R&Q:
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.
All things are interconnected in the intelligent era, and the Bluetooth low energy module has become the first choice for intelligent control applications of the Internet of Things. It is widely used in smart homes, consumer electronics, smart medical care, automobiles, smart wearable devices, smart buildings, and so on. With so many wireless modules that can transmit data, why is the Bluetooth low energy module selected for intelligent control of the Internet of Things? The main reasons are as follows:
1) Low power consumption-to solve the power demand
The low-power Bluetooth module has lower power consumption than the classic Bluetooth module and lower than the dual-mode Bluetooth module; only a button battery can work for 1-2 years or more. Compared with other wireless technologies and classic Bluetooth power consumption, it solves the problem. Power supply and endurance requirements of smart products.
2) Fast connection speed-no need to wait
The Bluetooth low energy module technology uses a very fast connection method and the connection time interval can be changed from a few milliseconds to a few seconds according to the actual application. It can be connected to the docking Bluetooth device instantaneously without waiting.
3) Large connection distance-not easy to disconnect
The connection distance of Bluetooth low energy module 4.0-4.2 is between 30-100m, and the connection distance of Bluetooth low energy module 5.0 is longer, up to about 300m (the specific application depends on the specific environment)
4) Good compatibility-don't worry about updating
The high version of the low energy Bluetooth module can be compatible with the low version, and the new version can be compatible with the old version
5) Low cost-reduce production costs
The cost of low energy Bluetooth module is lower than other wireless modules, which can meet the performance while greatly reducing the production cost.
