hciattach - attach serial devices via UART HCI to BlueZ stack

hciattach [ -n ] [ -p ] [ -t timeout ] < tty > < type | id > [ speed ] [ flow ]

Hciattach is used to attach a serial UART to the Bluetooth stack as HCI transport interface.

-n

Don't detach from controlling terminal.

-p

Print the PID when detaching.

-ttimeout

Specify an initialization timeout. (Default is 5 seconds.)

<tty>

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

type

<speed>

The speed specifies the UART speed to use. Baudrates higher than 115.200bps require vendor specific initializations that are not implemented for all types of devices. In general the following speeds are supported:

9600, 19200, 38400, 57600, 115200, 230400, 460800, 921600

Supported vendor devices are automatically initialised to their respective best settings.

<flow>

If the keyword 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.
