Bluetooth is one of the most popular ways to transfer information today. This is due to many different factors, for example, one of them is that users can transfer absolutely any file.
Bluetooth wireless network
Bluetooth is a wireless network that allows users to transmit absolutely any information at a high speed. This data transmission technology is used in all modern mobile devices, laptops, some desktop computers (if an appropriate adapter is installed), printers, keyboards, etc. Technology such as Bluetooth works within a radius of 100 meters and allows various devices to communicate, interact with each other, and simply transmit various kinds of information. It is worth noting one significant nuance, which is that the range of this wireless network directly depends on various obstacles and interference on the way to another device.
Data transmission using Bluetooth technology involves the use of radio waves, with the help of which information is transmitted. Different devices can transmit information of some particular kind. For example, if two mobile devices try to transfer a file (music, video, application, or text file) to each other, then the transfer of the file itself will be carried out.
Other devices, for example, such as a keyboard or mouse, can also be connected to a computer or laptop via Bluetooth, that is, this technology not only provides for the transfer of specific files, but also allows devices to interact with each other.
Bluetooth profiles
Bluetooth has a number of different profiles, that is, functions and capabilities that are inherent in a particular device. For example, the Advanced Audio Distribution Profile allows a two-channel stereo audio stream - music - to be sent to a headset or other similar device. Audio / Video Remote Control Profile allows you to control the standard functions of most modern TVs, Hi-Fi equipment (DVD players, home theaters, etc.).
The Basic Imaging Profile, as the name suggests, allows you to transfer images to any Bluetooth-enabled device. Basic Printing Profile - a profile that sends text information, for example, to a printer or scanner. It should be noted that such a profile does not require any special drivers, which means that its use is many times better than HCRP. Cordless Telephony Profile - a profile that enables wireless telephony. There are a huge variety of such profiles, and each of them performs a specific function.
