How to easily Firmware Update the AI Thinker ESP8266

This is not just another post of how to connect Arduino UNO to ESP8266 board.

Yes there is how to connect it and how to configure it in details. Also, in this post you can find the detailed steps of how to firmware update of the ESP8266 board.



This firmware update is essential for some boards to have the function of AT commands.



Why

ESP8266 is a smart solution for many IoT projects indeed. It's so cheap and powerful that you can start prototyping and making your own products quickly.

ESP8266 is based on the ARM processor and Arduino compatible. It also has its own Wifi transceiver.

So you can use it as a stand alone Arduino board with Wifi capability and you can also use it as an Arduino Wifi Shield.

The problem is when you get the AI-Cloud inside version of ESP8266 you need to Firmware Update it before using the AT commands.

This means that you can use it only as a standalone Arduino board before the update.

But to be able to use it as an Arduino Wifi Shield with AT command you have to update the firmware.

Got it ?
