There are three main types of firmware and development systems available for the ESP8266. For more on the ESP8266 Huzzah board see this posting. Most of the low cost modules are not breadboard friendly, don’t have an onboard 3.3V regulator or level shifting for signals. It makes it much easier to use with the Raspberry Pi than the really cheap modules. The Adafruit ESP8266 Huzzah board is a great breakout for the ESP8266. And they are all struggling to make it as inexpensive as the ESP8266

Now all the major players are working on inexpensive versions of an IOT chip with WiFi connectivity. They are a fabless semiconductor company that just came out of nowhere and shook up the whole industry. The ESP8266 is made by a privately held company in China called Espressif. Update: Ways of making the ESP8266 operate more reliably in the AT Command Mode. We are using the Adafruit ESP8266 Huzzah breakout board for these postings.Īs you will see below, the AT firmware experience was not good.

In this posting we are showing how to use the AT Command set firmware with the ESP8266. This is the fourth of a multi-part posting on the ESP8266. IOT ESP8266 Tutorial – AT Command Set Firmware
