Since it arrived in 2010 as part of the Bluetooth 4.0 specification, Bluetooth Low Energy (BLE) has become a topic of conversation among the public.
Bluetooth Low Energy (BLE) is an energy-saving version of classic Bluetooth technology, designed specifically for devices with low power requirements, such as wearable devices, sensors, and IoT (Internet of Things) devices.
Bluetooth Low Energy (BLE) allows devices to communicate with each other without consuming a lot of energy, making it very suitable for devices that require long battery life.

How Bluetooth Low Energy Works
Bluetooth Low Energy works on the principle of saving energy, especially at the data communication stage. Here’s how it works:
1. Fast connection (fast connection)
BLE can make connections faster, so the time spent on communication is shorter. This of course saves energy while increasing efficiency.
2. Standby mode (idle mode)
BLE uses an efficient standby mode. The device is only active when data is sent or received, thereby significantly reducing power consumption compared to classic Bluetooth.
3. Frequency and channel
BLE works on the 2.4 GHz frequency, just like classic Bluetooth. However, BLE divides these frequencies into 40 channels, allowing for more efficient communication with a much lower risk of interference.
4. Limited data transmission
BLE transfers small amounts of data that are still sufficient for applications such as fitness measurements, notifications, or location information.
Advantages of Bluetooth Low Energy
1. Wide reach
Even though it is energy efficient, BLE is still able to provide a wide range, which is around 100 meters under ideal conditions. This makes it suitable for smart home applications or location tracking.
2. Low cost
BLE uses simple components that are cheaper than other wireless technologies, making it an economical choice for IoT device development.
3. Low interference
With an organized channel system, BLE reduces the risk of interference with other devices working on the same frequency, such as WiFi.
4. Save energy
The main advantage of BLE is very low power consumption. Devices using BLE can last for years on a single small battery, making them ideal for sensors and wearable devices.
5. Compatibility with classic Bluetooth
BLE is often integrated with classic Bluetooth in modern devices. This means you don’t have to worry about the compatibility of old or new devices.
