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();
