ng_ubt -- Netgraph node type that is also a driver for Bluetooth USB devices SYNOPSIS
#include <sys/types.h> #include <netgraph/bluetooth/include/ng_ubt.h> DESCRIPTION
The 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. The node has a single hook called 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 hook are transmitted out. The node will drop the HCI frame indicator unless the device requires it to be present. HARDWARE
The ng_ubt driver supports all Bluetooth USB devices that conform with the Bluetooth specification v1.1, including: o 3Com 3CREB96 o AIPTEK BR0R02 o EPoX BT-DG02 o Mitsumi Bluetooth USB adapter o MSI MS-6967 o TDK Bluetooth USB adapter HOOKS
This node type supports the following hooks: hook single HCI frame contained in a single mbuf structure. CONTROL MESSAGES
This node type supports the generic control messages, plus the following: NGM_UBT_NODE_GET_DEBUG Returns an integer containing the current debug level for the node. NGM_UBT_NODE_SET_DEBUG This command takes an integer argument and sets the current debug level for the node. 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. 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. 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. NGM_UBT_NODE_RESET_STAT Reset all statistic counters to zero. SHUTDOWN
This node shuts down when the corresponding USB device is un-plugged. SEE ALSO
netgraph(4), ugen(4), usb(4), ngctl(8) HISTORY
The ubt node type was implemented in FreeBSD 5.0. AUTHORS
Maksim Yevmenkin <m_evmenkin@yahoo.com> 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). BSD
