At WWDC 25, Dr. Swetank mentioned, “DeviceDiscoveryUI is for making connections between apps and from an app to another device. It supports pairing with both Apple and third-party devices.” I find the pairing process in DeviceDiscoveryUI via Wi-Fi Aware intriguing. I have two questions: Can we pair devices via Bluetooth first and then establish a Wi-Fi Aware connection? If I use DeviceDiscoveryUI, how should I write an Android program to correspond with it and achieve iPhone-Android pairing? The app is an official Apple app: https://developer.apple.com/documentation/wifiaware/building-peer-to-peer-apps.

The app is an official Apple app: https://developer.apple.com/documentation/wifiaware/building-peer-to-peer-apps. I have two phones, an iPhone 12 and an iPhone 13, both with Bluetooth turned on and connected to the same WiFi. The devices paired successfully the first time, but after I reset the Wi-Fi identifier in Settings - Privacy & Security - Paired Devices, the devices could no longer pair. Specifically, one device displays a PIN input pop-up, but the other device does not show the PIN. What could be the reason for this?

Apple's Wi-Fi Aware demo shows that pairing is required before establishing a connection. Is this pairing mandatory? Can Android devices pair with Apple devices? My Android device strictly supports Wi-Fi Aware 4.0 and I want to achieve interoperability with Apple devices.
