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
     copyright 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.
