As soon as the flashing process starts, the tool will display two MAC Addresses as AP and STA and also displays the information about Module in the DETECTED INFO section. The ESP8266 Module comes with an AT Command Firmware and the Firmware files are in the form of Binary Files i.e. .bin files. Here we are using Firmware Version 1.5.1, which stock ROM is of the type Non-OS SDK. Your application will need to use the ArduinoOTA library in order to support this. The library has built-in support for filesystem updates; your Arduino code doesn’t need to do anything special to support it. Open Esplorer, connect and press reset button on the ESP board.
