AT commands not working

Hello,
I am trying to use to use AT commands but it doesn't show anything, not even an error.
I erased my esp32c3 using idf command but after using this command I started getting an invalid header error.
Then, I tried resetting the board to factory settings using flash download tools

I followed the guide given below for flashing the firmware to the esp32.
(https://docs.espressif.com/projects/esp ... guide.html).

I am successfully able to see the startup logs which means that the firmware is properly flashed.
But when I tried entering basic AT commands it did not respond, not even it showed any error.

Is there something I am missing or any further steps I need to do?

Note: I am using ESP32 C3 Mini-1

Hi,
Is your module ESP32C3? Maybe you should read the document of ESP32C3: https://docs.espressif.com/projects/esp ... ding-guide
