ESP8266 NodeMCU – IDE

Three Different IDE’s are available from NodeMCU ESP8266 Platform

• ESPlorer
• Lua Loader
• ESP8266 Web File Manager
• ESP-IDF

This ESP8266 NodeMCU IDE tutorial Only discussed ESPlorer, You can use this ESPlorer tool as a UART Terminal Application. You can send and receive the data in terminal windows like Putty, DockLight

ESPlorer IDE

• ESPlorer is Java-based a wonderful user interface IDE for developers of (ESP8266 chips) NodeMCU, MycroPython, AT-Based, RN2483 development.
• It’s fully written in Java.

Getting Started with ESPlorer IDE

First Watch this Video tutorial

Step to Follow

• Open ESPlorer IDE
• The serial port chooser may be blank When ESPlorore initially.
• Click  Scan system for available serial port
• Plug your ESP866 Programmer Setup with your computer
• Now click, Scan System for available serial port
  • Check if the ‘COM’ port is enabled or not in the Device Manager on the PC, especially when the COM Port is not detected.
    • Open Device Manager(Windows + X)Check COM Port is enabled
      • If not enabled check the resonIf enabled note that COM port number and again scan in ESPlorer IDE.

    If COM Port detected  then it will shows that COM port number.

• Select correct Baud rate (try 9600,57600, 115200)
• “Open” Select Serial Port
  • Showing “PORT OPEN 9600” (eg Buad rate :9600)
  • showing “Communication with MCU..“
• now try any library functions
  • Eg: node.heap(), node.chipid()
