I just got my hands on a nodemcu v3 Lolin. Great little device. Was just wondering if it's possible to somehow force disable the blue led? (I would prefer a software way)
I created a webserver and with a every single incomming request I get a blink which can be very distracting in dark areas.

Thanks,
Alex

It would appear that if the schematic above is correct, that GPIO 16 (D2) is the source for the LED blinking.

The blinking LED is often used for diagnostic purposes and status info. Unless you intend on dedicating the NodeMCU to your current project, just use a bit of black electrical tape to mask the blink. I have been known to use black fingernail polish, too.
