SYNOPSIS
bthidev* at bthub?
btkbd* at bthidev? reportid ?
btms* at bthidev? reportid ?
DESCRIPTION
Thebthidev
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 children 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 autoconfiguration:
- 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 Control 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 containing 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.
