hciattach - Man Page

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 daemon 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 supported 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.

9600
19200
38400
57600
115200
230400
460800
921600
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 hardware memory. Instead it must be uploaded during the initialization process. If this argument is specified, then the address will be used to initialize the device. Otherwise, a default address will be used.
