EasyOTA

ESP Easy firmware can be upgraded using OTA (Over The Air). So instead of using the serial port and a direct connection to the ESP, you can use the Wifi connection to remote units.

From within the Arduino IDE we will export the binary file so it can be uploaded using the ESP Easy webgui.

When the Arduino IDE has finished, locate your sketch folder (where the ESP Easy source files are located).

It should contain this file: ESPEasy.cpp.nodemcu.bin

From menu tools, select the firmware load button

Locate the bin file:

And press the update button.

In a short while it will show a short message "ok" in your web browser.

Now give the ESP 10 to 20 seconds to restart and connect again to your network.

Check the main page and verify that the build number corresponds to the bin file just uploaded.
