The introduction of the Bluetooth 4.2 module has revolutionized the entire world. While there are other versions of Bluetooth out there too, it is extremely important to know the differences between the different versions of Bluetooth. That’s because it will help you have a better understanding of the 4.2 module technology. In this guide, SKYLAB will tell you everything you need to know about the Bluetooth 4.2 module and the differences between different modules out there.

What Is Bluetooth 4.2 Module?

Bluetooth 4.2 is the latest addition to Bluetooth technology. According to research, this upgrade will drastically improve the speed by 2.6 times. This means that the downloads will be super speedy as compared to the previous versions of Bluetooth.

In addition to this, you will get privacy upgrades as well. This means that systems like Apple cannot track you on their own unless you turn on the tracking system yourself. This is what makes this version our favorite already.

How Does Bluetooth 4.2 Module Work?

Now that you know the basics of the Bluetooth 4.2 module, let’s take a look at how does the technology actually works. To accomplish the task of data transfer, it uses a technology called FHSS. For those of you who do not know what FHSS is, it means Frequency-Hopping Spread Spectrum.

Piconets also play an important role in the working of Bluetooth technology. They are a network that you form with one master device and slave devices of up to seven. However, all these devices need to be within a radius of 10 meters. You should also remember that piconets operate in frequencies ranging between 2.4 and 2.485GHz.

Let’s take an example of a smartphone and a speaker with the Bluetooth 4.2 module technology here. The phone will first send out an inquiry to the speaker’s access point. This inquiry is an attempt to form a connection between the two devices. The connection establishes when both the devices synchronize their frequency and time together. While some devices ask to input a security code as well, others do not. So, entering a security code is not always a necessity.

There are antenna-equipped chips in both the smartphone and the speaker. These chips are capable of transmitting and receiving signals at a specific frequency. The smartphone sends these signals to the speaker so that it can understand them later. Additionally, there is an inbuilt software program as well. It reprograms the characteristic signals of the phone to the signals that the speaker can understand.
