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 two radio options:
| Radio | Description |
| --- | --- |
| Basic Rate/Enhanced Data Rate (BR/EDR) |
- Offers optional EDR, alternate media access control (MAC), and
physical (PHY) layer 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 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:
| Kit | [Hardware system-on-chip (SoC)](https://docs.qualcomm.com/bundle/publicresource/topics/80-70015-115/soc.html) | Bluetooth chipset | Bluetooth stack |
| --- | --- | --- | --- |
| Qualcomm RB3 Gen 2 Development Kit | | | BlueZ |
| Qualcomm IQ-9100 Beta Evaluation Kit | | | BlueZ |
[^1^](https://docs.qualcomm.com/doc/80-70015-13/topic/introduction.html#fnsrc_1) The software support for the WCN6856 chipset will
be provided in future releases.
