Bluetooth API: Error "Could not await descriptor read result" happens when connecting to BLE service

NhungPham

I am trying to connect to my BLE device by function:

void Device::connectToService(QLowEnergyService *service)
{
 if (!service)
 return;
 if (service->state() == QLowEnergyService::DiscoveryRequired) {
 service->discoverDetails();
 }
}

It works well on Mac OS. But on Win 10 the error "Could not await descriptor read result" happens.

Please tell me know when this error happens. What can I do to fix it. Thank so much!

Below is the log.
