rfcomm - RFCOMM configuration utility
rfcomm [OPTIONS] <COMMAND>
<dev>
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.
- -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
- 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.
