Five application scenarios of BLE module

BLE module, as a PCBA board with integrated Bluetooth wireless technology function, mainly used for short-distance wireless communication, has been as the backbone of the development of wireless transmission of the Internet of Things. So what are the applications of BLE modules in real life?

1. BLE module applied to smart medical

Current health and medical devices are usually wearable products or other small items. Through the BLE module, the health data collected in real time by the sensors of the health medical device will be transmitted to the computer equipped with the BLE module. The MCU processor corrects the values of the collected data. The correct value can be transmitted to the file through the corresponding interface, and the patient's health data can be transmitted to the screen through the BLE module. It can also receive and analyze the received health data through the APP, which severs as a real-time monitoring of the data.

2. BLE module Mesh ad hoc network intelligent lighting

The BLE module builds a network and synchronizes with the cloud using a single control device, simplifying and efficiently controlling all functions in a smart home system. In the Bluetooth Mesh smart lighting solution, users can control any light or a group of lights in the Mesh network by connecting to any LED light in the Mesh network through a mobile phone, and grouping, dimming, and color adjustment, scene setting of the mesh network LED lights. The Bluetooth Mesh architecture can be extended to meet the needs of offices, factories, industrial environments and even cities. And millions of nodes can be connected without failure.

3. BLE module applied to smart wear

Since the low power consumption of Bluetooth Low Energy (BLE module) has been widely used in smart wearable terminals, many smart devices rely on Bluetooth technology for wireless connection and data exchange, the most common such as smart bracelets, smart necklaces, etc. Low-power technology can achieve the lowest power consumption for short-range communication, thus greatly extending the running time of wearable devices.

4. BLE module is applied to Bluetooth MAC address scanning and printing

• BLE module acts as the host in the Bluetooth MAC address scanning and printing solution
• Scan peripherals
• Filter by broadcast name
• Screen out the device with the strongest signal around
• Get MAC address
• After obtaining the MAC address, send the data to the label printer through the serial port
• The label printer prints out the QR code that meets the requirements

Printing the Bluetooth MAC address in the form of a two-dimensional code, which is convenient for Bluetooth products to read the Bluetooth MAC address and can effectively improve the efficiency.

5. BLE module applied to smart door lock

In the application scenario of smart door locks, the use of Bluetooth technology can meet the needs of different users and permissions, while ensuring confidentiality. Installing the BLE module inside the door lock, people can read the Bluetooth information of the smart lock in real time through the APP, then pair it, send an unlock request to the server, and the server sends the unlock command to the mobile phone. The BLE module sends the command to the smart lock door, and then unlocks it. Very convenient, fast and safe.
