El Bluetooth It is a technology that remains revolutionary in these times, even though other types of connection protocols such as Wi-Fi have already appeared, which are also used to exchange files and data.
Over the years it has been updated to reach multiple versions, each time with better speed definitions and even with the number of devices connected at the same time, so let's learn a little about the types of Bluetooth what's in the market.

What is Bluetooth?
We can define Bluetooth as a technology or data transmission protocol, which uses a wireless network to exchange information. Its purpose is to eliminate cables for this type of task, but it is generally short-range and not within a visibility range like infrared.
On the other hand, Bluetooth devices are capable of sending and receiving (one at a time), any number of files, videos, music, data, voice and a host of other types of files, although at a speed considerably lower than that of Wi-Fi connections.
Using Bluetooth technology is another great opportunity. For example, connect a mobile phone to a speaker or headphones to play music. You can send files to the TV to mirror them on the screen, share internet, among other things.
The 2 Types of Bluetooth available on the market
There are two broad ways to classify the types of Bluetooth that devices already include today: class and its version. Both have some differences between them, so we explain everything you need to know about them below.
1. Bluetooth according to its range
There are values like frequency and scope transmission that must be calculated when including Bluetooth technology in a device. These vary depending on whether it operates indoors or outdoors.
But it is also analyzed amount of energy that the equipment must consume to select a speed and range, since in low energy conditions, the transmission can reach fewer places and the speed is considerably reduced.
The important thing is that the two devices can communicate at a relatively similar range, to avoid interruptions in service and data transmission, so There are up to four types of Bluetooth depending on their range.
It should be considered that depending on whether the device is in internal or external locations, the power will vary. In open spaces it can exceed up to 200m of range, while indoors it is reduced to a lower transmission and requires less energy.
1 Class
The power required for this class of Bluetooth is 100 mW, typically provided by computers and computers portable like laptops. Its indoor transmission range is up to 100 meters, but outdoors it expands to 200m.
2 Class
In contrast, Bluetooth class or type 2 requires a power of 2,5mW for proper operation. The range of these devices is reduced to 10m indoors and 50m outdoors. It is mostly used for adapters and computers.
3 Class
The values are reduced for third-class Bluetooth devices. The minimum range is 1m, but outdoors it is up to 10m maximum. Its use is more inclined towards phones, headphones and mobile devices that you can take with you.
4 Class
And the least powerful on the list is type 4. This type of Bluetooth is mostly used for specialized devices because it only has a range of 0.5 meters in total. The power required is 0.5 mW, so consume very little for what you need.
2. Bluetooth according to its version
This classification takes into account the changes and evolution that the Bluetooth protocol has had over the years. At each new stage, Some improvements are incorporated such as Smart technology, which may not work with lower version devices.
On the one hand, most devices on the market do not have the most recent versions of Bluetooth, because the adaptations of the equipment require an investment slightly superior in terms of infrastructure.
However, as new equipment continues to be developed on the market that requires the BT protocol to exchange data, new options will appear. Currently we have 12 types of Bluetooth depending on their version.
Bluetooth 1.0
Is first protocol which was released to the market and was the test version for its advancement. It is discontinued due to the number of problems and connectivity cuts.
Bluetooth 1.1
The update of the previous version was called BT 1.1. It added many changes and fixed bugs, and was commercially accepted. Up to 721 kbps could be transmitted between devices.
Bluetooth 1.2
It was the final stage of the first version, which appeared for fix the latest bugs present in the two previous versions.
Bluetooth 2.0
Thanks to the incorporation of technology Enhanced Data Rate (EDR), This version allowed data exchange to be increased to transmission speeds of over 2Mb per second, something revolutionary at the time.
Bluetooth 2.1
The change in this update was more of an introduction. Bluetooth 2.1 eliminated the annoying PINs for the security of transmissions, and now the devices could be added or paired with each other for direct exchanges.
Bluetooth 3.0
This time, the transmission rate is increased, calling it High Speed. It exceeded up to 24Mb/s.
Bluetooth 4.0
Bluetooth Low Energy (low power) was the feature added in this version, which retained the previous rate of 21Mb/s, but allowed the technology to be used in smaller, power-constrained devices.
Bluetooth 4.1
It allowed for the first time to use the Bluetooth protocol for transport data and the Internet and use shared connections.
Bluetooth 4.2
El IPv6 protocol It was developed for direct shared internet connections and was integrated into this update.
Bluetooth 5.0
It arrived in 2016 to add improvements in transmission rate, power and range, especially for internet exchange. 50Mb/s is the sending speed and reception, with a range of up to 240 meters outdoors.
Bluetooth 5.1
Here the improvements that were integrated were based on the location. With BT 5.1 it is You can know the precise location of connected devices in a measurement of centimeters.
Bluetooth 5.2 Audio
Designed primarily for audio devices. A proprietary codect called Low has been added. Complexity Communication Codec (LC3), which is capable of compressing the transmission of audio files, reducing energy consumption to the minimum possible.

Conclusions
Although he has a great rival, the Bluetooth protocol is far from disappearing. Its constant updates and improvements over the years demonstrate that its mission is to continue growing alongside technological devices, improving for meet those needs.
This is why we can currently use multiple types of Bluetooth to connect to various devices, exchange files, listen to music, control them remotely, among others. hundreds of other amazing uses.
