==Application data transfer==
The protocol used for sending/receiving data over the network with UDS by official applications is [[PRUDP]](in some cases at least). In some cases at least this is with PRUDPS(additional encryption layer). This includes UDS-specific data in each frame, such as Mii data. Mario Kart 7 uses PRUDPS here.

==Data frames==
Data is transferred over the network using [[NWMUDS:PullPacket]]/[[NWMUDS:SendTo]]. That data is transferred using 802.11 data frames using CCMP encryption. The encrypted data contained in the frame starts with a 0xE-byte NWM header, followed by the actual application data from the previously mentioned commands. When [[NWMUDS:SendTo]] was used with dst_NodeID = broadcast, the data frame is sent to the 802.11 broadcast MAC address. Otherwise with a specific NodeID, the data frame is sent to the actual MAC address for that device.
