NodeMCU successfully compiled and uploaded a simple blink sketch on board, no errors at all, but the LED stays on constantly and does not blink. Also I have checked the power is enough. I have checked this with all pins but the red LED only stays on and doesn't blink. I have no idea what could have gone wrong. And how to fix this?

Fixed it.... turns out that in the tools, the board was selected to be NodeMCU 0.9 when it should actually have been NodeMCU 1.0 so i just changed it to NodeMCU 1.0 and it worked!
