Solved Qt 5.10 Windows & Bluetooth Assert-Error
-
Hello everyone,
I experimenting with Qt 5.10 and QtBluetooth lowenergy under Windows(10), now that it's finally supported. (MSVC2015 compiler and Qt-libs)
Using the LowEnergyScann-Example from Qt-Creator I run into an Assert failure in "qlowenergycontroller_winrt.cpp"
This happens in the "Scanning for Services" part of the example
This only happens with Windows, tried with IOS and MacOs and there I can scann the services fine.
Using a 3rd-Party BtLe-Scanner I can successfully scan my device for services(under windows) so it's not an hardware issue.I restarted my PC, in case any other program would access my Bt-Chip in my PC but the error is tenaciously remaining.
//The SourceCode responsible 490 void QLowEnergyControllerPrivateWinRT::obtainIncludedServices(QSharedPointer<QLowEnergyServicePrivate> servicePointer, 491 ComPtr<IGattDeviceService> service) 492 { 493 Q_Q(QLowEnergyController); 494 ComPtr<IGattDeviceService2> service2; 495 HRESULT hr = service.As(&service2); 496 Q_ASSERT_SUCCEEDED(hr); 497 ComPtr<IVectorView<GattDeviceService *>> includedServices; 498 hr = service2->GetAllIncludedServices(&includedServices); 499 Q_ASSERT_SUCCEEDED(hr); 500 501 uint count; 502 hr = includedServices->get_Size(&count); 503 Q_ASSERT_SUCCEEDED(hr); 504 for (uint i = 0; i < count; ++i) { 505 ComPtr<IGattDeviceService> includedService; 506 hr = includedServices->GetAt(i, &includedService); 507 Q_ASSERT_SUCCEEDED(hr); 508 GUID guuid; 509 hr = includedService->get_Uuid(&guuid); 510 Q_ASSERT_SUCCEEDED(hr); 511 const QBluetoothUuid includedUuid(guuid); 512 QSharedPointer<QLowEnergyServicePrivate> includedPointer; 513 if (serviceList.contains(includedUuid)) { 514 includedPointer = serviceList.value(includedUuid); 515 } else { 516 QLowEnergyServicePrivate *priv = new QLowEnergyServicePrivate(); 517 priv->uuid = includedUuid; 518 priv->setController(this); 519 520 includedPointer = QSharedPointer<QLowEnergyServicePrivate>(priv); 521 serviceList.insert(includedUuid, includedPointer); 522 } 523 includedPointer->type |= QLowEnergyService::IncludedService; 524 servicePointer->includedServices.append(includedUuid); 525 526 obtainIncludedServices(includedPointer, includedService); 527 528 emit q->serviceDiscovered(includedUuid); 529 } 530 }
Has anyone an idea what I could do to fix this or can confirm this error?
Meanwhile I guess I'll open an other bugreport x), they should know me by now.

actually turnes out, rebooting is no longer the rebooting it once was. After forcefully shutting down my Laptop(holding the power button untill you can hear the HDD-arm jumping into the off-State) the problem solved itself.
Windows is aggravating more and more with each day & update.

Hi
its controlled with
Power Options program. ( typing “power” in start)
Shutdown settings:
Turn on fast startupfor a one timer,
shutdown /s /t 0
also seems to totally power off.My main complain with win 10 is that is so ugly. the so called modern
look reminds me of windows for workaround. before we had true color or
design skills :) -
@mrjj thank you!
Very hitten "feature" -_-
Sometimes its very difficult to comprehend corporate decisions.

well they rewrote all of windows to make it compile on arm. they then used
1 billion dollars to marked a hopeless winrt table. It failed since ipads are just better at being a tablet. :)Since tables can wake up very fast, they added that to windows and its on pr default.
While sometimes annoying with development. its super nice when you use it as media center.
It can be off completely and be ready in a split second. and it plays anything.So the tablet story is not all for nothing. but close :)
