SPP (Serial Port Profile)

The Serial Port Profile (SPP) is a Bluetooth feature that enables wireless devices to communicate as if connected by a serial cable. It allows devices like tablets, smartphones, and computers to exchange data—similar to a traditional serial connection—without physical wires. SPP is commonly used for applications such as transferring files, controlling hardware, or connecting peripherals like barcode scanners and GPS devices. It simplifies and streamlines communication, providing a reliable, portable way for compatible devices to share information seamlessly over Bluetooth.
