ESP8266 NodeMCU – IDE


Three Different IDE’s are available fro NodeMCU ESP8266 Platfom

  • ESPlorer
  • Lua Loader
  • ESP8266 Web File Manager


ESPlorer IDE

  • ESPlorer is java based a wonderful user interface IDE for developers of (ESP8266 chips) NodeMCU, MycroPython, AT-Based, RN2483 development.

Getting Started with ESPlorer IDE

 

First Watch this Video tutorial

 

 

Step to Follow

  • Basic Connection Diagram (Refer the above image)
  • Open ESPlorer IDE
  • When opened ESPlorer shows Serial port chooser may be blank.
  • Click  Scan system for available serial port
  • Plug your ESP866 Programmer Setup with your computer
  • Now click, Scan system for available serial port
    • If COM Port not detected, then check COM port is enabled in Device manager
      • Open Device Manager(Windows + X)
      • Check COM Port is enabled
        • If not  enable check the reson
        • If 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()

ESPlorer Troubleshoot

file  not upload?

  • if file contains nothing or data not there inside, its should not upload, and show status “BUSY

 

Not Enough memory?

  • ESP8266 will get error when you continuously printing something or continuously running a some function

 

Communicating with MCU?

  • It’s not a error. its a status, try some NodeMCU library function further [Ex: node.heap()]
  • Try different baud rate [9600, 57600, 115200]

 

COM Port Not Detected

  • Check your USB to TTL/Serial Programmer connection
  • Make Sure COM port is Enabled in [Windows + X] Device manager (if Disabled do manually install the driver)

 

Could not find the main class. ESPlorer cant run program will exit

  • Please install or reinstall java SE version 7 and above.

 

Can’t auto-detect firmware, because proper answer not received (may be unknown firmware).

 

Getting  something chunk like this  ëÕ½ou}¯­íë=nogy‰«ax(©íê=ëë—.låax(©íê

  • Please change correct baud rate of UART (try : 9600, 57600, 115200)
  • Check the UART Connection TX, RX pins
