• App sends two comma separated values ​​created by two Sliders.

70.3,60.4

• Arduino receives those values, separates them by comma, and adds them up.
  Using Serial.println(addition) returns the sum

130.70

String texto;
String a ;
String b;
float suma = 0.0;

void setup() { 
 Serial.begin(9600);
 Serial.setTimeout(200);
}

void loop() { 
  if(Serial.available()) {
    // texto = Serial.readString();
    // Serial.println(texto);
    a =  Serial.readStringUntil(',');
    b =  Serial.readStringUntil('\n');
    suma = a.toFloat() + b.toFloat();
   // Serial.println(a);
   // Serial.println(b);
    Serial.println(suma);
  }
}

• Clock1.TimerInterval = 100 and Serial.setTimeout (200) are important;
