What are the advantages of Bluetooth over low energy Bluetooth?




Bluetooth is a wireless technology that allows devices to communicate with each other over short distances. It is widely used for applications such as wireless headphones, speakers, keyboards, mice, smartwatches, fitness trackers, and more. However, not all Bluetooth devices are the same. There are different versions of Bluetooth that have different features and capabilities. One of the most recent and popular versions is Bluetooth Low Energy (BLE), also known as Bluetooth Smart. BLE is a subset of Bluetooth that is designed to be more energy-efficient and suitable for low-power devices. But what are the advantages of Bluetooth over low energy Bluetooth? And how do they differ in terms of power consumption, range, speed, and compatibility? In this article, we will answer these questions and help you understand the benefits of each technology.

Power consumption

The main advantage of BLE over Bluetooth is that it consumes much less power. This is because BLE uses a simpler and shorter protocol that requires less data transmission and processing. BLE also has a shorter connection time and a longer sleep time, which means that it spends less time in active mode and more time in idle mode. According to some estimates, BLE can consume up to 10 times less power than Bluetooth. This makes BLE ideal for devices that run on small batteries or need to operate for long periods without recharging.


The range of both Bluetooth and BLE depends on various factors, such as the device type, the environment, the interference, and the antenna design. However, in general, BLE has a slightly longer range than Bluetooth. This is because BLE uses a higher modulation index, which means that it can transmit signals with higher amplitude and clarity. BLE can achieve a range of up to 100 meters in ideal conditions, while Bluetooth can reach up to 10 meters. However, the actual range may vary depending on the real-world situation.


The speed of both Bluetooth and BLE also depends on various factors, such as the device type, the data type, the packet size, and the connection interval. However, in general, Bluetooth has a higher speed than BLE. This is because Bluetooth uses a higher data rate and a larger packet size than BLE. Bluetooth can achieve a speed of up to 3 Mbps, while BLE can reach up to 1 Mbps. However, the actual speed may vary depending on the data transfer requirements.


The compatibility of both Bluetooth and BLE depends on the device type and the software version. However, in general, Bluetooth has a wider compatibility than BLE. This is because Bluetooth has been around longer than BLE and has more devices that support it. Most smartphones, tablets, laptops, and other devices that have Bluetooth can work with any other Bluetooth device. However, not all devices that have Bluetooth can work with BLE devices. Only devices that have Bluetooth 4.0 or higher can support BLE. This means that some older devices may not be able to connect with BLE devices.


In conclusion, both Bluetooth and BLE have their own advantages and disadvantages. The choice between them depends on your needs and preferences. If you need a wireless technology that is more power-efficient and has a longer range, then you may prefer BLE. However, if you need a wireless technology that is faster and has a wider compatibility, then you may prefer Bluetooth.

Frequently Asked Questions

  • What is the difference between Bluetooth and low energy Bluetooth?
    Bluetooth and low energy Bluetooth are different versions of wireless technology that allow devices to communicate with each other over short distances. They differ in terms of power consumption, range, speed, and compatibility. BLE consumes much less power than Bluetooth but has a slightly longer range. Bluetooth is faster than BLE but has a wider compatibility.
  • How do I know if my device supports low energy Bluetooth?
    To know if your device supports low energy Bluetooth, you can check its specifications or settings. You can also look for the Bluetooth Smart logo or the BLE icon on your device or its packaging. If your device has Bluetooth 4.0 or higher, then it should support low energy Bluetooth.
  • Can I use low energy Bluetooth devices with regular Bluetooth devices?
    Yes, you can use low energy Bluetooth devices with regular Bluetooth devices, as long as they have Bluetooth 4.0 or higher. However, you may not be able to use all the features and functions of the low energy Bluetooth devices, as they may require a specific app or software to work properly.
