Through Qt Maintenance Tool I can't find Mqtt module to install.
Unless something has changed, which apparently isn't the case here, you have to build
QMQTTyourself from source, as it's not available in Online Installer for open source users.See:

Thanks, with MinGW, I managed to connect Mqtt from manually assembled libraries. Can you please tell me how to solve the issue with the compilation Android app?

Please tell us first what issue it is...
Did you build mqtt for Android? -

@jsulm First I needed to do it for a window application, I did it, now I need to connect mqtt to a mobile application but there is aarch64-v8 architecture so compilation does not work.
@Sergey_85 said in Mqtt:

Just build it using Android NDK or your Android Kit in QtCreator.
And please, "does not work" does not tell anything. You should say what you tried and what happened.

@Sergey_85 And what happened? Does /home/ph/opt/Qt/6.8.0/gcc_64 contain Qt6Config.cmake or qt6-config.cmake like CMake requested in the error message?

@jsulm yes, the Qt6Config.cmake file is also in the folder
/home/ph/opt/Qt/6.8.1/android_arm64_v8a/lib/cmake/Qt6/Qt6Config.cmakeI haven't compiled from sources before, what's in the kit was enough for me, so I apologize if I'm asking something wrong or providing incomplete information, I'm confused(
