the Linux (BlueZ) API.
- L2CAP or RFCOMM connections can require the baseband radio link
mode be any of:
authenticated (devices are paired)
encrypted (implies authentication)
secured (encryption, plus generate new link key)
- for sockets, the mode is set using setsockopt(2) and the socket
connection will be aborted if the mode change fails.
- mode settings will be applied during connection establishment, and
for safety, we enter a wait state and will only proceed when the mode
settings are successfuly set.
- It is possible to change the mode on already open connections, but
not possible to guarantee that data already queued (from either end)
will not be delivered. (this is a feature, not a bug)
- bthidev(4) and rfcomm_sppd(1) support "auth", "encrypt" and
"secure" options
- btdevctl(8) by default enables "auth" for HIDs, and "encrypt" for
keyboards (which are required to support it)

|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility is a Serial Port Profile daemon, providing serial access over
|
|
an RFCOMM connection to a remote device.
|
|
.Nm
|
|
can work in client or server mode.
|
|
.Pp
|
|
In client mode,
|
|
.Nm
|
|
initiates an RFCOMM connection to the
|
|
.Ar service
|
|
at the remote
|
|
.Ar address .
|
|
.Pp
|
|
In server mode,
|
|
.Nm
|
|
registers the
|
|
.Ar service
|
|
with the local SDP server and listens on the specified RFCOMM
|
|
.Ar channel
|
|
for an incoming connection.
|
|
.Pp
|
|
The options are as follows:
|
|
.Bl -tag -width ".Fl c Ar channel"
|
|
.It Fl a Ar address
|
|
Client mode.
|
|
Specify the address of the remote RFCOMM device.
|
|
The address can be specified as BD_ADDR or name.
|
|
If given as a name, then the
|
|
.Nm
|
|
utility will attempt to resolve the name via
|
|
.Xr bt_gethostbyname 3 .
|
|
.It Fl c Ar channel
|
|
Server mode.
|
|
Specify the RFCOMM channel number to listen on.
|
|
.Nm
|
|
will register the service with the local
|
|
.Xr sdpd 8
|
|
daemon.
|
|
Note that registering services with
|
|
.Xr sdpd 8
|
|
is a privileged operation.
|
|
.It Fl d Ar device
|
|
Use the local device with the specifed address.
|
|
The device can be specified by BD_ADDR or device name.
|
|
See
|
|
.Xr btconfig 8
|
|
for a list of available devices.
|
|
If no
|
|
.Ar device
|
|
is specified, the connection will be set up on a system determined device.
|
|
.It Fl m Ar mode
|
|
Set connection link mode.
|
|
Supported modes are:
|
|
.Pp
|
|
.Bl -tag -compact -offset indent
|
|
.It auth
|
|
require devices be paired.
|
|
.It encrypt
|
|
auth, plus enable encryption.
|
|
.It secure
|
|
encryption, plus change of link key.
|
|
.El
|
|
.It Fl s Ar service
|
|
This is the service class that will be searched for on the remote device.
|
|
If no
|
|
.Ar service
|
|
is given, the default
|
|
.Qq Serial Port
|
|
service class will be used.
|
|
Known service classes are:
|
|
.Pp
|
|
.Bl -tag -compact -offset indent
|
|
.It DUN
|
|
Dialup Networking
|
|
.It LAN
|
|
LAN access using PPP
|
|
.It SP
|
|
Serial Port
|
|
.El
|
|
.Pp
|
|
In client mode, the service class may be given as a channel number, for instances
|
|
where the remote device does not provide Service Discovery.
|
|
.It Fl t Ar tty
|
|
Slave pseudo tty name.
|
|
If this option is given,
|
|
.Nm
|
|
will detach from the controlling process after the bluetooth connection is
|
|
made, and operate over the named
|
|
.Xr pty 4
|
|
pair.
|
|
Otherwise, stdin/stdout will be used.

|
|
.Dl rfcomm_sppd -a 00:01:02:03:04:05 -s 1 -t /dev/ttyp1

.Pp
|
|
Will open an RFCOMM connection to the server at
|
|
.Li 00:01:02:03:04:05
|
|
on channel
|
|
.Li 1 .
|
|
Once the connection has been established,
|
|
.Nm
|
|
will detach and
|
|
.Pa /dev/ttyp1
|
|
can be used to communicate with the remote serial port on the
|
|
server, e.g. with the use of
|
|
.Pp
|
|
.Dl cu -l /dev/ttyp1
|
|
.Pp
|
|
In order to use
|
|
.Nm
|
|
to automatically create a secured link for
|
|
.Xr pppd 8 ,
|
|
use
|
|
.Dl pty Qo rfcomm_sppd -a 00:01:02:03:04:05 -s DUN -m secure Qc
|
