Cross-Platform P2P Wi-Fi: How the EU Killed AWDL
This post investigates how we got from Wi-Fi Direct to AWDL to Wi-Fi Aware, what makes Wi-Fi Aware technically superior, and why this shift unlocks true cross-platform peer-to-peer connectivity for developers.
In Instant mode, a device (say, an AR headset) triggered via BLE could immediately switch to a predetermined channel and begin a quick service discovery exchange with a peer, rather than strictly waiting on the periodic timetable. A subscriber device would perform complementary steps: calling session.subscribe(...) with the same service name and implementing onServiceDiscovered to detect the publisher, then possibly using subscribeSession.sendMessage(peer, ...) to send that “Hello.” At that point, either side could then use WifiAwareSession.createNetworkSpecifier() to set up an actual data path (network interface) for larger communication.
