NAME

     bt3c -- 3Com Bluetooth PC Card driver

SYNOPSIS

     bt3c* at pcmcia? function ?

DESCRIPTION

     The bt3c driver provides support for the 3Com Bluetooth PC Card, model 3CRWB6096, to the Bluetooth protocol stack.

FIRMWARE

     This card needs firmware loaded before it will work. Due to copyright restrictions we cannot distribute the firmware with NetBSD, but if you
     have the card then you should have received a CD with the drivers on, or you may download the latest version from the 3Com website. Create a
     directory named bt3c in the search path of the firmload(9) kernel subsystem. Now, extract the driver archive and find the firmware file
     called BT3CPCC.bin, and place this file in the newly created directory. The firmware will be loaded automatically as needed.

DIAGNOSTICS

     bt3c%d: Cannot open firmware
	  This will be printed to the console if the device cannot open the firmware file as described above.

     bt3c%d: Antenna In
     bt3c%d: Antenna Out
	  If the kernel is compiled with the DIAGNOSTIC option, these messages will be produced on the console when the card antenna position is
	  changed.

     bt3c%d: sleeping
     bt3c%d: waking up
	  These messages will be produced when the card is enabled or disabled due to power change events.

HISTORY

     This bt3c device driver was written by Iain Hibbert using FreeBSD and BlueZ drivers as a reference.  It first appeared in NetBSD 4.0.

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
             Returns the current receiving state for the node.

     NGM_BT3C_NODE_GET_DEBUG
             Returns an integer containing the current debug level for the node.

     NGM_BT3C_NODE_SET_DEBUG
             This command takes an integer argument and sets the current debug level for the node.

     NGM_BT3C_NODE_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
             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
             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 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.
