About The Bluetooth And How To Use It




Most people have heard of Bluetooth, but many are unaware of what it is, how it works, and what they can do with it. Let us try to fill in the gaps with our complete guide, which includes common uses for Bluetooth and explanations of how to set it up.



What is a Bluetooth?
Bluetooth is wireless communication standard which allows electronic devices to connect and interact with each other. It can be found in a number of gadgets, from smartphones, to loudspeakers, to laptops and more.

Bluetooth doesn't rely on Wi-Fi, or mobile data or a cell network: as long as devices are Bluetooth compatible, and in close proximity to each other, they can take part in the wireless, two-way communication.

What do Bluetooth's version numbers mean?
Bluetooth has been through a number of major iterations since it was first introduced in 1999 and its first version (1.0) is difficult to find on any device now. The greatest difference between these versions is the speed at which they can transfer data, with the latest iteration, Bluetooth 4.2, being the fastest and most efficient of these.

Bluetooth 4.0 and above can be found on most modern Android smartphones.

How do I know if my phone has Bluetooth?
If you currently own an Android smartphone, it’s highly likely that it has Bluetooth. This is a low-cost, widely applicable and easy to implement component: unless your phone is extremely old or extremely cheap, it should have Bluetooth.
It's very hard to find an Android phone that doesn't have Bluetooth. 

What is the difference between Bluetooth and NFC?
Bluetooth and NFC are in many ways very similar: you can even use NFC in conjunction with Bluetooth for faster connections. The key differences are:

NFC doesn’t require "pairing" – which means linking two Bluetooth devices together – so it's quicker to begin data transfer
NFC operates over shorter distances (usually less than 10 cm)
NFC can be used for mobile payments, Bluetooth can't
Bluetooth 4.0, on the other hand, is said to have a range of at least 200 feet and it transfers data faster than NFC.
NFC and Bluetooth are both ways to wirelessly connect devices.

How do I use Bluetooth?
To use Bluetooth, you must first ensure it’s enabled on your device. Go to settings > Bluetooth and flick the switch to the on position.

Alternatively, pull down your notification shade by swiping downwards from the top of your phone and you will likely see the Bluetooth icon. Tap it to enable or disable it.

How do I pair my phone with a Bluetooth device?
Simple. Switch the Bluetooth device on, and then from your smartphone's Bluetooth menu (the path to which you can find above) look for the name of the device you wish to connect to and tap on it. (By default, the name of the device you want to connect to should be very clear.) A few moments later the devices should be paired.

Some Bluetooth devices require a PIN for the connection to be made: if you don't know what this is, consult the device manual.

What can I use Bluetooth for?
1. For listening to music

One of the most common uses for Bluetooth is to connect your smartphone to wireless speakers or headphones. The advantage of this for headphones is that you don’t need to worry about cables or wires becoming tangled or pulled; one of the reasons why Bluetooth is particularly useful for sports headphones.

2) Transferring files: the Bluetooth also acts as a good medium for transferring files between devices, though the only flaw is the transfer of large files like apps which may take a longer period of time and in some cases, it becomes unsuccessful. 

Their are many other uses of the Bluetooth which I may not have included, but if you have any in mind please include it in the comments box below thanks.
