System Structure

The RTL8763E Bluetooth transceiver is a solution that integrates both Bluetooth transmitter and receiver functionalities. It allows bidirectional communication between Bluetooth-enabled devices by wirelessly transmitting and receiving data. The solution utilizes two RTL8763E chips, one for transmitting and one for receiving, and communicates through the SPI interface to establish and maintain Bluetooth connections. Additionally, it can also be used with a main processor over the UART interface, making it versatile for various applications like wireless audio streaming, data transfer between devices, and remote control capabilities.

The RTL8763E Bluetooth receiver solution is capable of receiving wireless audio or other data from Bluetooth-enabled devices. It can be connected to non-Bluetooth audio output devices, such as car stereos, home theater systems, or headphones. The receiver then converts the received digital signal into analog audio that can be played through the connected output device. It can also be connected to audio processors through interfaces such as I2S/UART/SPI to expand audio signal formats and provide additional transmission interfaces.

The RTL8763E implements a Bluetooth transmitter, which is a device capable of wirelessly transmitting audio or other data to Bluetooth-enabled devices. It can be connected to non-Bluetooth audio sources, such as TVs, computers, or stereo systems, through various interfaces. Utilizing Bluetooth technology, it sends the audio signal to Bluetooth headphones, speakers, or other receiving devices.

Practical Application Case

Bluetooth Auracast™ Audio Transmitter

The RTL8763E functions as the main Auracast controller, connecting the audio source from the audio processor via the I2S or UART interface. In addition, the RTL8763E can independently receive analog signals from a line-in or a physical microphone. Its built-in Bluetooth module enables Auracast broadcast functionality, completing the transmitter.

Application Scenario

Auracast broadcast audio application in a fitness room

Audiovisual fitness classes

In a fitness class, the instructor can use Bluetooth Auracast to broadcast music or verbal cues to participants wearing auracast enabled bluetooth headset. This can help to create a more immersive and engaging workout experience.

Advantages of Solution

CPU resource

MCU memory and CPU computing power provides basic sensor data processing and handles the interaction with external devices.

Equipped with a transmitter and a receiver
