title: What should ESP.restart() exactly do in NodeMCU?
body: <p>What should <code>ESP.restart()</code> exactly do in NodeMCU? I want to redo my sketch, but after using <code>ESP.restart()</code> I'll get this in the terminal:</p>
  <blockquote>
  <p>ets Jan  8 2013,rst cause:2, boot mode:(1,6)</p>
  <p>ets Jan  8 2013,rst cause:4, boot mode:(1,6)</p>
  <p>wdt reset</p>
  </blockquote>
  <p>And after that nothing happens. So how can I redo my sketch like using RST button of NodeMCU?</p>
