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.
