I am making windows application that connects to nearby iPhones using BLE.
I'm using Windows App SDK to implement this feature.
What I want to do is, when I restart my application, I want to connect to previously connected device again.
I was thinking about saving the device's BLE MAC addresses when closing, but found out that BLE MAC addresses are often Random, and will change eventually.
I heard that BluetoothLEDevice.deviceId is constant as long as device is paired, but I couldn't find the reference.
What can I do to save previous BLE connections?

I found the uwp sample BluetoothLE. The sample saves the selected device's ID for use in other scenarios and then connects with the device's ID.
