ESP32 read data from computer USB

Postby joaopc23 » Tue Sep 22, 2020 12:48 am

Hello guys I'm thinking in buying an ESP32 board to use with arduino IDE, my projects needs are:
1. Bluetooth Communication
2. Receive packets and do a task at the same time (2 cores)
3. USB Serial read

ESP32 look the best board for my needs, but I've read that it does not support USB Serial reads, is that true? If so what can be done?

I was expecting to use WebUSB to send data to my board and it would read the bytes, does ESP32 can do that ?

ESP32 does not support a USB peripheral. It can certainly receive data from USB through a USB->UART adapter (typically included on a development board).
ESP32S2 does, but does not have bluetooth. Espressif even provides documentation on their products! https://www.espressif.com/en/products/socs/esp32-s2

Is there any board with built in bluetooth, 2 cores and USB to serial interface and battery support?

I found Hazzah32 arduino from adafruit, but it is more expensive than a normal ESP32 board.

What would you recommend ?
