and then connect with tool.

I rebooted device, restarted tool, re-established connection, did all things but it is not working.

May be you should see log.
