How to send and receive QVariantMap with pyqt5 QDatastream ?

[RahibeMeryem]

Hi,

I can send QVariantMap from C++ to the python client and can receive with:

           VariantMap  = out.readQVariantMap()  ##map["dbname"]
            png         = VariantMap["PNG-image"]
            UserName    = VariantMap["mq_username"]
            np_database = VariantMap["np_database"]
            category    = VariantMap["category"]

How can I send the same QVariantMap from python ? I am using mtqq for messaging and utilizing the QDataStream.

Hi,

What are you using on the Python side for MQTT communication ?

Just send your data using the client. You'll get the message on the other side.

I coulnt find the QVariantMap in the PyQt5 to receive in c++ side

Likely because it's a dict.

In any case, why are you trying to send a QVariantMap since you are using a different library to communicate with your mqtt server ?
