NAME
       hciattach - attach serial devices via UART HCI to BlueZ stack

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

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

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

       speed  The speed specifies the UART speed to use. Baudrates higher than 115.200bps require  vendor  specific  initializa-
              tions 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.
