- Sat Jul 30, 2016 2:46 pm #51790 Hi every body

I would like to play with NodeMCU Board :



Should i use special instruction to get it work ? not same as ESP-07 ?

I tried OTA Basic example , with esp8266 board .

Why sould i use NodeMCU board ? What is difference between them ?

I tried to connect my FTDI device to send binary , but failed.

I don't want to write code in lua .

Thanks for help.

Use: ESP8266 ESP-07 ESP-12F ESP-14
Windows 10
Arduino IDE 1.6.13
ESP8266 2.3-RC-2 + git ESP8266 core

I 've got 3 NodeMCU Board,
First does not work properly :

- Sat Jul 30, 2016 4:30 pm #51800 Finally, It was just a problem of power supply .
All of them works fine,
I can use Arduino IDE as i wish.

Sorry for disturbing.
