I want to control animations on a esp32(S3) with WLED with another esp32-S3 over the serial Pins with UART. The problem is, that when I plug an USB-C cable in and sent commands they work fine, but WLED only watches the USB-C Serials, not the pins (RX/TX) on the esp itself. It seems that there is no way to change the serials not beeing the USB serials but GPIO 16/17 or GPIO 43/44. When the transmitter-esp sents commands, both esp even blink, but WLED just ignores them.
Did you try disabling the usb uart? i.e. compile with
-D ARDUINO_USB_CDC_ON_BOOT=0
Where can I do that?
You will need to replace Serial with Serial1 if you want to use both.
in WLED there is no way to change any serials, and I don’t want to use more serials, I just want the serials in WLED to be 17/18 or 43/44 or any GPIO on the esp controller, just not the USB-Serial
Some devices have two serial interfaces: CDC and “regular” serial/UART. If ARDUINO_USB_CDC_ON_BOOT=1 then Serial represents CDC port and Serial1 represents “regular” UART in such case.
You need to change source code for that to work.
