FW to download on the EVAL "ESP32-C3-DevKitC-02" which uses "ESP32C3WROOM02" to use the AT commands

[Demetrio Magrin]

Hello,

I have to do a simple test to verify that the EVAL "ESP32-C3-DevKitC-02" using "ESP32C3WROOM02" communicates through the serial port UART1 and with AT commands.
What are the fundamental FW that I have to download with "flash_download_tool_3.9.4.exe" ?
Should I refer to "ESP32-WROOM-32_AT_Bin_V2.4.0.0.zip" or "ESP32-C3-MINI-1_AT_Bin_V2.4.2.0.zip" ?
With "ESP32-WROOM-32_AT_Bin_V2.4.0.0.zip" UART1 uses pins: GPIO16 (RX), GPIO17 (TX), GPIO15 (CTS), GPIO14 (RTS) which are all not available on comb connectors.
With "ESP32-C3-MINI-1_AT_Bin_V2.4.2.0.zip" the UART1 uses the pins: GPIO6 (RX), GPIO7 (TX), GPIO5 (CTS) and GPIO4 (RTS) which are all available on the comb connectors.

For the EVAL "ESP32-C3-DevKitC-02" which uses "ESP32C3WROOM02" which zip file should I refer to?
What are the main files to download to check the UART1 and AT commands?
What are the pins of UART1 ?

Can you help me ?
Thank you!
