Arduino Bluetooth Chat

A simple and minimal chat app which controls arduino via bluetooth.

At the moment the app is in beta, so there may be some bugs. Source code of the app https://github.com/lucazanrosso/BluetoothChat

The scheme of the Arduino project is in the images above. Code for Arduino/Genuino Mega for sending and receiving messages, tested on HC-05 and HC-06 bluetooth modules:
* * * * * * * * * *
void setup() {
Serial.begin(9600);
Serial1.begin(9600);
}

void loop() {
if (Serial1.available()) {
String s = Serial1.readString();
Serial.println(s);
}
if (Serial.available()) {
char c = Serial.read();
Serial1.write(c);
}
}
