I bought a WROOM-02u module. Do I have to upload this AT _ Firmware to it ?
if yes then how and where I can download it ? the Espressife site is not letting me download it.

If you want the AT functionality, then yes. If your module specifically is an ESP-WROOM-02u, it contains an ESP8266 chip. See
here for the firmware you'd need for that.

You need some kind of firmware. If you want to use your ESP in AT mode with another processor, you need to use the AT firmware. If you want to use it standalone, you need some kind of SDK for your ESP8266.
