i know that I can use AT+CIPSEND to send data. I want to transfer the file in the SD card that is controlled by the MCU. The ESP32 is only the wifi module. And the PC is the webserver or FTP. I wants MCU searching the file to be send by itself. but it doesn't define the file name that will be transf...

I use arduino writing a LED example to the esp32.
and i just wants to use the AT command that is controlling by the STM32.
Is that made any effect? or might I erase the LED example?

我想问有机会从stm32控制esp32-wroom-32上传stm32控制的sd卡内的档案，经过wifi上传到虚拟伺服器吗？
目前看到的是stm32经过rxd0,txd0控制esp32.esp32已经写入最新factory_WROOM-32.bin.
如果可行有大概的流程或是需要引入的函数库吗？
目前网路上找不太到类似的流程。
