The ESL System electronically displays customer content (i.e. price, product, and promotion information) on the S- Labels, which have traditionally been printed or written on paper in places such as retail markets and warehouses. NEWTON S-Label wirelessly receives data from the S-Gate and updates the display with the new information provided. NEWTON S-Label is based on Bluetooth Low Energy (BLE) for low power wireless communication applications. It consists of an RF transceiver, RF circuitry and the ARM Cortex M3 MCU offering BLE based network protocol, MAC protocol and other peripheral devices. Figure 1.
