# Bluetooth overview
The Bluetooth^®^ wireless technology is a short-range communications system that facilitates wireless exchange of data between devices. The key advantages of Bluetooth technology are as follows:
- Replaces the cables connecting portable and fixed electronic devices.
- Provides robust, power efficient, and cost-effective solutions.
- Facilitates flexibility of solutions and their applications.
The Bluetooth technology provides the following radio options.
| Radio | Description |
| --- | --- |
| Basic Rate/Enhanced Data Rate (BR/EDR) |
Offers optional EDR, alternate media access control (MAC), and physical layer (PHY) extensions.
Supports synchronous and asynchronous connections with a data rate of 721.2 Kbps for BR and 2.1 Mbps for EDR.
|
| Low Energy |
Enables products that require lower current consumption, lower complexity, and lower cost than BR/EDR.
Facilitates use cases and applications with lower data rates and has lower duty cycles.
|
BR/EDR and Low Energy radio options enable device discovery, connection establishment, and connection mechanisms. The optimal choice of radio depends on the use case or application of a solution.
The Qualcomm^®^ Linux^®^ supports Bluetooth solutions for the following kits.
