RF communication (RFCOMM)

The RF Communication Protocol (RFCOMM) is a Bluetooth protocol that emulates the serial connection of an RS-232 interface with its control and data signals via the air interface.

The RFCOMM protocol is one of the Bluetooth host protocols and is also known as the Cable Replacement Protocol. RFCOMM can multiplex connections in Bluetooth via the Logical Link Control and Adaptation Protocol (L2CAP) and serve a maximum of 60 RS-232 connections.

The RFCOMM layer, on which network protocols such as the IP protocol, routing prot ocols such as the Point-to-Point Protocol (PPP), and transport protocols such as the Transmission Control Protocol (TCP) or the User Datagram Protocol (UDP) are built, enables current and future applications to communicate wirelessly. In doing so, applications run over one or more vertical channels of the Bluetooth protocol stack.

RFCOMM is based on the ETSI standard TS 07.10 and Q.931 of the International Telecommunication Union (ITU).
