# Stadiacast: reconstructing the Stadia Controller's Wi-Fi service

> Stadiacast recreates the network service used by the Stadia Controller's Wi-Fi firmware so the controller can connect to a local computer. The receiver answers boot and discovery requests, completes WebRTC and DTLS sessions, decodes input and sends rumble commands. Protocol notes record findings from firmware reading and live controller runs, with protobuf schemas and receiver code in the repository.
