Covert Bluetooth communications refers to the use of Bluetooth technology to transmit information in a way that is hidden or discreet, often to avoid detection. This kind of communication is commonly used for covert operations, surveillance, espionage, or situations where secretive communication is necessary. Bluetooth is a wireless technology that allows devices to communicate with each other over short distances, usually up to 100 meters (depending on the Bluetooth class). When used covertly, Bluetooth allows for communication without the need for wires or obvious signals, making it a popular choice for discreet and sometimes clandestine interactions.
