It is better to keep baud rate below 115200. - Because Arduino library created a default instance HardwareSerial Serial(0), so you can use created Serial object directly (in example below) without create an instance by yourself. Send Serial Data to Host Using Arduino Hardware: In this model, the Arduino hardware sends data to your computer over the serial port 0 (USB port) of the Arduino hardware. 3V TTL Level. In another Arduino Library, there is reference to Serial2 #define mySerial Serial2 but in the esp32 code, there is no reference to such serial. Note: we already have similar question here, but the solution was to use package from umake, not fix for the Snap.
