Is QBluetoothPermission() of PySide 6.6.* supported by latest Pyinstaller 6.4.0 on MacOs 13.0?

[Rida-Shamasneh]

I am trying to get rid of the following message which I get whenever I try to discover BLE devices:
Use of Bluetooth LE requires explicitly requested permissions.

I tried today to request bluetooth permissions expliclity but I am always getting "Denied!" !!

def __request_bluetooth_permissions_explicitly(self):
        ble = QBluetoothPermission()
        ble.setCommunicationModes(QBluetoothPermission.Access)
        status = QApplication.instance().checkPermission(ble)
        if status == Qt.PermissionStatus.Undetermined:
            print("Undetermined!")
            QApplication.instance().requestPermission(ble, self, self.__request)
            return
        elif status == Qt.PermissionStatus.Denied:
            print("Denied!")
        elif status == Qt.PermissionStatus.Granted:
            print("Granted!")

self.__discovery_agent.DiscoveryMethod = QBluetoothDeviceDiscoveryAgent.LowEnergyMethod
self.__discovery_agent.start()

• PySide6.6.2
• Pyinstaller 6.4.0 (the latest)
• info_plist file including "NSBluetoothAlwaysUsageDescription" string.
• MacOs 13.0

I wonder if Pyinstaller supports this?

So that we're all on the same page, a quick and dirty reproducer:

from PyQt6 import QtWidgets, QtCore

app = QtWidgets.QApplication([])
ble = QtCore.QBluetoothPermission()
ble.setCommunicationModes(QtCore.QBluetoothPermission.CommunicationMode.Access)

app.requestPermission(ble, print)

status = app.checkPermission(ble)
if status == QtCore.Qt.PermissionStatus.Undetermined:
    message = "Undetermined!"
elif status == QtCore.Qt.PermissionStatus.Denied:
    message = "Denied!"
elif status == QtCore.Qt.PermissionStatus.Granted:
    message = "Granted!"

window = QtWidgets.QLabel(message)
window.show()
app.exec()

If I put the following in the spec file:

app = BUNDLE(
    ...
    info_plist={
      "NSBluetoothAlwaysUsageDescription": "I want your bluetooth and I want it now",
   },
)

then I get a pop up that looks like:

and the Undetermined response but if I hit OK, then run again I get Granted.

Thanks @bwoodsend for the quick response.
Would it work with PySide6.6.2?

[Rida-Shamasneh]

I tested your logic with PyQt6.6.1 and worked as a charm.
It would be great if you can help with a PySide6 example.

[Rida-Shamasneh]

I tested the following PySide6 example that does the same as yours; But -unfortunately- it did not work:

from PySide6 import QtWidgets, QtCore
from PySide6.QtWidgets import QApplication

app = QtWidgets.QApplication([])
ble = QtCore.QBluetoothPermission()
ble.setCommunicationModes(QtCore.QBluetoothPermission.CommunicationMode.Access)


class Checker:
    @staticmethod
    def __func__():
        status = QApplication.instance().checkPermission(ble)
        message = ""
        if status == QtCore.Qt.PermissionStatus.Undetermined:
            message = "Undetermined!"
        elif status == QtCore.Qt.PermissionStatus.Denied:
            message = "Denied!"
        elif status == QtCore.Qt.PermissionStatus.Granted:
            message = "Granted!"
        return message


window = QtWidgets.QLabel(Checker.__func__())
window.setFixedSize(300, 300)
app.requestPermission(ble, window, Checker)
window.setText(Checker.__func__())
print(Checker.__func__())

window.show()
app.exec()

PS - I am not fully sure that my example code is 100% correct; because there is a slight change in the interface between pyqt6.6.1 and pyside6.6.*

@bwoodsend

It seems issue is in PySide6.6.* according to the following ticket I profiled to pyside devs:
https://bugreports.qt.io/browse/PYSIDE-2474

"We are aware of the issue and a fix is already in place. It should be available from 6.7. See https://bugreports.qt.io/browse/PYSIDE-2468, but you will have to use pyside6-deploy or Nuitka."

Looks like PySide6 is currently not including/linking plugins for requesting permissions on macOS, and that will be remedied by https://codereview.qt-project.org/c/pyside/pyside-setup/+/530714 (referenced in https://bugreports.qt.io/browse/PYSIDE-2468) in PySide6 v6.7 (and presumably v6.6.3, if that happens to be released before v6.7). So when new version of PySide6 is released, it should work if you add NSBluetoothAlwaysUsageDescription to Info.plist as in examples above.

@rokm
I downloaded and installed pyside6.7-dev version captured today 8-March-2024 and I was able to get a "Granted!" result.
However; when I built my tool with this dev version (with Pyinstaller 6.4.0); I noticed two issues:

• Some issues during BLE devices discovery procedure. I was able to tweak it a little bit, and I was able to discover my BLE device.
• But when I tried to connect; the tool crashed ( a SEG Fault) :(
  Anyway; These are different issues that probably have nothing to do with the reported issue here; and might have been occurred because I tried a dirty-dev build. Anyway; I do not think it would be part of v6.6.3 according to PySide dev comment shared in my comment above.

@rokm

PySide6.7.0 was released a couple of days ago. I tried to bundle my pyside6 via latest pyinstaller v6.5.0 .. but unfortunately seems not yet supported by QApplication.instance().requestPermission, am I right?

[Rida-Shamasneh]

I just noticed something strange:
The bundled app requests Bluetooth permissions successfully if the app does not exist in the list of apps under Privacy & Security / Bluetooth ,,, but if it is already there and disabled, then I can not request permissions ....

In other words; my question is:

• Shall this API be able to request BT permissions in all cases, especially if app is listed under Privacy & Security / Bluetooth but turned off there?
