However, at the time there was almost no English-language documentation on the chip and the commands it accepted.The very low price and the fact that there were very few external components on the module which suggests that it could eventually be very inexpensive in volume, attracted many hackers to explore the module, chip, and the software on it, as well as to translate the Chinese documentation. This small module allows microcontrollers to connect to a Wi-Fi network and make simple TCP/IP connections using Hayes-style commands. The chip first came to the attention of western makers in August 2014 with the ESP-01 module, made by a third-party manufacturer, AI-Thinker. The ESP8266 is a low-cost Wi-Fi chip with full TCP/IP stack and microcontroller capability produced by a Shanghai-based Chinese manufacturer, Espressif Systems. Now it’s time to have some fun with the ESP8266 In the last post, we talked about AT commands and how they’re used to interact with the ESP8266 more specifically, how they’re used to interact with its stock firmware.But if you remember, AT commands are only used for wireless functionalities.To take advantage of the chip’s really cool general purpose input/output (GPIO) pins, or some. ![]() Connecting the ESP8266 Wi-Fi module to Arduino. ![]()
