"message" cannot be used as a function

Projects Programming
1

Hello,

I have a problem that I think is simple to solve but i'm a beginner so i can't understand it. When I verify my program arduino says (you can see it below) : "message cannot be used as a function"
Its a programm linked to an application that "should" change the delay on a waterpump if you press one of the 3 buttons (a, b and c).

Thanks for your help

#include <SoftwareSerial.h>
SoftwareSerial bluetooth(11, 10); // (RX, TX)

int led = 13;

void setup()
{
// Démarrer la liaison Bluetooth
Serial.begin(9600);
// Démarrer la liaison Série
bluetooth.begin(9600);
// LED
pinMode(led, OUTPUT);
}

void loop()
{
if (bluetooth.available()) {
int message = bluetooth.read();

if ( message != -1)
{
Serial.print( message());

// Si le message = A, allumer la LED
if ( message == 'a') {
digitalWrite(13, LOW);
delay (25000);
digitalWrite(13,HIGH);
delay (86375000);
}

// Si le message = B, éteindre la LED
if ( message == 'b') {
digitalWrite(13, LOW);
delay (25000);
digitalWrite(13,HIGH);
delay (43175000);
digitalWrite(13, LOW);
delay (25000);
digitalWrite(13,HIGH);
delay (43175000);
}

// Si le message = C, éteindre la LED
if ( message == 'c') {
digitalWrite(13, LOW);
delay (25000);
digitalWrite(13,HIGH);
delay (28775000);
digitalWrite(13, LOW);
delay (25000);
digitalWrite(13,HIGH);
delay (28775000);
digitalWrite(13, LOW);
delay (25000);
digitalWrite(13,HIGH);
delay (28775000);
}

}

}

      Serial.print( message());

What are those brackets doing after message ?

`` That was the problem, I feel so retarded that I haven't seen it :(((( thank you very much <3

you declare message as in integer, then print message with characters"

void loop()
{
  if (bluetooth.available()) {
   int message = bluetooth.read();
    
    if ( message != -1)
    {
      Serial.print( message());


      // Si le message = A, allumer la LED
      if ( message == 'a') {
        digitalWrite(13, LOW);
        delay (25000);
        digitalWrite(13,HIGH);
        delay (86375000);
      }

seems to me that should be a char
