Bluetooth Low Energy for the Internet of Things

Bluetooth Low Energy was built to fulfill the requirements of the Internet of Things. Bluetooth SIG took a significant step when they decided to revamp the protocol stack of the Bluetooth. Bluetooth Classic was successfully transformed into Bluetooth Low Energy and adopted rapidly in the IoT devices and more importantly, in cellular phones. Bluetooth low energy can be summarized in two basic factors: power efficiency and simple architecture. While ZigBee is commercially successful and has been used for quite a while, Wi-Fi and Bluetooth Low Energy are the only famous and widely spread standards used in consumer electronics. If the judgment criteria are strictly on the basis of the adoption rate, Bluetooth Low Energy surpasses ZigBee as the adoption rate of the ZigBee is almost zero in the smartphones.
