but [Oscar] decided to take it one step further and program an Arduino over WiFi with the ESP8266. [Oscar] wrote a server script in Python that communicates with firmware running on the Arduino.

This flasher also connects the ESP8266 to a network and uploads firmware. It’s a stripped-down programmer without a serial terminal or the ability to toggle pins, but there are plans for making ...

It supports a wide range of microcontrollers, including the ATMega328, ATTiny series, ESP8266 ... the programming process is stable and reliable, which is crucial for successful firmware flashing.
