i want to transfer data from an rpi3 to a microcontroller (arduino or esp32) via the cable usb, let’s say that rpi3 was offline so there’s no mqtt or http
after searching i found that the solution are an arduino with shield usb host or an ESP32 S3
is there any way without this shield usb host?
I don’t think you need a shield or any additional hardware. Just write code to send data over the UART serial interface on an Arduino or ESP32 board, and connect it to the USB Type-A receptacle on the RPi3. Then, write a Python script on the Raspberry Pi to read from the serial port at `/dev/ttyUSB0`.
