Windows 10: Can't connect two similar BLE devices

I want to cennect two BLE controllers to one Windows PC.

First controller connects fine.

But trying to connect second - leads to error.

From System log I've fond error:

- System
- Provider
[ Name] BTHUSB
- EventID 35
[ Qualifiers] 49157
Level 2
Task 0
Keywords 0x80000000000000
In description it says, that my controllers use the same PERMISSION KEY if I translate correctly.

How can I connect my two controllers at thew same time?

Connecting to Bluetooth LE device GATT

I am trying to port an Android app to Windows 10 UWP (Anniversary Edition) for PC. The BluetoothLEAdvertisementWatcher API finds my device, but I am unable to enumerate the GATT Services for the device. This means I cannot connect to the device and read
data from the GATT.

In the Received callback of BluetoothLEAdvertisementWatcher I use the API BluetoothLEDevice.FromBluetoothAddressAsync. It always returns an empty GattServices list.

The following threads report similar behavior:

Why is BluetoothLEDevice.GattServices Empty

Apparently Win 10's BLE support assumes that a user will pair/bond a BLE device prior to using it. This is a showstopper in my project, because our BLE device does not support pairing/bonding.

This is disappointing from a Windows perspective, since the same scenario works fine on Android. I'd like to learn whether the Bluetooth LE APIs are on the Microsoft's roadmap to be improved soon.

Thanks.
