Nowadays, everyone knows what Bluetooth is. Moreover, almost everyone knows how to use it. But few have gone deep into this topic and tried to understand how wireless communication works. In this article we will analyze what a Bluetooth address is in Android devices, why you need it and where to find it.
What is the address of a network adapter
It should be noted right away that Bluetooth is the same network adapter as a Wi-Fi module or network card. The principle of building communication in all these technologies is similar, the differences are only in communication standards, data transmission speed and coverage radius (applies only to wireless adapters).
So, like any other network module, Bluetooth also has its own local MAC-address, for example, C5: 87: BR: 7W: H3: 40.
This is the local address Bluetooth in Android – gadgets. Of course, you should understand that each device is assigned unique values. That is, you cannot find two devices with the same address. This is necessary so that gadgets can detect and identify each other. In addition, when transferring information, an identifier is needed that will identify the recipient.
For example, when you send a letter, you indicate the address of the recipient's residence (or in the case of email, you indicate the email address). The same principle works with Bluetooth communication. That is, the device is determined by the MAC-address Bluetooth, which makes it possible to pair.
Typically, users do not even need to know this data, since gadgets in the vast majority of cases automatically determine all the necessary information. When pairing devices, you see only the name of this or that phone (tablet or laptop), but the same MAC-addresses are hidden under the name.
In other words, for example, when pairing to transfer files, gadgets interact precisely by their unique MAC-address. As already mentioned, the user does not need to know them, but sometimes it is just necessary. So we come to the question of how to find out Bluetooth the address in Android

Network module information
It is quite easy to find all the necessary information about certain modules in your phone or tablet on Android. In this case, you do not have to search and install any additional applications. Enter the menu of your smartphone (or tablet). Find the 'Settings' shortcut, as a rule, it is made in the form of a gear.
Open the settings. Further, on older versions Android, you should turn the page to the very bottom. At the very end, you will see the item 'About device'.
On newer versions Android you need to go to the 'Options' tab and drop the menu to the very bottom. There will also be an item called 'About device'.
We open it. Next, go to the 'Status' category. It remains only to find the string 'Bluetooth'. Under it, you will see the MAC-address.
It is worth remembering that Bluetooth must be enabled. Otherwise, the specified line will display the inscription 'Not available'.
As you can see, everything is very easy and simple. But, how to find out the MAC of not your own, for example, a smartphone, but the device to which you need to connect? There is nothing difficult here either, but you need to prepare in advance.
We connect to the Internet, open the Play Market and write the name of the application in the search bar – Bluetooth Address Finder. Select the application of the same name from the results and install it. Next, open the program and click the 'Begin searching procedure' button. Below there will be a list of MAC-addresses of all devices currently available to you, on which Bluetooth is enabled.
