I bought nodemcu devkit 1.0. After learning basic functions of lua loader.

I started to write and upload simple codes for controlling GPIO pins, and then move to other advanced codes.

1.So, I wrote this simple code for LED blink and didn't work.
while 1 do
gpio.write(4,gpio.HIGH)
tmr.delay(10000)
gpio.write(4,gpio.LOW)
tmr.delay(10000)
end


2.I get these messages when connecting the chip, are they OK?


Connected to COM2 at 9600 baud

2. Also tried esplorer, do not upload the code, can't detect the device.
3. Arduino IDE, nothing is working.
