Set baud rate for native USB serial CDC (usb_serial_jtag)

Postby theodm » Thu Aug 10, 2023 10:47 am

Hello,

I am using usb_serial_jtag to R/W data between PC and ESP32-S3.

It works correctly using default 115200 baud rate, but i know ESP32-S3 is USB 1.1 compatible and I saw ESP32-S2 was able to get 500KB/s on native USB using Arduino IDE: https://www.youtube.com/watch?v=-O-Bvscjx14

I searched a way to edit that default baud rate in exemples/source code but i couldn't find as well as menu config.

Is there a way to increase default baud rate of native USB CDC on ESP32-S3 ?

Thanks

No, the USB-serial-JTAG ignores any and all baud rate settings and simply sends/receives data at the maximum speed USB allows. What speeds are you getting?
