Hello,

 

I’m currently trying to use MQTT with Felgo, I’m not using the QT official libraries but it works without SSL.
The problem is the certificate file, I want to use SSL and I need to read a certificate. I can’t open the file like this :

p_sslConfig = QSslConfiguration::defaultConfiguration();

QFile certfile("./broker.emqxio-ca.crt");
Q_ASSERT(certfile.open(QIODevice::ReadOnly)); //! ERROR HERE
QSslCertificate cert(&certfile, QSsl::Pem);
p_sslConfig.setLocalCertificate(cert);

p_client = new QMQTT::Client(MQTT_URL, MQTT_PORT, p_sslConfig);

 

It seems logic that it’s not working, but how can I add a file to the APK and open it in C++ (Same problem for IOS).

I didn’t find help your documentation, did I miss it or is it even possible ?

 

I hope you’ll have a solution.

Thank you for your time.

Hi Florian,

 

the easiest solution is adding the needed files to the qrc resources files: https://doc.qt.io/qt-5/resources.html .

 

Once added your files are deployed together with your binary files and access through QFile is transparent on every platform.

 

Hoping that’s enough to get you started.
