RFCOMM

RFCOMM is a protocol used in wireless communication to enable devices, like phones and Bluetooth accessories, to exchange data as if they were serial (RS-232) ports. It creates a virtual communication channel over Bluetooth, allowing applications to send and receive data reliably. Think of it as a digital "cable" that links devices wirelessly, making data transfer simple and standardized for applications like wireless headsets, printers, or other peripherals. RFCOMM handles the connection setup, data transfer, and error checking, ensuring smooth and consistent communication between Bluetooth-enabled devices.
