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.
