Software Serial Console

You can communicate with ESP32 serial interface USB cable.

From ESP32 to PC

You can use the same code as in Hello World example:

esp32-examples/examples/Hello World/sketch/sketch.ino

Lines 1 to 8 in 19d93d1

	void setup() {
	Serial.begin(9600);
	}
	void loop() {
	Serial.println("Hello World!");
	delay(500);
	}

You can use Tools > Serial Monitor or any other serial client like Putty to read data from the serial port.

From PC TO ESP32

esp32-examples/examples/Internal Serial Console/sketch_pc_to_esp32/sketch_pc_to_esp32.ino

Lines 1 to 12 in ebb3c90

	void setup() {
	Serial.begin(9600);
	}
	void loop() {
	// Check if there is data comming
	if (Serial.available()) {
	// Read string until newline character
	String str = Serial.readStringUntil('\n');
	Serial.println("String: " + str);
	}
	}

You can use Arduino IDE Serial Monitor using Tools > Serial Monitor or any other serial client like Putty to send data to the serial port.
