Bluetooth is a short-range radio link intended to replace the cable(s)
connecting portable and/or fixed electronic devices. Bluetooth operates
in the unlicensed ISM band at 2.4 GHz. The Bluetooth protocol uses a
combination of circuit and packet switching. Bluetooth can support an
asynchronous data channel, up to three simultaneous synchronous voice
channels, or a channel which simultaneously supports asynchronous data
and synchronous voice.
Each voice channel supports a 64 kb/s synchronous
(voice) channel in each direction.
The asynchronous channel can support
maximal 723.2 kb/s asymmetric (and still up to 57.6 kb/s in the return
channels, or a channel which simultaneously supports asynchronous data
and synchronous voice. Each voice channel supports a 64 kb/s synchronous
(voice) channel in each direction. The asynchronous channel can support
maximal 723.2 kb/s asymmetric (and still up to 57.6 kb/s in the return
direction), or 433.9 kb/s symmetric.
.Pp
The Bluetooth system provides a point-to-point connection (only two
Bluetooth units involved), or a point-to-multipoint connection.
In the point-to-multipoint connection,
the channel is shared among several Bluetooth units.
Two or more units sharing the same channel form a
.Dq piconet .
One Bluetooth unit acts as the master of the piconet, whereas the other
unit(s) acts as slave(s).
Up to seven slaves can be active in the piconet.
The Bluetooth system provides a point-to-point connection (only two
Bluetooth units involved), or a point-to-multipoint connection. In the
point-to-multipoint connection, the channel is shared among several
Bluetooth units. Two or more units sharing the same channel form a
.Em piconet .
One Bluetooth unit acts as the master of the piconet, whereas the other
unit(s) acts as slave(s). Up to seven slaves can be active in the piconet.
In addition, many more slaves can remain locked to the master in a so-called
parked state.
These parked slaves cannot be active on the channel, but remain
synchronized to the master.
Both for active and parked slaves, the channel
parked state. These parked slaves cannot be active on the channel, but remain
synchronized to the master. Both for active and parked slaves, the channel
access is controlled by the master.
.Pp
Multiple piconets with overlapping coverage areas form a
.Dq scatternet .
Each piconet can only have a single master.
However, slaves can participate
in different piconets on a time-division multiplex basis.
In addition, a master in one piconet can be a slave in another piconet.
The piconets shall not be frequency-synchronized.
Each piconet has its own hopping channel.
.Ss Time Slots
The channel is divided into time slots, each 625 usec in length.
The time
slots are numbered according to the Bluetooth clock of the piconet master.
The slot numbering ranges from 0 to 2^27 -1 and is cyclic with a cycle length
of 2^27.
In the time slots, master and slave can transmit packets.
.Ss SCO Link
The SCO link is a symmetric, point-to-point link between the master and a
specific slave.
The SCO link reserves slots and can therefore be considered
as a circuit-switched connection between the master and the slave.
The SCO link typically supports time-bounded information like voice.
The master can
support up to three SCO links to the same slave or to different slaves.
A
slave can support up to three SCO links from the same master, or two SCO
links if the links originate from different masters.
SCO packets are never retransmitted.
.Ss ACL Link
In the slots not reserved for SCO links, the master can exchange packets
with any slave on a per-slot basis.
The ACL link provides a packet-switched
connection between the master and all active slaves participating in the
piconet.
Both asynchronous and isochronous services are supported.
Between a master and a slave only a single ACL link can exist.
For most ACL packets,

.Sh HOST CONTROLLER INTERFACE (HCI)
The HCI provides a command interface to the baseband controller and link
manager, and access to hardware status and control registers.

device and some remote device.
.Pp
CID assignment is relative to a particular device and a device can assign CIDs
independently from other devices.
Thus, even if the same CID value has been
independently from other devices. Thus, even if the same CID value has been
assigned to (remote) channel endpoints by several remote devices connected
to a single local device, the local device can still uniquely associate each
remote CID with a different device.

device nodes interface is mutually exclusive with Netgraph interface.
.El
.Sh DEVICE NODES INTERFACE
The
.Nm
driver can create or destroy endpoint device nodes on request. This
feature can be used to implement external firmware download utility.
.Pp
The control transfers can only happen on the control endpoint which
is always endpoint 0. Control request are issued by
.Xr ioctl 2
calls.
.Pp
Only incoming transfers are supported on an interrupt endpoint. To perform I/O
on an interrupt endpoint
.Xr read 2
should be used. All I/O operations on a interrupt endpoint are unbuffered.
.Pp
The bulk transfers can be in or out depending on the endpoint. To perform
I/O on a bulk endpoint
.Xr read 2
and
.Xr write 2
should be used. All I/O operations on a bulk endpoint are unbuffered.
.Pp
The control endpoint (endpoint 0) handles the following
.Xr ioctl 2
calls:
.Bl -tag -width foo
.It Dv USB_GET_DEVICE_DESC Pq Vt usb_device_descriptor_t

.Ed
.It Dv USB_DO_REQUEST Pq Vt "struct usb_ctl_request"
Send a USB request to the device on the control endpoint.
Any data sent to/from the device is located at
.Va data .
The size of the transferred data is determined from the
.Va request .
The
.Va addr
field is ignored in this call.
The
.Va flags
field can be used to flag that the request is allowed to
be shorter than the requested size, and the
.Va actlen
will contain the actual size on completion.
.Bd -literal
struct usb_ctl_request {
int addr;
usb_device_request_t request;
void *data;
int flags;
#define USBD_SHORT_XFER_OK 0x04 /* allow short reads */

};
.Ed
This is a dangerous operation in that it can perform arbitrary operations
on the device. Some of the most dangerous (e.g., changing the device
address) are not allowed.
.It Dv USB_GET_DEVICEINFO Pq Vt "struct usb_device_info"
Get an information summary for the device. This call will not issue any USB
transactions.
.El
.Sh SHUTDOWN
This node shuts down when the corresponding USB device is un-plugged.

.Xr read 2
should be used. All I/O operations on a interrupt endpoint are unbuffered.
Interrupt endpoint is always endpoint 1.
.Pp
Only outgoing bulk transfers are supported on a bulk endpoint. To perform
I/O on a bulk endpoint
.Xr write 2
should be used. All I/O operations on a bulk endpoint are unbuffered. Outgoing
bulk endpoint is always enpoint 2.

FIXME/TODO list
@ -12,30 +11,18 @@ This is a list of open issues for HCI node
it should be fine as long as Netgraph is SMP safe. Just need to
verify it.
3) HCI QoS handling
2) HCI QoS handling
Some code exists, but i have no idea how it should work. Will
understand and fix later. I only have CSR based hardware and
it does not support QoS.
4) Add proper handling for some HCI commands
3) Add proper handling for some HCI commands
HCI testing commands is one example. Also might implement Host to
Host Controller flow control (not sure if it is required).
5) Link security
Manage link keys and PINs. Options:
1) manage keys inside HCI node/unit itself
2) use user space daemon.
3) Mix option 1 and option 2.
6) Implement watchdog routine for HCI connections
Some code exists, but it is not used
7) Code cleanup
4) Code cleanup
Verify return codes from functions
Remove some waringns/errors

.Sh NAME
.Nm rfcomm_sppd
.Nd RFCOMM Serial Port Profile daemon
.Sh SYNOPSIS
.Nm
.Op Fl a Ar BD_ADDR
.Op Fl b
.Op Fl c Ar channel
.Op Fl t Ar tty
.Op Fl h
.Sh DESCRIPTION
The
.Nm
is a Serial Port Profile daemon. It opens RFCOMM connection to the
specified server's BD_ADDR and channel. Once connection is established
.Nm
provides access to the server's remote serial port via
.Xr pty 4
interface.
.Pp
.Nm
opens both master and slave pseudo terminals. This is done to ensure that
RFCOMM connection stays open until
.Nm
is terminated. The data received from the master pseudo terminal are sent over
the RFCOMM connection. The data received from the RFCOMM connection are written
into master pseudo terminal. The application in its turn opens slave pseudo
terminal and operates on it just like it would operate over the standard serial
port.
.Pp
The options are as follows:
.Bl -tag -width indent
.It Fl a Ar BD_ADDR
This requied option specifies the remote BD_ADDR of the RFCOMM server.
.It Fl b
Detach from the controlling terminal, i.e. run in background.
.It Fl c Ar channel
This required option specifies RFCOMM channel to connect to. This channel
must provide Serial Port service.
.It Fl t Ar tty
Slave pseudo tty name.
.It Fl h
Display usage message and exit.
.El
.Sh EXAMPLES
.Bl -tag -width indent
.It rfcomm_sppd -a 00:01:02:03:04:05 -c 1 -t /dev/ttyp1
.Pp
Will start
.Nm
and open RFCOMM connection to the server at
.Em 00:01:02:03:04:05
and channel
.Em 1 .
Once connection has been established
.Pa /dev/ttyp1
can be used to talk to the remote serial port on the server.
.El
.Sh FILES
.Bl -tag -width /dev/tty[p-sP-S][0-9a-v]x -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 DIAGNOSTICS
.Ex -std
.Sh BUGS
.Nm
currently is not integrated with SDP (Service Discovery Protocol).
