.Sh NAME
|
|
.Nm ng_ubt
|
|
.Nd Netgraph node type that is also a driver for Bluetooth USB devices
|
|
.Sh SYNOPSIS
|
|
.In sys/types.h
|
|
.In netgraph/bluetooth/include/ng_ubt.h
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm ubt
|
|
node type is both a persistent Netgraph node type and a driver for
|
|
Bluetooth USB devices.
|
|
It implements a Bluetooth USB transport layer
|
|
as per chapter H2 of the Bluetooth Specification Book v1.1.
|
|
A new node is created when a supported USB device is plugged in.
|
|
.Pp
|
|
The node has a single hook called
|
|
.Dv hook .
|
|
Incoming bytes received on the device are re-assembled into HCI frames
|
|
(according to the length).
|
|
Full HCI frames are sent out on the hook.
|
|
The node will add a HCI frame indicator if the device did not send it.
|
|
HCI frames received on
|
|
.Dv hook
|
|
are transmitted out.
|
|
The node will drop the HCI frame indicator unless the device
|
|
requires it to be present.
|
|
.Sh HARDWARE
|
|
The
|
|
.Nm
|
|
driver supports all Bluetooth USB devices that conform with
|
|
the Bluetooth specification v1.1, including:

.Sh HOOKS
|
|
This node type supports the following hooks:
|
|
.Bl -tag -width indent
|
|
.It Dv hook
|
|
single HCI frame contained in a single
|
|
.Vt mbuf
|
|
structure.
|
|
.El
|
|
.Sh CONTROL MESSAGES
|
|
This node type supports the generic control messages, plus the following:
|
|
.Bl -tag -width indent
|
|
.It Dv NGM_UBT_NODE_GET_DEBUG
|
|
Returns an integer containing the current debug level for the node.
|
|
.It Dv NGM_UBT_NODE_SET_DEBUG
|
|
This command takes an integer argument and sets the current debug level
|
|
for the node.
|
|
.It Dv NGM_UBT_NODE_GET_QLEN
|
|
This command takes a parameter that specifies the queue number and returns
|
|
the current maximal length of the queue for the node.
|
|
.It Dv NGM_UBT_NODE_SET_QLEN
|
|
This command takes two parameters that specify the queue number and the maximum
|
|
length of the queue and sets the maximal length of the queue for the node.
|
|
.It Dv NGM_UBT_NODE_GET_STAT
|
|
Returns various statistic information for the node, such as: number of
|
|
bytes (frames) sent, number of bytes (frames) received and number of
|
|
input (output) errors.
|
|
.It Dv NGM_UBT_NODE_RESET_STAT
|
|
Reset all statistic counters to zero.
|
|
.El
|
|
.Sh SHUTDOWN
|
|
This node shuts down when the corresponding USB device is un-plugged.

|
.Sh BUGS
|
|
Isochronous USB transfers are broken.
|
|
This means that the USB device will not be able to transfer SCO data (voice).
|
|
USB interrupt transfers are implemented as bulk-in transfers (not really a bug).
