Since the ESP8266 AT v2.0, we implement the AT firmware based on the new IDF style
ESP8266_RTOS_SDK. Some of the AT commands are different with the old ESP8266 NonOS AT.
Considering these major changes may cause significant impact on existing projects, it's recommended that
this version is only used for the implementation of new projects, instead of being used as an upgrade
for any existing mass-production projects.
To run the ESP8266 AT, you can download the binary in ESP8266-IDF-AT/factory to address 0x0. The
ESP8266 IDF AT sends AT commands through the following pins.
GPIO13 is RXD
GPIO15 is TXD
GPIO1 is RTS (Optional)
GPIO3 is CTS (Optional)
We will keep maintaining the old ESP8266 NonOS AT (bug fix only) for a certain but long term. But for the
new AT customers, it is suggested to use the new ESP8266 IDF AT.
