In-Depth Understanding of BLE Bluetooth Module Application Scenarios

BLE Bluetooth Module

The BLE Bluetooth module is a widely used wireless communication module, extensively applied in various smart devices, with main applications including: positioning tags, asset tracking, sports and fitness sensors, medical sensors, smartwatches, remote controls, toys, etc. Below is a brief introduction to some common applications of the BLE Bluetooth module.

Product Name Card

BLE Bluetooth Module: Refers to modules that support Bluetooth protocol 4.0 or higher, also known as BLE modules (Bluetooth Low Energy Module).

The biggest feature of the BLE module is the reduction in cost and power consumption, applied in products that require high real-time performance but have low data rates, such as remote control devices (mouse, keyboard), and data transmission from sensor devices (heart rate monitor, blood pressure meter, temperature sensor), etc.

Applications of BLE Bluetooth Module

1

Bluetooth Lighting Control Solution

The Bluetooth lighting control solution is primarily based on the SKYLAB BLE Bluetooth module SKB362, achieving functions such as color control of smart Bluetooth LED lights. SKYLAB will provide: 1) Product-level solutions (e.g., Bluetooth color control lights, air conditioning partners, etc.); 2) Hardware design support; 3) Software design support; 4) APP design (including iOS and Android, third-party cooperation); 5) Cloud platform support (third-party cooperation).

Bluetooth Lighting Control Solution

Bluetooth Lighting Control Solution Description: Pairing the mobile phone’s Bluetooth with the Bluetooth module on the color light to achieve APP command control of the color light’s Bluetooth, enabling different functions, such as adjusting preferred colors and brightness through a color palette or sound.

BLE Bluetooth Smart Lock Solution

Smart access locks are built on the existing access control system, adding a low-power Bluetooth transparent transmission module to achieve mobile phone Bluetooth protocol docking. Smartphones call Bluetooth services through an APP, send commands, and the smart access lock receives the Bluetooth command to control the lock’s opening and closing.

BLE Bluetooth Smart Lock Solution

Bluetooth Smart Lock Solution Description: The smart lock contains a BLE Bluetooth module SKB369, where the mobile phone reads the smart lock’s Bluetooth information through an APP, attempts to pair, and sends an unlock request to the server. The server sends an unlock command to the mobile phone, which receives the command and sends it to the smart lock via Bluetooth for unlocking.

Bluetooth MAC Address Scanning and Printing Solution

The SKYLAB Bluetooth MAC address scanning and printing solution includes a Bluetooth MAC address reading device, MAC address reading software, MAC address management software, QR code generation software, and QR code printing drivers, forming a complete solution.

Bluetooth MAC Address Scanning and Printing Solution

Bluetooth MAC Address Scanning and Printing Solution Description: Using a low-power Bluetooth module (such as SKYLAB’s BLE Bluetooth 4.2 module SKB360) as the host, scanning nearby devices, filtering based on broadcast names, selecting the device with the strongest surrounding signal, and obtaining the MAC address. After obtaining the MAC address, the data is sent to the label printer via serial port, which prints the required QR code.

The Bluetooth MAC address is printed in QR code form, facilitating the reading of the Bluetooth MAC address by Bluetooth products, effectively improving work efficiency.

Bluetooth Mesh Networking Solution

The Bluetooth Mesh network is a new network topology for establishing low-energy Bluetooth (Bluetooth Low Energy, also known as Bluetooth LE) communication between many devices (many: many). It allows the creation of large networks based on multiple devices, which can include dozens, hundreds, or even thousands of Bluetooth Mesh devices that can mutually transmit information. This application form undoubtedly provides an ideal choice for building automation, wireless sensor networks, asset tracking, and other solutions. With Bluetooth Mesh, many new application possibilities for smart homes have emerged.

Bluetooth Mesh Networking Solution

Bluetooth Mesh Networking Solution Description: The BLE Bluetooth module for Bluetooth Mesh networking—SKB369. With Bluetooth Mesh, only one control device is needed to simultaneously, easily, and efficiently control all functions within the smart home system. The powerful architecture of Bluetooth Mesh can also be expanded to meet the needs of offices, factories, industrial environments, and even cities, connecting millions of nodes without failure.

Bluetooth Beacon Indoor Positioning Solution

Beacon is a broadcasting protocol built on the basis of low-energy Bluetooth protocol, and it is also a low-energy Bluetooth slave device that possesses this protocol. Beacon devices are usually placed at fixed locations indoors, broadcasting a data packet to the surroundings at regular intervals. As an independent Bluetooth host during scanning, it will intermittently receive the data packets broadcasted by the Beacon, which can be used in supermarket promotions to push promotional information or coupons to customers who enter its vicinity, or through current received signal strength indicator (RSSI) and MAC address parsing to perform complex data calculations for indoor positioning of customers.

Bluetooth Beacon Indoor Positioning Solution

Bluetooth Beacon Indoor Positioning Solution Description: Indoor positioning combined with the Beacon technology, placing Beacon nodes in appropriate locations, along with rich APP applications, can conveniently provide users with indoor location services.
