Problem NodeMCU ESP8266

Projects Programming
1

Hi
I am working with a NodeMCU esp2866 board, I did all the necessary configuration to program through the Arduino IDE software, the programs are uploaded 100% correctly but when the NodeMCU is loaded it does nothing. What could be happening?
Thank.

What are you expecting it to do ?

What sketch are you loading and how would you know that it is working ?

Try this sketch


void setup()
{
  Serial.begin(115200);
}

void loop()
{
  static byte x = 0;
  Serial.println(x++);
  delay(1000);
}

Set the baud rate of the Serial monitor to 115200. Does anything print on the Serial monitor ?

I set the serial monitor to 115200 but it shows nothing

4

What messages do you get when you upload the sketch ?

5

It appears to me that the program is uploaded and below it says
Leaving...
Hard reset via RTS pin...

6

That sounds OK

Which board have you got selected in the IDE and which IDE version are you using ?

7

It has worked for me, I just disconnected and reconnected the board. Why is this happening?

8

you can not turn it off, just press the reset button

9

It doesn't work when I press the reset button.

after pressing the reset button, close and reopen the port monitor

Thanks, but it still doesn't work, I tried another board and it works correctly, is there a way to repair it?
