Update Esp8266 with new firmware

#1

Hi everyone,

Matt mentioned the ability to update the firmware on an Esp8266 device over the internet.
I was wondering if this is an easy enough process.

I simply need to change one line of code. I have checked it on one device, now need to update the rest.
How to I upload a new sketch (built in the arduino IDE) to devices without having to plug them into my computer.

You’ll need the ArduinoOTA library to upload over the network, the ESP and the computer must be connected to the same network.
Read this article, this helped me a lot.
