NAME
hciattach - attach serial devices via UART HCI to BlueZ stack
SYNOPSIS
hciattach [OPTIONS] <tty> <type|id> [speed] [flow] [sleep] [bdaddr]
hciattach -1
DESCRIPTION
hciattach(1) is used to attach a serial UART to the Bluetooth stack as
HCI transport interface.
OPTIONS
-i Send break
-n Don't detach from controlling terminal.
-p Print the PID when detaching.
-t timeout
Specify an initialization timeout. Default is 5 seconds.
-s speed
Specify an initial speed instead of the hardware default.
-l List all available configurations.
-r Set the HCI device into raw mode. The kernel and bluetooth dae-
mon will ignore it.
-h, --help
Show help options
ARGUMENTS
show This specifies the serial device to attach. A leading /dev can
be omitted.
Examples: /dev/ttyS1 ttyS2
type|id
The type or id of the Bluetooth device that is to be attached,
i.e. vendor or other device specific identifier. Currently sup-
ported types are

speed The speed specifies the UART speed to use. Baudrates higher than
115200bps require vendor specific initializations that are not
implemented for all types of devices. In general the following
speeds are supported:
Supported vendor devices are automatically initialised to their
respective best settings.

flow If the flow is appended to the list of options then hardware
flow control is forced on the serial link (CRTSCTS). All above
mentioned device types have flow set by default. To force no
flow control use noflow instead.
sleep|nosleep
Enables hardware specific power management feature. If sleep is
appended to the list of options then this feature is enabled. To
disable this feature use nosleep instead. All above mentioned
device types have nosleep set by default.
Note: This option will only be valid for hardware which support
hardware specific power management enable option from host.
bdaddr The bdaddr specifies the Bluetooth Address to use. Some devices
(like the STLC2500) do not store the Bluetooth address in hard-
ware memory. Instead it must be uploaded during the initializa-
tion process. If this argument is specified, then the address
will be used to initialize the device. Otherwise, a default ad-
dress will be used.
