Classic Bluetooth (BR/EDR):
Classic Bluetooth, also known as Bluetooth Basic Rate/Enhanced Data Rate (BR/EDR), is a wireless communication standard designed for short-range communication between devices. It operates in the 2.4 GHz frequency band and supports data rates ranging from 1 to 3 Mbps. Classic Bluetooth is commonly used for applications such as audio streaming, file transfer, and device connectivity. It is well-suited for scenarios where higher data transfer rates are required, but it tends to have higher power consumption compared to Bluetooth Low Energy.
Bluetooth Low Energy (BLE):
Bluetooth Low Energy (BLE), also known as Bluetooth Smart, is a wireless communication standard developed as a part of the Bluetooth 4.0 specification. BLE is optimized for low-power, short-range communication, making it suitable for applications in the Internet of Things (IoT) and other battery-operated devices. It operates in the same 2.4 GHz frequency band as Classic Bluetooth but achieves lower data rates, with a maximum of around 1 Mbps. BLE excels in scenarios where power efficiency is a priority, and devices need to operate for extended periods on small, coin-cell batteries.
