- Sun Oct 23, 2016 10:10 am #56983 For users programming via the ArduinoIDE, you would do something like this somewhere in setup()

Code: Select allSerial.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.

- Mon Oct 24, 2016 5:16 pm #57065 I'm using ArduinoIDE 1.6.9 and it gave me error...

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

- Tue Oct 25, 2016 2:19 pm #57108 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 allextern "C" {
#include "user_interface.h"
}
