You probably ask yourself what to eat for dinner after work. There are a number of mobile applications for recipes.
Each shelves broadcasts what items it displays so that the mobile can detect beacons around. The information from beacon includes its characteristics and RSSI (Received Signal Strength Indicator), the power present in a received radio signal. The value of RSSI indicates the distance between its beacon and the mobile.
The Le Basket sorts items for the selected recipe by proximity.
