Is it possible to transfer files through ESP32C3 Mini with the existing AT Firmware V2.4?

Hi,

Maybe the AT+FS command (https://docs.espressif.com/projects/esp ... tml#cmd-fs) is what you want.

My goal is to send a .txt file from my phone to the ESP32C3Mini. Is there a way to do this? Can I use the existing AT Command Firmware V2.4?

I think it is possible, maybe you can try to establish a TCP connection with the mobile phone through AT, and then you can send data to the mobile phone in the transparent transmission mode.

Can I do this through BLE instead of TCP?

Maybe you can look at this example：https://docs.espressif.com/projects/esp ... s.html#id7

Yes, I have done this to transfer some data and it is working. What I would like to know is, If I have a text file or .hex file can I send it as a file instead of breaking it into line by line and sending?

How much data can I send through this process?

I think a lot of data can theoretically be sent, but in order to ensure that data is not lost, dual flow control needs to be turned on: AT+UART_CUR (https://docs.espressif.com/projects/esp ... d-in-flash)
