Hi, we used ESP32-C3-WROOM-02 in our IoT application and have difficulty in locating the right firmware to run on it. We did try to download "ESP32-C3-MINI-1_AT_Bin_V2.3.0.0.zip" and can successfully loaded into the module. See attached capture of the flash download tool.
However, when we tried to communicate over UART (TX/RX/CTS/RTS) from STM32 CPU, we could not get any response from it. We also tried to modify the "factory_param.bin" to use only TX / RX without CTS / RTS pins and still not working. I'm wondering if there should be another AT binary specially made to work on ESP32-C3-WROOM-02...?

Hi, ESP32-C3-MINI-1_AT_Bin_V2.3.0.0.zip is available on ESP32-C3-WROOM-02, you can follow the documentation (https://docs.espressif.com/projects/esp ... inux-macos) on Linux or macOS to download the firmware, it should be able to run directly.
Re: Firmware for ESP32-C3-WROOM-02
After download the firmware with the flash_download_tool_3.9.2 tool, it will not restart automatically. For example, the firmware download to ESP32-C3-DevKitC-02 development board, you need to restart manually. After pressing the RST key, the command can be sent normally.
