> This is official firmware which turns the ESP into a "radio co-processor", so you can treat it like a SPI or UART Wi-Fi/BLE chip.
Kinda funny because the ESP8266 basically started off as a WiFi "co-processor" with AT commands sent over UART. People quickly discovered it had a good amount of power and you could run your entire application on the ESP8266 instead of using it as a co-processor. That led to an explosion in popularity for "makers" because the chip was so cheap and capable for projects at the time, and I think that led to the ESP32 becoming so widely known.
