Green LED is on while NodeMCU is connected to a wifi network.
Green LED stays on for a very short interval when uploading frames to web as it finishes very fast. This may cause a misconception. Was it on while the wifi connection or it just blinked.
Blue LED stays on when serial communication between NodeMCU and Arduino Mega fails.
