RFCOMM – Radio Frequency Communications Protocol
The Bluetoothª system uses the Radio Frequency Communications Protocol to emulate serial ports over the L2CAP (Logical Link Controller and Adaptation Protocol). The protocol is based on the ETSI standard TS 07.10, however only a subset of this standard is used within Bluetoothª. The RFCOMM protocol is capable of supporting up to 60 simultaneous connections between two Bluetoothª devices. The number of connections that can be used simultaneously in a Bluetooth device is implementation-specific.
