Read serial data from an external device using USB port

Postby khayamgondal » Mon Dec 18, 2023 2:16 am

I have a 3D printer that exposes serial via a USB-C port to send & receive data. Can I connect it to an ESP32 and read the printer's messages? The goal is to run a small program on ESP32 that communicates with the printer via serial / USB and publishes it via MTTQ or HTTP.

I believe you want the esp32 to be a host. Correct?
