Abstract.Nowadays there is a research on ambient living and smart building applications to make people life more confortable. This kind of applications, in general, requires the position where a person is in a building to act according it and to any physical parameters that are measured from the person, to determine, for instance, if the air condition has to be switched on or off, the room temperature has to be put up or down or the music has to be changed from classical to pop, or vice versa. This paper presents an indoor position solution based on BitCloud Stack, a full-featured, second generation embedded software stack from Atmel.
