What Is a Bluetooth® Chipset?

Bluetooth module is a PCBA board with integrated Bluetooth function for short-range wireless communication. It is divided into Bluetooth data module and Bluetooth voice module according to function. Bluetooth module refers to the basic circuit set of the chip with integrated Bluetooth function, which is used for wireless network communication. It can be roughly divided into three types: data transmission module, Bluetooth audio module, Bluetooth audio + data two-in-one module and so on. General modules have the properties of semi-finished products and are processed on the basis of chips to make subsequent applications easier.

The Bluetooth module refers to the basic circuit set of the chip that integrates the Bluetooth function and is used for wireless network communication. It can be roughly divided into three types: data transmission module, remote control module, and so on.
For end users, the image points: Bluetooth module is a semi-finished product,
As a short-range wireless communication technology that replaces data cables, Bluetooth supports point-to-point and point-to-multipoint communication, and wirelessly connects various data and voice devices in a home or office into a pico-net. Several Piconet can also further realize interconnection, forming a
The Bluetooth module is divided into 1.2, 2.0, 2.1, 4.0 and the latest 4.1, 5.0, and 5.1 according to the standard.
The Bluetooth module is divided into a data Bluetooth module and a voice Bluetooth module according to the purpose. The former completes wireless data transmission, and the latter completes wireless data transmission of voice and stereo audio.
The Bluetooth module is divided into flash version and ROM version according to the chip design. The former is generally a BGA package with an external flash, and the latter is usually a QFN package with an external EEPROM.
The Bluetooth module is divided into BroadCom Bluetooth module, Dell Bluetooth module, and CSR Bluetooth module according to the chip manufacturer;
The Bluetooth module is divided into a data Bluetooth module, a serial Bluetooth module, a voice Bluetooth module, and a car Bluetooth module according to the purpose;
The Bluetooth module is divided into CLASS1, CLASS2, CLASS3 according to power;
The Bluetooth module is divided into classic Bluetooth module (BT) and low-power Bluetooth module (BLE) according to the application and supporting protocol.
The Bluetooth module is divided into a single-mode Bluetooth module and a dual-mode Bluetooth module according to the protocol support;
The Bluetooth module is divided into a Bluetooth data module and a Bluetooth audio module according to the application;
Bluetooth modules are divided into industrial and commercial grades according to temperature;

The interface of the Bluetooth module is divided into serial interface, USB interface, digital IO port, analog IO port, SPI programming port and voice interface.
When only data transmission is needed, the system should use a serial interface (TTL level) as much as possible, so that modules on the market can support it. If an IO port is really needed, Bluetooth software development needs to be performed according to needs, time cost and economy. The cost is relatively high.
The Bluetooth module is generally composed of a chip, a PCB board, and peripheral devices.
Different Bluetooth modules have different external lead pins due to different functions and applications.
