What Are IoT Devices?

Also known as the Internet of Things, the IoT plays a major role in the smooth working of Bluetooth technology. That’s why it is extremely important for you to know what IoT Devices are and how do they work.

So, for those of you who do not know, the IoT means the growing network of physical devices that need an IP address for the connectivity of the internet. Apart from this, it also includes the string of communication that allows you to connect to the IoT Devices.

These devices include a range of devices such as smartphones, security systems, tablets, and electronic appliances. You will be surprised to know that you can even include cars in these devices! So, it is basically any device that can connect to the internet.

Currently, more than 12 billion devices can connect to the internet and Bluetooth which is a big deal. Not only this, but the experts predicted that this number will increase by 26% in the year 2022 which is certainly a big deal!

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.
