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);

}

}
