NAME

       rfcomm - RFCOMM configuration utility

SYNOPSIS

       rfcomm [OPTIONS] <COMMAND> <dev>

DESCRIPTION

       rfcomm(1) is used to set up, maintain, and inspect the RFCOMM configuration of the Bluetooth subsystem in
       the  Linux  kernel.  If no command is given, or if the option -a is used, rfcomm prints information about
       the configured RFCOMM devices.

OPTIONS

       -h     Gives a list of possible commands.

       -a     Prints information about all configured RFCOMM devices.

       -r     Switch TTY into raw mode (doesn't work with "bind").

       -i <hciX> | <bdaddr>
              The command is applied to device hciX, which must be the name  or  the  address  of  an  installed
              Bluetooth device. If not specified, the command will be use the first available Bluetooth device.

       -A     Enable authentication

       -E     Enable encryption

       -S     Secure connection

       -C     Become the central of a piconet

       -L <seconds>
              Set linger timeout

COMMANDS

       show <dev>
              Display the information about the specified device.

       connect <dev> [bdaddr] [channel]
              Connect  the RFCOMM device to the remote Bluetooth device on the specified channel. If no  channel
              is  specified, it will use the channel number 1. This command  can  be  terminated  with  the  key
              sequence CTRL-C.

       listen <dev> [channel] [cmd]
              Listen   on   a specified RFCOMM channel for incoming connections.  If no channel is specified, it
              will use the channel number 1, but a channel must be specified before cmd. If  cmd  is  given,  it
              will  be executed as soon as a  client  connects.  When the child process terminates or the client
              disconnect, the command will terminate. Occurrences of {} in cmd will be replaced by the  name  of
              the device used by the connection. This command can be terminated with the key sequence CTRL-C.

       watch <dev> [channel] [cmd]
              Watch  is  identical  to  listen  except  that  when  the  child  process terminates or the client
              disconnect, the command will restart listening with the same parameters.

       bind <dev> [bdaddr] [channel]
              This binds the RFCOMM device to a remote Bluetooth  device.  The  command  does  not  establish  a
              connection  to the remote  device, it only creates the binding. The connection will be established
              right after an application tries to open the RFCOMM device. If no channel number is specified,  it
              uses the channel number 1.

       release <dev>
              This command releases a defined RFCOMM binding.

              If all is specified for the RFCOMM device, then all bindings will be removed.
