For users programming via the ArduinoIDE, you would do something like this somewhere in setup()

Code: Select all

Serial.printf("\n\nSDK version:%s\n\r", system_get_sdk_version());

Remember, the AT firmware is overwritten when the ArduinoIDE is installed; essentially there are two parts: the user's compiled sketch and the ESP8266 binary firmware to support the low-level API calls. If one wishes to restore the AT firmware, it must be uploaded using one of the several flash firmware programs.

I'm using ArduinoIDE 1.6.9 and it gave me error...

This one works Serial.println(ESP.getSdkVersion());

Yes, because ESP.getSdkVersion() is a C++ function, while system_get_sdk_version() is a plain C that requires to include prototype from SDK the following way :

Code: Select all

extern "C" {
#include "user_interface.h"
}
