QMQTT

mqtt client for Qt

Please compile the library with Qt >= 5.3 version. On Windows you need to specify CONFIG += NO_UNIT_TESTS, since gtest is not supported.

Usage

#include "qmqtt.h"

QMQTT::Client *client = new QMQTT::Client(QHostAddress::LocalHost, 1883);
client->setClientId("clientId");
client->setUsername("user");
client->setPassword("password");
client->connectToHost();

Slots

void setHost(const QHostAddress& host);
void setPort(const quint16 port);
void setClientId(const QString& clientId);
void setUsername(const QString& username);
void setPassword(const QString& password);
void setKeepAlive(const int keepAlive);
void setCleanSession(const bool cleansess);
void setAutoReconnect(const bool value);
void setAutoReconnectInterval(const int autoReconnectInterval);
void setWillTopic(const QString& willTopic);
void setWillQos(const quint8 willQos);
void setWillRetain(const bool willRetain);
void setWillMessage(const QString& willMessage);

void connectToHost();
void disconnectFromHost();

quint16 subscribe(const QString& topic, const quint8 qos);
void unsubscribe(const QString& topic);

quint16 publish(const Message& message);
