Microsoft has determined that the OS will request a PIN from the wireless monitor one time and cache the PIN (in network devices and the registry). The PIN is verified before the P2P tunnel is established over the regular WIFI adapter. This setup is a clear Ethernet MICE connection.Ĥ) Miracast, CSE 200+ with PIN-enabled - WIFI connected (client mode) WIFI Direct, no ethernet connected. This protocol is called MICE, the traces are identical).ģ ) Miracast and CSE200+ with ethernet corporate network integration, internal WIFI not enabled, no PIN In this case, the WIFI is used only to detect an available wireless monitor, the PC will prefer the ethernet connection (if the BU is reachable via the Ethernet link. Use RTP as a filter in WiresharkĢ) Miracast and CSE200+ internal WIFI enabled, no PIN, plus ethernet connected Then the tunnel is established, and the session is open. In Wireshark use BootP and RTSP as the filters:Ĭ. If an available device capable of supporting Miracast is detected, then the PC runs a DHCP sequence in the tunnel to obtain an IP address from the BU.
The PC using Miracast runs a discovery service against the 192.168.137.0 network after optionally authenticating the device (more on this in the PIN section following) > BootP. The tunnel, initiated by the laptop, typically uses IP 192.168.137.1 as the anchor IP for the laptopī.
