1. NAME

hciattach - attach serial devices via UART HCI to BlueZ stack

2. SYNOPSIS

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

3. DESCRIPTION

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

4. OPTIONS

-n

    Don't detach from controlling terminal.

-p

    Print the PID when detaching.

  • -t timeout
        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.

  • 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.
