NG_BT3C(4)	       FreeBSD Kernel Interfaces Manual		    NG_BT3C(4)

NAME
     BTCCC -- Netgraph node type that is also a	3Com Bluetooth PC card driver

SYNOPSIS
     #include <sys/types.h>
     #include <ng_bt3c.h>

DESCRIPTION
     The BTCCC node type is both a persistent Netgraph node type and a driver
     for 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	firmware first.	Due to copy-
     right issues I will no longer provide firmware with the 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 firmware info	the card use bt3cfw(8).	 I'm using
     original firmware that came with the card on CD-ROM.

	   MD5 (BT3CPCC.BIN) = 36170fda56ea9fdbf1702c966f8a97f1

     For OLDCARD systems the entry in pccard.conf(5) might look	like this

	   # 3Com 3CRWB60-A Bluetooth PC Card
	   card	"3COM" "3CRWB60-A" "Bluetooth PC Card"
		   config  auto	   "btccc" ?
		   insert  /usr/sbin/bt3cfw -n $device -f /etc/BT3CPCC.bin

     Do	not forget to load module and SIGHUP pccardd(8).

     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.

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 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 current debug	level
	  for the node.

     NGM_BT3C_NODE_GET_QLEN
	  This command takes a parameter that specifies	queue number and
	  returns current length of the	queue for the node.

     NGM_BT3C_NODE_SET_QLEN
	  This command takes two parameters that specify queue number and and
	  maximum length of the	queue and sets 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	obrained from Jose Orlando Pereira
     <jop@di.uminho.pt>	and disassembled W2K driver.
