NAME

6       rfcomm - RFCOMM configuration utility
7

SYNOPSIS

9       rfcomm [OPTIONS] <COMMAND> <dev>
10

DESCRIPTION

12       rfcomm(1)  is used to set up, maintain, and inspect the RFCOMM configu‐
13       ration of the Bluetooth subsystem in the Linux kernel. If no command is
14       given, or if the option -a is used, rfcomm prints information about the
15       configured RFCOMM devices.
16

OPTIONS

18       -h     Gives a list of possible commands.
19
20       -a     Prints information about all configured RFCOMM devices.
21
22       -r     Switch TTY into raw mode (doesn't work with "bind").
23
24       -i <hciX> | <bdaddr>
25              The command is applied to device hciX, which must be the name or
26              the  address of an installed Bluetooth device. If not specified,
27              the command will be use the first available Bluetooth device.
28
29       -A     Enable authentication
30
31       -E     Enable encryption
32
33       -S     Secure connection
34
35       -C     Become the central of a piconet
36
37       -L <seconds>
38              Set linger timeout
39

COMMANDS

41       show <dev>
42              Display the information about the specified device.
43
44       connect <dev> [bdaddr] [channel]
45              Connect the RFCOMM device to the remote Bluetooth device on  the
46              specified  channel.  If  no  channel  is  specified, it will use
47              the channel number 1. This command can be  terminated  with  the
48              key sequence CTRL-C.
49
50       listen <dev> [channel] [cmd]
51              Listen  on  a specified RFCOMM channel for incoming connections.
52              If no channel is specified, it will use the  channel  number  1,
53              but  a channel must be specified before cmd. If cmd is given, it
54              will be executed as soon as a  client  connects.  When the child
55              process  terminates  or  the client disconnect, the command will
56              terminate. Occurrences of {} in cmd will be replaced by the name
57              of the device used by the connection. This command can be termi‐
58              nated with the key sequence CTRL-C.
59
60       watch <dev> [channel] [cmd]
61              Watch is identical to listen except that when the child  process
62              terminates  or  the  client disconnect, the command will restart
63              listening with the same parameters.
64
65       bind <dev> [bdaddr] [channel]
66              This binds the RFCOMM device to a remote Bluetooth  device.  The
67              command  does  not establish a connection to the remote  device,
68              it only creates the binding. The connection will be  established
69              right  after  an application tries to open the RFCOMM device. If
70              no channel number is specified, it uses the channel number 1.
71
72       release <dev>
73              This command releases a defined RFCOMM binding.
74
75              If all is specified for the RFCOMM  device,  then  all  bindings
76              will be removed.
