Smart BT Card

Smart I has developed App for Bluetooth Low Energy is a power-conserving variant of Bluetooth personal area network (PAN) technology, designed for use by Internet-connected machines and appliances. Also marketed as Bluetooth Smart, Bluetooth LE was introduced in the Bluetooth 4.0 specification as an alternative to Bluetooth Classic. Like its predecessor, Bluetooth LE uses frequency hopping wireless technology in the 2.4 GHz unlicensed radio band to interconnect nearby devices. Unlike its predecessor, Bluetooth LE maxes out at just 1 Mbps while consuming just 0.01 to 0.5 watts. That’s up to one-third of the speed of Bluetooth Classic, at no more than half the power.
