Hello
I want to build a remote control for my smartphone.
As Arduino I have a https://www.dfrobot.com/product-1259.html
Unfortunately the <ArduinoBLE.h> is not supported on this device.
I want to send only the numbers 1-4 to my MIT app.
Unfortunately I can only send to the Arduino but not receive on the app.
Unfortunately, no data arrives in the app.
I have also tried to change the data type.
Can someone give me a tip?

Arduino Code:
int inPin1 = 2;
int inPin2 = 3;
int inPin3 = 4;
int inPin4 = 5;
int button = 0;
void setup() {
Serial.begin(9600);
pinMode(inPin1, INPUT_PULLUP);
pinMode(inPin2, INPUT_PULLUP);
pinMode(inPin3, INPUT_PULLUP);
pinMode(inPin4, INPUT_PULLUP);
}
void loop() {
button = 0;
if (digitalRead(inPin1) == LOW) {
button = 2;
}
if (digitalRead(inPin2) == LOW) {
button = 1;
}
if (digitalRead(inPin3) == LOW) {
button = 4;
}
if (digitalRead(inPin4) == LOW) {
button = 3;
}
if (button > 0) {
Serial.println(button);
delay(1000);
}
}
