:-1: error: Unknown module(s) in QT: bluetooth; When trying to play around with the bluetooth functionallity of qt

[ViniDalvino]

I was trying to play around with QT bluetooth features however it gave me
:-1: error: Unknown module(s) in QT: bluetooth;
when trying to compile my code. I use windows 10 wiith msvc. Here is my code:

#include "mainwindow.h"
#include "ui_mainwindow.h"
#include <QtBluetooth/QBluetoothDeviceInfo>
#include <QtBluetooth/QBluetoothAddress>

MainWindow::MainWindow(QWidget *parent)
    : QMainWindow(parent)
    , ui(new Ui::MainWindow)
{
    ui->setupUi(this);
}

MainWindow::~MainWindow()
{
    delete ui;
}


void MainWindow::on_DispHeadphoneInfo_clicked()
{
    QBluetoothAddress headphoneAdrr("38:18:4C:02:F6:79");
//    QBluetoothDeviceInfo headphoneInfo(*headphoneAdrr, "Sony WH-Ch700N", )
}

Here is my qmake file:

QT       += core gui
QT       += bluetooth;

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

CONFIG += c++11

# You can make your code fail to compile if it uses deprecated APIs.
# In order to do so, uncomment the following line.
#DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000    # disables all the APIs deprecated before Qt 6.0.0

SOURCES += \
    main.cpp \
    mainwindow.cpp

HEADERS += \
    mainwindow.h

FORMS += \
    mainwindow.ui

# Default rules for deployment.
qnx: target.path = /tmp/$${TARGET}/bin
else: unix:!android: target.path = /opt/$${TARGET}/bin
!isEmpty(target.path): INSTALLS += target

@ViniDalvino You did not mention which Qt version you're using and how you installed it.

QT += bluetooth;

I Don't know how qmake handles semicolons, I would imagine not well, remove it

@J-Hilk Hey, I have a similar problem. Removing the ' ; ' isn't helping. Can you please suggest an alternative solution?

[Christian Ehrlicher]

@Aayushi Even for you it's relevant to answer the questions @jsulm asked. What Qt version, how id you install it, ...

[Aayushi]

@Christian-Ehrlicher Hey, I have installed QT 6.1.0. from this site: https://www.qt.io/download-qt-installer?hsCtaTracking=99d9dd4f-5681-48d2-b096-470725510d34|074ddad0-fdef-4e53-8aa8-5e8a876d6ab4 . The downloaded file was named: qt-unified-windows-x86-4.0.1-1-online.
Also, I am using Windows 10 with MinGW 64 bit compiler.

Hey, I have installed QT 6.1.0

Bluetooth is not yet supported in Qt 6. See https://www.qt.io/blog/add-on-support-in-qt-6.0-and-beyond

Install Qt 5.15.2 to use the Qt Bluetooth module.

@JKSH Thank you, I'll try installing it.
