  • 5.0/4.2/4.0 Bluetooth module contrast difference


Bluetooth has been improved step by step from 4.0-4.2-5.0, bringing more functions. Because the Bluetooth module uses different versions of Bluetooth chips, the functions are different. Createk develops and produces 4.2/5.0 low-power Bluetooth modules. The comparison and differences of 5.0/4.2/4.0 Bluetooth modules are listed below:


5.0 Bluetooth module relative to 4.2 Bluetooth module:


1) The transmission rate is increased by 2 times


Bluetooth 5.0 increases the current transmission speed by 2 times. The maximum communication speed of Bluetooth 4.2 is 1Mbps, and the maximum communication speed of Bluetooth 5.0 is 2Mbps.


2) The transmission distance has been increased by 4 times


The coverage of the Bluetooth 5 standard is 4 times that of Bluetooth 4.2. Improve the accuracy of indoor positioning.


3) The information capacity of the broadcast mode is increased by 8 times


Its broadcast communication capacity has been upgraded from 31Byte of Bluetooth 4.2 to 255Byte. The enhanced broadcasting capability will bring better beacons to create more location-based indoor positioning services and navigation services, and data transmission can be realized without pairing and connection. , The accuracy of indoor positioning is less than 1 meter,


4) Lower power consumption and compatible with older Bluetooth versions


In order to meet the needs of the mobile Internet of Things, its power consumption is lower and it is compatible with the old Bluetooth version.




4.2 The Bluetooth module is relative to the 4.0 Bluetooth module:


1) Faster data transmission


Compared with 4.0, under the Bluetooth 4.2 standard, the data transmission speed between devices is increased by about 2.5 times, and the amount of data that can be accommodated in a Bluetooth smart data packet is about 10 times that of the previous one.


2) Higher security


In addition, the security of Bluetooth 4.2 has also been improved. If the user's permission is not obtained, the Bluetooth signal will not be able to try to connect and track the user's device, and it will not be able to perform intelligent positioning.


3) More powerful functions


On the other hand, the new standard also promotes the introduction of the IPv6 protocol into the Bluetooth standard. Bluetooth 4.2 devices can directly access the Internet through IPv6 and 6LoWPAN, and support low-power IP connections.


  • Three advantages of BLE low energy Bluetooth module?


BLE Bluetooth module has lower power consumption and long power supply time

Bluetooth low energy is used in smart products, and it can work for a year or two or even longer with a small battery. Compared with other wireless technologies and the power consumption of classic Bluetooth, this is the communication technology that smart products are willing and desirable. .


Low energy Bluetooth module connection speed is fast

The Bluetooth low energy module technology uses a very fast connection method, and the connection time interval is variable. This interval can be set from a few milliseconds to a few seconds according to the specific application. It can be connected to the smart phone almost instantly, which greatly reduces the waiting time .


Low energy Bluetooth module uses unlicensed frequency band

Because Bluetooth low energy technology is a free electromagnetic frequency band, the 2.4GHz frequency band that Bluetooth low energy runs on is exactly an electromagnetic frequency band that is completely free. Others such as WiFi and induction cookers use the 2.4GHz frequency band. Because this frequency band does not need to pay special authorization fees to the radio management department.




  • In which areas can the Bluetooth low energy module be applied?


Createk currently has 3 Bluetooth modules, all of which are low-power Bluetooth modules, all of which use Nodic Bluetooth chips, which can be active and one-to-many.

Createk Bluetooth module can be used in different scenarios, used in smart homes, used as smart control, such as: LED Bluetooth module, light control Bluetooth module, smart lighting Bluetooth module, switch Bluetooth module, electronic scale Bluetooth module; can be used for safety control, as The key to open, such as: access control Bluetooth module, barrier Bluetooth module, smart lock Bluetooth module, elevator Bluetooth module; used for smart medical treatment, used for data transmission, such as: bracelet Bluetooth module, and other applications, such as: balance car Bluetooth Module, Bluetooth module for walkie-talkie
