      Description

      I am using example project lowenergyscanner of QT. I want to rescan device after each 10s. So I added below line to at the end of function Device::deviceScanFinished()

      QTimer::singleShot(10000, this, &Device::startDeviceDiscovery);

      I connect my LE headset to Windows OS

      After that I run lowenergyscanner, after about 45 minutes then CPU usage up to 100%.

      I see CPU used by Device Association Service increases gradually
