       hciattach - attach serial devices via UART HCI to BlueZ stack


       hciattach  [-b] [-n] [-p] [-t timeout] [-s speed] [-l] [-r] tty type|id
       speed flow bdaddr


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


       -b     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 bluetoothd will
              ignore it).

       tty    This specifies the serial device to attach. A leading  /dev  can
              be omitted. Examples: /dev/ttyS1 ttyS2

              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 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.
