title: Blue light on NodeMCU Esp8266 doesn't blink
body: <p>The blue light on this Esp8266 used to flash blue when plugged in. Now it flashes once when plugged in then not at all. After running the flasher <a href="https://github.com/nodemcu/nodemcu-flasher" rel="nofollow noreferrer">https://github.com/nodemcu/nodemcu-flasher</a> to try to wipe the memory (thats what that does right?) and the light flashed while the flasher worked in the background then stopped once again completely. (I know i'm using the word flash alot).</p>
  
  <p>I'd just like to make sure the data is wiped clean from my NodeMCU Esp8266 so that I can upload new programs to it. Currently thinking it may have been since the blue light stopped flashing and all other functionality seems bleak. Does any one have any idea wha this means? </p>
  
  <p><strong><em>Update</em></strong> I admittedly tried uploading several projects onto it without making sure everything was still good to go. </p>
