Pyside6 PYTHON chat example ?

Ravenboy

in the 'qt for python' docs there is a section on a Bluetooth qt chat example:

https://doc.qt.io/qtforpython-6.2/overviews/qtbluetooth-btchat-example.html#chat-client

some lines look like c++ and I am struggling to translate them into python:

like:
protocol << QVariant.fromValue(QBluetoothUuid(QBluetoothUuid.ProtocolUuid.Rfcomm))
<< QVariant.fromValue(quint8(rfcommServer.serverPort()))

I was thrilled when this page had a link at the bottom:
Example project @ code.qt.io
but au contraire - the example is not a python example, its in c++.

I'm hoping there is a Qside6 version of this somewhere.

I have searched the net (to no avail) for examples of using qside6 bluetooth classic to implement a bluetooth classic server

any ideas are appreciated.

Hi,

Not all examples have been completely ported to Python yet. Some of the code is auto-translated thus the issue you are seeing.

From a quick look, protocol is a sort of list and that line simply adds elements to it one by one.

Thanks,
and to further educate me, what is added to the list after the execution of
QVariant.fromValue(QBluetoothUuid(QBluetoothUuid.ProtocolUuid.Rfcomm)) .

QVariant.fromValue isn't defined in PyQT6

@Ravenboy
PyQt/PySide does not need QVariant because Python is happy dealing with everything as objects. Just ignore it, and hopefully any other mentions of QVariant. Here the code want to store a QBluetoothUuid and a small integer/byte in the list. You should be able to mix these happily in a Python list.

There are a few other basic types like this, e.g. QString is just handled with Python's inbuilt str type.

Thanks,
made progress, got thru the making of the chat server, and
serviceInfo.registerService(localAdapter.address()) returned True, finally

now onward, and pythonizing the rest of the low level stuff from the c++ chat demo
(don't need the user intercface objects, I am only using the bluetooth stuff until I decide its working.)

all of this is because at least on an apple silicon Mac, Python doesn't have bluetooth. (I'm using latest, 3.13)

thanks for the help - I've gotten far enough that I am discovering service just fine.
