Bluetooth low energy (Bluetooth LE, BLE, marketed as Bluetooth Smart) is a wireless personal area network technology designed and marketed by the Bluetooth Special Interest Group aimed at novel applications in the healthcare, fitness, beacons, security, and home entertainment industries.
The Internet of Things (IoT) is gradually infiltrating our lives with the intention of making things easier by integrating many devices with our portable smart phones or PC. The bad news is that the user never knows for sure whether or not the device will work properly with other IoT devices.
The Bluetooth low energy is perfect technology for wearables because it is very energy efficient and inexpensive to boot. The BLE modules are tiny. The Bluetooth Special Interest Group Bluetooth SIG’s v4.2 and the new v5 specifications declare some excellent security requirements.
Bluetooth Low Energy has two important features: this technology has been developed for low energy consumption and a chip (or module) is much smaller than the classical Bluetooth chipset. BLE reduces device’s cost, size, and weight.
