What is BLE? BLE stands for Bluetooth Low Energy, which was introduced as part of Bluetooth 4.0 Standard. It is aimed at helping low-power-consuming IoT (Internet of Things) and M2M applications within a short range. This was critical in realizing many modern IoT devices which are battery-powered. Like Classical Bluetooth technology, BLE works in 2.4 GHz ISM (Industrial, Scientific, and Medical) bands while inheriting some features from its predecessor with more focus on low power consumption. The maximum power consumption of a BLE application would be around 0.01 Watts to 0.5 Watts, with the same speed as that of classical Bluetooth. Difference Between BLE and Classic Bluetooth The main difference between Classic Bluetooth and BLE is in the consumed power. However, there are other major differences due to the architectural differences in each case. The use of 24-bit addresses as compared to 3-bit addressing in Classic Bluetooth allows BLE to

What is Bluetooth? Bluetooth is a famous low-power wireless technology choice. It is designed for use as Wireless Personal Area Network (WPAN) technology alongside technologies such as Wi-Fi and ZigBee. Applications of Bluetooth vary from mobile phone-based applications to vehicular sensor-based applications. However, unlike its counterparts, Bluetooth is specifically designed for shorter distances. Bluetooth was first introduced in 1994 by Ericsson. The sole purpose of introducing Bluetooth was to replace the use of wire cords and cables. In collaboration with Nokia and Intel, Ericsson formed the Special Interest Group (SIG) in 1996, which is the governing body for releasing and defining Bluetooth specifications. Over the years the alliance of SIG increased, thus leading to the development of Bluetooth technology. It is based on the 2.4 GHz ISM (Industrial, Scientific, and Medical Applications) frequency band. The initial versions of Bluetooth supported a bit rate of up to 1 Mbps. Bluetooth is also
