What is Dual Mode Bluetooth

The dual-mode Bluetooth technology includes both Bluetooth Low Energy (BLE) and Bluetooth Classic. Devices that support both of these are compatible with dual-mode. Nowadays, this is the most advanced type of Bluetooth that comes in smartphones and smart devices.

Dual-Mode Bluetooth uses the features of both technologies to provide a more seamless user experience in supported devices. It is commonly used in wireless headphones/earphones, TWS, and speakers.

The Bluetooth Low Energy (BLE) is used to pair and control the devices with the phone, and Bluetooth Classic is used to stream the audio on devices. This enhances the user experience with faster pairing, media controls, and high-quality audio streaming.

What is Bluetooth Classic?

Bluetooth Classic or Bluetooth is a short-range wireless technology standard that uses radio waves to do a task wirelessly. It was introduced to remove the hassle of using cables. It transfers data from one device to another wirelessly and fastly.

Generally, people use the Bluetooth Classic on their phones, laptops, speakers, headphones, etc., for data sharing/transferring.

  • Exchange Data between Nearby Devices
  • Faster Data Transfers
  • Uses Radio Waves for Wireless Transfers

What is Bluetooth Low Energy (BLE)?

Dual Mode Bluetooth: Low Energy

Bluetooth Low Energy (BLE) is a part of Bluetooth, also known as Bluetooth Smart, released in 2011. It was introduced to offer the same features as Bluetooth Classic but with low power consumption.

As it uses low energy, the transfer speed is also very low compared to Bluetooth Classic. Therefore, it is not used to transfer large files, but it is suitable for small transfers with lower power consumption.

Many small AIoT products in the market, like sensors and tags, use BLE for connection. These devices can communicate with smartphones without having large batteries wirelessly.
