BTHIDEV(4)              NetBSD Kernel Interfaces Manual             BTHIDEV(4)


NAME

     bthidev -- Bluetooth Human Interface Device support


SYNOPSIS

     bthidev* at bthub?

     btkbd*   at bthidev? reportid ?
     btms*    at bthidev? reportid ?


DESCRIPTION

     The bthidev driver handles all Bluetooth Human Interface Devices.  Each
     HID device can have several components, e.g., a keyboard and a mouse.
     These components use different report identifiers to distinguish which
     component data is coming from.  The bthidev driver may have several chil-
     dren attached that handle particular components and dispatches data to
     them based on the report id.

     Normally, Bluetooth HIDs will be attached using the btdevctl(8) program.
     The following properties are used by the bthidev driver during autocon-
     figuration:

     local-bdaddr     Local device address.

     remote-bdaddr    Remote device address.

     service-name     The bthidev driver matches the `HID' service.

     control-psm      This, if set, will indicate the PSM to use for the Con-
                      trol channel.  If not set, L2CAP_PSM_HID_CNTL will be
                      used.

     interrupt-psm    This, if set, will indicate the PSM to use for the
                      Interrupt channel.  If not set, L2CAP_PSM_HID_INTR will
                      be used.

     descriptor       This required binary blob is the HID descriptor contain-
                      ing information about reports the device will produce,
                      and obtained via SDP.

     reconnect        If this boolean value is set, and is true, then the
                      bthidev driver will initiate reconnections to the remote
                      device when no connection is present.

     link-mode        This optional string represents the link mode of the
                      baseband link, and may be one of `auth', `encrypt', or
                      `secure'.

     When the bthidev driver has configured its children, it will initiate a
     connection to the remote device.  If this fails and the reconnect flag is
     not set, it will then wait for the device to initiate the connection.

HISTORY

     The bthidev driver was written by Iain Hibbert under the sponsorship of
     Itronix, Inc. and first appeared in NetBSD 4.0.
