The IoT segment, and wearable devices as an important part of it, now urgently needs to unify protocols and standards for communications. Today there are 10+ solutions that claim to be good solutions for the Internet of Things space. But Bluetooth Low Energy (BLE) is the most likely to remain as the de-facto standard for data transfer for wearable devices that aim to be energy efficient.
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.
