Loading IDE 1.6.11 on to computer that's not on the internet.

I downloaded IDE 1.6.11 from Arduino.cc to a thumb drive.
I also installed all my libraries into documents\arduino.
Everything worked just fine after I installed it to the desktop of a computer that's not on the internet.
I experimented with a few programs that I load to a UNO and had no problems.

But, here's the problem, absolutely nothing to do with ESP8266 boards is available.
Not generic or Adafruit Huzza.

I have been playing with this for over three hours with no success.

What am I doing wrong ?

You need to install the ESP8266 boards via Boards Manager. Unfortunately that requires internet access. Here's my advice:

  • Create a folder named portable in the Arduino IDE installation on the thumb drive. This will cause the IDE to run in portable mode.
  • Run the Arduino IDE on a computer with internet access.
  • File > Preferences > Additional Boards Manager URLs: > http://arduino.esp8266.com/stable/package_esp8266com_index.json > OK
  • Tools > Board > Boards Manager > esp8266(click on it) > Install
  • After installation completes click the "Close" button.

The ESP8266 boards have now been installed to the thumb drive and should be usable from your non-internet connected computer.

Thanks pert.

I will try your suggestion shortly.

Thank you very much pert.

I followed your instructions and it worked perfectly.
