config: sets data, parity, and stop bits. For lower baudrates use Software Serial speed: in bits per second (baud). If omitted, default 115200 bps is used (the only available on USB interface). Serial.begin(speed, config, rx, tx, *buffer, len) - returns error codeīaudrate baudrate to be used. Serial.begin(speed, config, rx, tx) - returns error code. The default is 8 data bits, no parity, one stop bit. For communicating with Serial Monitor, make sure to use one of the baud rates listed in the menu at the bottom right corner of its screen.Īn optional second argument configures the number of data, parity, and stop bits. Sets the data rate in bits per second (baud) for serial data transmission. For USB baudrate is fixed on 115200 bps, on UART it is possible to select baudrate. ![]()
