NAME
ng_bt3c — Netgraph node type that is also a 3Com Bluetooth PC card driver
SYNOPSIS
#include <sys/types.h>
#include <netgraph/bluetooth/include/ng_bt3c.h>
DESCRIPTION
The btccc node type is both a persistent Netgraph node type and a driver
for the 3Com Bluetooth PC card (3CRWB6096-HP). It implements a Bluetooth
HCI UART transport layer as per chapter H4 of the Bluetooth Specification
Book v1.1. A new node is created when the card is plugged.
In order to use the card one MUST download the firmware first. Due to
copyright issues the firmware cannot be provided with this driver. The
firmware can be obtained from the Windows driver package that can be
downloaded from the 3Com web site at no charge. The firmware name is
BT3CPCC.BIN. To load the firmware into the card, use bt3cfw(8). I am
using the original firmware that came with the card on CD-ROM.
MD5 (BT3CPCC.BIN) = 36170fda56ea9fdbf1702c966f8a97f1
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. HCI frames received on hook are
transmitted out. No modification to the data is performed in either
direction.
HARDWARE
The ng_bt3c driver provides support for the 3Com/HP 3CRWB6096-A PCCARD
bluetooth adapter.
HOOKS
This node type supports the following hooks:
hook single HCI frame contained in single mbuf structure.
CONTROL MESSAGES
This node type supports the generic control messages, plus the following:
NGM_BT3C_NODE_GET_STATE (get_state)
Returns the current receiving state for the node.
NGM_BT3C_NODE_SET_DEBUG (set_debug)
This command takes an integer argument and sets the current debug
level for the node.
NGM_BT3C_NODE_GET_DEBUG (get_debug)
Returns an integer containing the current debug level for the node.
NGM_BT3C_NODE_GET_QLEN (get_qlen)
This command takes a parameter that specifies queue number and
returns the current length of the queue for the node.
NGM_BT3C_NODE_SET_QLEN (set_qlen)
This command takes two parameters that specify the queue number and
the maximum length of the queue and sets the maximum length of the
queue for the node.
NGM_BT3C_NODE_GET_STAT (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_BT3C_NODE_RESET_STAT (reset_stat)
Reset all statistic counters to zero.
NGM_BT3C_NODE_DOWNLOAD_FIRMWARE
Download card firmware.
SHUTDOWN
This node shuts down when the corresponding card is un-plugged.

BUGS
The driver is based on information obtained from Jose Orlando Pereira
<jop@di.uminho.pt> and disassembled the W2K driver.
