RFCOMM(1)							     RFCOMM(1)

NAME
       rfcomm - RFCOMM configuration utility

SYNOPSIS
       rfcomm [ options ] < command > < dev >

DESCRIPTION
       rfcomm  is  used to set up, maintain, and inspect the RFCOMM configura‐
       tion 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.
