Hi!
After working for several hours, we will get an BTHUSB ID5 (or other error) from the Bluetooth driver. Sometimes the Bluetooth can recover, other times it freezes and only a REBOOT of the PC will get the usb working again. Neither Devcon reset/disable, nor physically removing the dongle and inserting it back in allows the usb ports to work. furthermore, any USB device inserted after the error will not work until a reboot is performed.
I'm attaching windows logs, event viewer logs as well as a simple CS file where we scan for BLE advertisements, read services and characteristics, then disconnect. Run this example for a few hours with several peripherals and you will crash as well.
Were using inter NUCs, windows 10. latest BIOS and BLE drivers. This happens with different BLE dongles, with different chipsets, so I don't think the dongle is the cause.
We use Windows.Devices.Bluetooth under UWP and are having many issues related to the BLE drivers.

Here is a link to logs, event viewer errors and a simple C# program which if you run vs more than 1 peripheral, will produce the issue within a few hours.

Please advise.
Thanks!

    Hello,

    Welcome to Microsoft Q&A.

    Your issue that might be related to ble devicer and I'm afraid is not suitable to discuss in the Forum. It is not allowed for us to tell you about our the email or address and we also won't ask you for private information. For your scenario, I suggest that you might need to open a support ticket for this. Please contact our paid phone support at MS Support. You will get 1:1 support on that. Select Developer Tools -> Windows UWP Development -> Windows 10 Universal App Dev -> Devices and Sensors Development-> Bluetooth API in the support page and you could contact the team. Please kindly note that your support ticket will be free if it is Microsoft's issue.

    Thank you!
