Bluetooth Windows XP, 7, 8.1, 10, 11, Android, iOS

In this rating, we will evaluate on a 10-point scale the best of the unusual, interesting and even strange Bluetooth gadgets (sometimes there will be several) that no one would decide to google on their own. Many people have been successfully using wireless mice, keyboards, joysticks, headsets, microphones, speakers, and Bluetooth headphones for a long time. There is no such thing in this rating. A wireless Bluetooth module can be found in the most unusual devices.

Almost all modern mobile devices, in particular Android smartphones and tablets, are equipped with a built-in Bluetooth application for Android. Below in this material we will also focus on the main functions for making the most effective use of the built-in Bluetooth application for Android. With its help, the user can receive and send any files, for example, photos or videos, control various devices, including a smart TV or home stereo system, directly broadcast audio to compatible headphones and speakers, and much more.

In 1994, Ericsson (since October 2001 Sony Mobile Communications Inc.) began developing a wireless alternative to the wired RS-232 standard. In 1998, at the initiative of Ericsson, the Special Interest Group (SIG) was founded, which at that time included four more giants of the telecommunications industry: Intel, IBM, Toshiba, Nokia. Also in 1998, a unique Bluetooth brand and logo was developed for a new energy-efficient and cheap wireless data and sound transmission technology.

The market niche of Bluetooth is short-range radio communication, which is cheap in terms of embedding in various devices and efficient in terms of power consumption. Data transmission in energy-efficient modes requires a minimum of energy - about 10 mA, as well as only 0.3 mA in standby mode. On demand, the sleeping device instantly gets in touch, sends or receives a packet of information in a fraction of a second, and again goes into standby mode with minimal power consumption.

A Bluetooth connection is the transfer of data and/or sound between two or more devices. Pairing between compatible devices is required to establish a wireless connection. Pairing is necessary to organize communication between devices. Before Bluetooth connection, you need to register the pairing information for each device. The initialization or procedure for establishing a Bluetooth connection between several devices is divided into three stages: secret key generation, link key generation, authentication.

To organize a connection via Bluetooth, you first need to activate this wireless function on all devices that will participate in the process. It is possible to connect both two devices according to the "point-to-point" scheme, and up to eight devices according to the "point-to-multipoint" scheme. One device will become the master, and the remaining seven or less will become slaves. It is better to activate the Bluetooth in the main device first, which everyone else will look for.

Problems with Bluetooth manifest themselves in different ways: the adapter does not connect, the Piconet does not work, the phone does not broadcast an audio stream, the receiver does not hear the audio signal, the batch file transfer function does not work, settings management is not available, the connected device cannot be connected, the connection speed is below 1 Mbps /s, Internet access point not working, Bluetooth 5.3 specification device that supports all protocols and profiles keeps disconnecting, icon missing from taskbar or desktop. As a rule, in order for a wireless connection to work, it is enough to fix just one problem.
