What is Bluetooth, and how does it work?
Bluetooth is a wireless technology that allows devices to communicate over short distances using radio waves. It operates in the 2.4 GHz ISM band and uses low power to transmit data between devices, such as smartphones, tablets, headphones, and other peripherals. This technology enables a seamless connection without the need for cables or direct line-of-sight.
Devices must go through a pairing process to communicate via Bluetooth. This involves one device sending a connection request to another, which, once accepted, allows the devices to exchange data within a specified range, typically around 30 feet. However, this convenience can lead to unwanted connections if not properly managed.
Why am I experiencing unwanted Bluetooth connections?
Unwanted Bluetooth connections can occur for several reasons. Most commonly, this happens when your device’s Bluetooth settings are configured to allow visibility to all nearby devices. This visibility invites requests from unknown devices seeking to connect, resulting in unsolicited connections.
