NAME

       rfcomm - RFCOMM configuration utility

SYNOPSIS

       rfcomm [ options ] < command > < dev >

DESCRIPTION

       rfcomm  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 authentification

       -E     Enable encryption

       -S     Secure connection

       -M     Become the master 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.
