Online Multiplayer

This page is for the Switch equivalent of online/local protocol PRUDP.

Note: the wifi protocol used for local-WLAN is different from UDS, which 3DS and Wii U used (see here).

The Switch still uses UDP for peer to peer communication (packets starting with 0x32AB9864) - see here regarding Pia. For Nintendo server comms, WebSockets are used instead of UDP (more information).
