A profile is a collection of information about you, provided by you, in a particular category.
Each profile type in MiitWell is designed to encourage a valuable conversation. When you set up your profiles, you can choose from the many available types (with more coming in each update) then customize the profile to suit your particular needs.
Once that profile is available, you choose to broadcast it or not. Only profiles that are actively broadcasting can be seen by other devices in the room. As far as receivers (the other people who may see the information), each broadcasting profile alerts receivers to the broadcast then, as needed, supplies a summary or the profile details to the other device on request.
