IoT Wireless Data Transmission Module: Bluetooth 5.0 VS Bluetooth 4.2

With the development of Bluetooth modules and various Bluetooth high-definition wireless transmission protocols in the past two years, the overall efficiency of Bluetooth wireless data transmission has been significantly improved. In the initial stage, Wi-Fi was preferred as the only wireless data transmission technology. Before the 5.0 standard was released, the old Bluetooth standard had certain inherent deficiencies such as poor transmission stability and large bandwidth restrictions.

Bluetooth is one of the wireless technologies that everyone is very familiar with and is widely used in the field of peripherals. In fact, there are different versions of Bluetooth. Currently, the common versions supported by Bluetooth are 3.0, 4.0, and 5.0. The higher the version of Bluetooth, the stronger the stability and the lower the power consumption, and the higher version of Bluetooth is backward compatible, so there is no need to worry about different connections failing due to the version.

In theory, the more advanced the Bluetooth chip, the higher the cost. So, what are the specific improvements of Bluetooth 5.0 compared to the previous Bluetooth 4.2 wireless communication protocol?

Bluetooth 5.0 is a Bluetooth technology standard proposed by the Bluetooth Technology Alliance in 2016. Bluetooth 5.0 has corresponding improvements and optimizations for the speed of low-power devices. Bluetooth 5.0 combines wifi to assist in positioning indoor locations, improving transmission speed, and increasing effective working distance.

Compared with Bluetooth 4.2, Bluetooth 5.0 has the following improvements:

1. Improved transmission rate: The maximum communication speed of Bluetooth 4.2 is 1Mbps, while the maximum communication speed of Bluetooth 5.0 is 2Mbps.

2. Improved transmission distance: The coverage range of the Bluetooth 5.0 standard is 4 times that of the Bluetooth 4.2, which is 300 meters. Серийный сервер

3. Improved information capacity in broadcast mode: The broadcast communication capacity of Bluetooth 5.0 has been upgraded from 31Byte of Bluetooth 4.2 to 255Byte.

4. Lower power consumption and compatible with older Bluetooth versions
