Sh NAME
Nm rfcomm_sppd
Nd RFCOMM Serial Port Profile daemon
Sh SYNOPSIS
Nm
Op Fl d Ar device
Op Fl m Ar mode
Op Fl p Ar psm
Op Fl s Ar service
Op Fl t Ar tty
Brq Fl a Ar address | Op Fl c Ar channel
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, or the first unused channel if none
was given.
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
In 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 specified 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 -width encrypt -offset xx
It auth
require devices be paired.
It encrypt
auth, plus enable encryption.
It secure
encryption, plus change of link key.
El
It Fl p Ar psm
Specify the
Qq Protocol/Service Multiplexer
value to be used for the RFCOMM protocol.
In client mode where Service Discovery is being used, this value
will be ignored.
It Fl s Ar service
Name of service class to connect to or register.
If no
Ar service
is given, the default
Qq Serial Port
service class will be used.
Known service classes are:
Pp
Bl -tag -compact -width DUN -offset xx
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.
El
Sh FILES
Bl -tag -width ".Pa /dev/tty[p-sP-S][0-9a-v]" -compact
It Pa /dev/pty[p-sP-S][0-9a-v]
master pseudo terminals
It Pa /dev/tty[p-sP-S][0-9a-v]
slave pseudo terminals
El
Sh EXIT STATUS
Ex -std
Sh EXAMPLES
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
Pp
in your
Xr pppd 8
configuration file.
