Hi In order to use the UART connector on S6 v1.2 (for adding an ESP8266-based module), wouldn't it be needed to enable serial port 2 in Marlin configuration (serial_port_2 1) - and what can the baudrate be set at ? 250000 ? Or does the baud rate only affect SERIAL_PORT config (which is-1 and thereby USB) ?
Regards Brian
Yes , you need to enable serial port 2 , that is serial_port_2 1,in board it shows UART1 in the center part of the board, i think you can find it and better to use 115200.
