I conect my STM32 to the ESP32-C3-DevKit, and it works OK (with AT commands).
The STM32 connects its UART to pin GPIO6 and GPIO7 as it is explained in the AT-Project user Guide page 14
I don't conect the CTS and RTS.
I installed the ESP32-C3-Mini-1 on the PCB and connected the same line, it doesn't ...

I connect to TCP with AT+CIPSTART
And then I enter oassthrough mode with: AT+CIPMODE=1
I receive packets ok.
But
WhenI send a packet I get an error: ERROR (as if I am not in passthrough mode).
I tried sending: AT+SIPSEND (without = length) before the AT+CIPMODE and after it, and I still get the ...

Now I know that several of the question are answered in the AT-Commands examples in the
https://docs.espressif.com/projects/esp-at/en/release-v2.1.0.0_esp8266/AT_Command_Examples

So I revised the questions:

1. I understand that I can install only the: factory_MINI-1.bin
And this is instead of ...

I have few questions:
1. I understand that I can install only the: factory_MINI-1.bin
And this is instead of installing all the other binaries.
I am right?

2. After I installed the binarary, and I tested the AT+GMR command,
How do I send packets via the bluetooth (BLE) or via the WiFi?
Do you have ...

I want to use the ESP-AT project.
In their user manual, in Table 2: ESP32-C3 Series Hardware Connection Pinout
GPIO6 (RX)
GPIO7 (TX)
GPIO5 (CTS)
GPIO4 (RTS)
But, the pinout in the ESP32-C3 are:
GPIO20 (RX)
GPIO21 (TX)
So I don't understand what is right and why there is this difference.

I downloaded the ESP-AT project from Github and compiled it in Visual Studio Code.
I had several errors in the CMakeFiles.txt which I resolved with help of ChatGPT (I fixed the "string" commands).
But,
After all issues were resolved, it generated the following in the OUPUT tab:
AT-Commands/esp-at ...

I am using Visual Studio Code to compile the ESP-AT project.
I get a lot of errors in the MakeFiles.txt

For example in line 9:
string(TOLOWER $ENV{ESP_AT_MODULE_NAME} LOWER_NAME)
The error was that it didn't have the: OUTPUT_VARIABLE
string(TOLOWER $ENV{ESP_AT_MODULE_NAME} OUTPUT_VARIABLE LOWER ...

We also have the same probem.
If you solved it, can you post the code?

I have an ESP32-S3-WROOM module.
I downloaded the examples from GitHub.
I connected an HID device that sends data continuesly by a USB cable to the USB port in the module.
I run the "ble_hid_device" example, and I expect to receive data fro mthe device.

Hi,

I purchased ESP32-S3-WROOM from Freenove in order to ccreate a BLE bridge from my HID sensor to a PC.
I programmed the device to send data continuesly so I can see that the ESP can read the data from the sensor.
I used several HID exampes but in none of them I can see any data.

The example I ...
