Infineon Bluetooth Module, Low Cost, Low Power, Versatile Wireless Connectivity Solution

What is a Bluetooth module?
A Bluetooth module typically consists of a small circuit board including a microcontroller, radio frequency (RF) transceiver, and Bluetooth protocol stack for short-range wireless communication. A Bluetooth module typically connects to a host device, such as a microcontroller or computer, via a serial interface (e.g., UART, SPI, or I2C).


The Bluetooth module performs several functions, including:
Radio Frequency (RF) transmission and reception, where the module transmits RF signals to and receives signals from other Bluetooth devices;
Bluetooth protocol processing, where the module implements the Bluetooth protocol stack, including device discovery, pairing, and data transfer;
Data processing, where the module handles data transmitted between devices, including data encryption and decryption.

What are the types of Bluetooth modules?
According to technical standards, they are categorized into classic Bluetooth modules and low-power Bluetooth modules.
According to the function and application, it is divided into audio module, data transmission module and dual mode module.
According to power and transmission distance, they are divided into Bluetooth modules with transmission distance of 1 meter, 10 meters and 100 meters which are suitable for different scenarios.

Factors to consider when choosing a Bluetooth module include the required range, power consumption, and the type of host device it will be connected to.

What scenarios can Bluetooth modules be used in?

● Smart home devices: Bluetooth modules enable devices such as thermostats, lighting systems, and security cameras to realize the control of other devices with a smartphone.

● Wearable devices: Bluetooth modules are used in fitness trackers, smart watches and other wearable devices to enable communication and data transfer between smartphones and devices.

● Industrial automation: Bluetooth modules are used for industrial sensors, such as temperature and pressure sensors, to enable wireless connectivity and data transfer between devices.

● In-vehicle Bluetooth system: Connecting cell phones via Bluetooth to realize hands-free communication and enhance driving safety; music playback, transmitting music from cell phones to in-vehicle audio system via Bluetooth.
