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
- Allows flexibility of solutions and their applications
The Bluetooth technology provides two radio options:
| Radio | Description |
| --- | --- |
| Basic Rate/Enhanced Data Rate (BR/EDR) |
- Provides optional EDR, alternate Media Access Control (MAC), and
Physical (PHY) layer extensions.
- Offers synchronous and asynchronous connections with a data rate
of 721.2 Kbps for BR and 2.1 Mbps for EDR.
|
| Low Energy (LE) |
- 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 LE 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 suite supports Bluetooth solutions for IoT platforms
of Qualcomm through the WCN6856 and WCN6750 connectivity chipsets. These highly
integrated chipsets comply with Bluetooth Core specification v5.0 and offer
Bluetooth® Low Energy long range support.
The following figure shows the various components of the Qualcomm connectivity chipset,
including the Bluetooth subsystem and its interaction with the application processor:

Note:
- The Qualcomm Linux platform allows you to develop applications for QCS6490
and QCS5430.
- The software support for the WCN6750 chipset will be provided in future
releases.
