Ten common factors that affect the function of Bluetooth modules


At present, there are various types and sizes of Bluetooth modules to choose from on the market, but many application manufacturers still fall into a dilemma when purchasing Bluetooth modules. What kind of Bluetooth module is suitable? Which module is more cost-effective? What other factors should be considered when choosing a Bluetooth module? In fact, the most important factor to consider when purchasing a Bluetooth module is the type of product you produce and the application scenario of the product. Below, the Joinet Bluetooth module manufacturer summarizes some ten factors that affect the function of the Bluetooth module for your reference.

Ten Factors Affecting the Function of Bluetooth Module

1. Power consumption

Bluetooth is divided into traditional Bluetooth and Bluetooth Low Energy (BLE). Smart devices using traditional Bluetooth modules are disconnected frequently, requiring frequent repeated pairing, and the battery will be exhausted quickly. Smart devices using low-power Bluetooth modules Runs for a long time on a single button battery. Therefore, if it is a battery-powered wireless smart device, it is best to choose a Bluetooth 5.0/4.2/4.0 low-power Bluetooth module to ensure the battery life of the product. The low-power Bluetooth modules developed and produced by Joinet Bluetooth module manufacturers have the characteristics of low power consumption, anti-interference, small size, long distance, and low cost.

2. Chip

The chip determines the computing power of the Bluetooth module. A powerful "core" is the guarantee of the strength of the Bluetooth module. Internationally renowned BLE chip manufacturers include Nordic, Dialog, and TI.

3. Interface

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, and each interface can realize corresponding different functions. The corresponding Bluetooth module can be selected according to product requirements.

4. Transmission distance

Select the corresponding module according to the requirements of the product on the transmission distance, such as wireless earphones, wireless mice, etc., if the transmission distance is not high, you can choose the Bluetooth module with a short transmission distance, and for products that have certain requirements on the transmission distance, you must choose the corresponding module. Bluetooth module corresponding to the transmission distance.

5. Antenna

Different products have different requirements for antennas. At present, the commonly used antennas for Bluetooth modules include PCB antennas, ceramic antennas, and IPEX external antennas. If they are placed inside a metal shelter, generally choose a Bluetooth module with an IPEX external antenna.

6. Master-slave relationship

The master module can actively search and connect other Bluetooth modules with the same or lower Bluetooth version level as itself; the slave module is passively waiting for others to search and connect, and the Bluetooth version must be the same as itself or higher. The general smart devices on the market choose the slave module, while the master module is generally used on mobile phones and other devices that can be used as the control center.

7. Transmission rate

When selecting the Bluetooth module model, the required data transmission rate under the working state of the product should be taken as the reference standard, and the difference in the transmission rate determines the application scenario of the product.

8. Transfer content

The Bluetooth module can transmit data and voice information wirelessly, and is divided into a Bluetooth data module and a Bluetooth voice module according to functions. The Bluetooth data module is mainly used for data transmission, suitable for information and data transmission in public places with large traffic such as exhibitions, stations, hospitals, squares, etc.; the Bluetooth voice module can transmit voice information, and is suitable for communication between Bluetooth mobile phones and Bluetooth headsets. Voice message transmission.

9. Cost-effective

Price is a matter of great concern to manufacturers when choosing Bluetooth modules. As a national high-tech enterprise, Joinet has been deeply involved in the field of IoT modules for more than ten years, and can provide manufacturers with cost-effective low-power Bluetooth modules and solutions. It is not necessary to choose the best low-power Bluetooth module, but you must choose the most suitable and cost-effective one.

10. Package form

There are three types of Bluetooth modules: in-line type, surface mount type and serial port adapter. The in-line type has pin pins, which is convenient for pre-soldering and is suitable for small batch production; the surface mount module uses semicircular pads as pins, which is suitable for mass reflow soldering production for relatively small carriers; the serial Bluetooth adapter is used for When it is inconvenient to build Bluetooth into the device, it can be directly plugged into the nine-pin serial port of the device, and it can be used after power-on. Various types of modules should be reasonably selected according to the product structure.
