Bluetooth 5.0 module vs. Bluetooth 4.2 Module: Which One to Go For?

One of the versions of Bluetooth, the Bluetooth 5.0 module is the latest feature of wireless communication technology. This latest update has improved, range, speed, and compatibility as compared to its predecessor Bluetooth 4.2 module. However, some people are still reluctant to try it out.

So, if you are also one of those people, then this guide is for you. Here, SKYLAB will do a detailed comparison between the two modules. In the end, you will be able to decide for yourself which one is better for you.

What Is A Bluetooth Module?

Before we dive into details about the Bluetooth 5.0 module vs. the Bluetooth 4.2 module, let us first discuss a bit about the Bluetooth module. So, for those of you who do not know, it is a short-range wireless connection between mobile phones, computers, laptops, and other electronic devices. See, it’s as simple as that!

However, you should not confuse Bluetooth radio waves with the broadcast as there is a huge difference between the two technologies. What separates these two technologies from each other is that the Bluetooth waves do not travel much far away. Not only this, but the waves continuously switch frequencies as well.The majority of the Bluetooth devices come with a maximum connectivity range of 30 feet. However, the distance keeps on reducing with the presence of more obstacles such as walls, etc.

The devices that you connect through Bluetooth technology are extremely safe and secure. So, you will not have to worry about hacking. That’s because these devices operate on multiple different frequencies. As a result, the devices keep on hopping between multiple frequencies a hundred times per second. That’s why it is called “frequency hopping spread spectrum” as well.

There are several different versions or modules of Bluetooth. Each of these versions comes with improvements and changes of its own. The latest update in Bluetooth technology is Bluetooth 5.0 module.

What Do You Use Bluetooth For?

As we discussed above, we use Bluetooth technology to either pair mobile devices with other mobile phones or the fixed devices. These fixed devices can be anything such as your car, your earbuds, or your smart fridge. However, in some cases, they work in ways that are less apparent immediately such as a mouse or a printer to the computer.

Bluetooth and Wi-Fi technologies are often complementary. That’s because they not only work at the same time but offer the same connectivity as well. As a result, you might not understand at times which hardware is pairing with which device. All you need to remember is that if the devices were previously connected to the Bluetooth and they are still in range, they might try to connect to the Bluetooth again.

Since you often cannot realize whether the devices are connecting to one another via Bluetooth modules such as Bluetooth 5.0 module or Wi-Fi, it is a good idea to go to your device’s settings and open the Bluetooth tab. It will provide you with a list of all the devices that were previously connected or are already connected.

Another important thing to remember is that if you ever want to get rid of the Bluetooth device or do not plan to use it for a long time, you can simply remove it from your device by opting for “Forget this Device” from the Bluetooth’s setting. This will help you maintain control of the connection.
