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

TagDescription
-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").
-f [file]
  Specify alternate config file.
-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.

COMMANDS

TagDescription
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. If also the Bluetooth address is left out, it tries to read the data from the config file. This command can be terminated with the key sequence CTRL-C.
listen <dev> [channel]
  Listen on a specified RFCOMM channel for incoming connections. If no channel is specified, it will use the channel number 1. This command can be terminated with the key sequence CTRL-C.
bind <dev> [bdaddr] [channel]
  This binds the RFCOMM device to a remote Bluetooth device. The command did 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. If the Bluetooth address is also left out, it tries to read the data from the config file.

If all is specified for the RFCOMM device, then all devices that have bind yes set in the config will be bound.

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

If all is specified for the RFCOMM device, then all bindings will be removed. This command didn’t care about the settings in the config file.
