Tinypilot... I happen to have one here as well. Connect to it with an ssh client as user tc, default password pypilot. To shut it down, use sudo sv stop pypilot. In attached trace you will see the same serial probe which eventually leads to a serialprobe success, meaning he can talk to the arduino. Mind you that I have a fixed ip address; you might still have the defaultĀ 192.168.14.1, I believe.
EDIT: if it is tinypilot there's less that could have been done wrong. The test for a signal on the nano's tx pin is crucial. Make sure you put a resistor in series with the led ok?
