NAME
rfcomm - RFCOMM configuration utility
SYNOPSIS
rfcomm [OPTIONS] <COMMAND> <dev>
DESCRIPTION
rfcomm(1) is used to set up, maintain, and inspect the RFCOMM configu-
ration 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 termi-
nated 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.
