Since its inception, Bluetooth was aimed at mobile devices, although today it is possible to use the platform through different types of equipment such as smart TVs (Smart TV), smart wristwatches, media players and other electronic devices such as PCs or laptops that have a Bluetooth connection

What is Bluetooth and what is it for? How does it work and its use on mobile devices?

Bluetooth was born as a result of intense research by its co-creator, the Ericcson company. The same thing consisted in developing a type of platform that would allow its users to connect your devices via a wireless connection.



Thus was born, Bluetooth. Taking into account that this tool consists of intercommunications between wireless networks of various devices. It was developed by the American company Bluetooth Special Interest Group.

The main focus since its inception has been to limit the use of USB cable connections and make the data exchange process much easier. Likewise, connect your devices without expending a significant amount of power.

Subsequently, large tech companies such as Apple, Lenovo, Microsoft, Nokia, Toshiba and others joined. Who has contributed capital and human talent to the project development. The name comes from the Danish king Harald Blatand, and although it was a codename associated with one of the early versions of the search, I liked it so much that I formally adopted the Bluetooth name.

How does bluetooth work?

The platform allows to establish the connection between the devices through a system of geolocation not exceeding 10 meters in diameter. This means that both devices must be close to each other for the file exchange protocol to be effective.



How to establish a connection between Bluetooth devices to exchange information?

To exchange information it is necessary to perform some previous actions:

  • Each device equipped with Bluetooth services is associated with a code or a name to be identified. You have to activate the service from your device and activate the option "coupling".
  • Pairing or mating is the establishment of a connection between the two teams. When you activate the service, click on the option search to view available devices.
  • Once the device is selected, click on the option "Pair"  to establish a connection with it.
  • The other device will receive a notification to accept the request. By being connected you can exchange information.
  • After the pairing process is complete, the user can select the file type you want to share, click the option "Bluetooth" and then the information exchange process will begin.

Using bluetooth on mobile devices

Bluetooth was born in the mid-90s and its main goal was to be implemented in mobile devices of the time; which at the time were simple devices, with little storage space, which could only be used to send or receive messages and subsequent calls.

Currently, the service is available for high-end mobile devices, so it is important to know if your mobile is low-end, medium or high-end and the so-called Smartphones or smartphones. So basically what changed was the equipment and not the Bluetooth platform.


Today this platform has been very successful, being used approximately 7.000 times a day on mobile devices, in around the world, to send an application via Bluetooth from your mobile phone and share many files. This is because it is quite simple, practical and does not require internet or other payment services.


It is important to remember that Bluetooth is currently available for devices Intelligent as a soundbar with wireless connection, headphones, a Bluetooth keyboard that you can connect to tablets and countless other devices.

Although Bluetooth technology was developed more than 2 decades ago, it can be said that today it is quite useful for all users who require an exchange of information between their computers or devices, and although there are other means, none are so easy, safe. and practical.
