What is a MAC address?
A MAC (Media Access Control) address is a unique identifier assigned to network interfaces for communications at the data link layer of a network segment. It is used to enable devices to identify each other on a local network. Each MAC address is composed of six pairs of hexadecimal digits, often separated by colons or hyphens. This uniqueness makes it an essential component of various network protocols and technologies, including Bluetooth.
In Bluetooth communication, MAC addresses help devices establish a connection by recognizing one another on the network. Each Bluetooth device has its own MAC address, which allows it to interact distinctly with others. Understanding how to find a Bluetooth device’s MAC address can be crucial for troubleshooting connectivity issues or setting up new connections.
