hciattach - attach serial devices via UART HCI to BlueZ stack

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
- 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
- description
- any
- Unspecified HCI_UART interface, no vendor specific options
- ericsson
- Ericsson based modules
- digi
- Digianswer based cards
- xircom
- Xircom PCMCIA cards: Credit Card Adapter and Real Port Adapter
- csr
- CSR Casira serial adapter or BrainBoxes serial dongle (BL642)
- bboxes
- BrainBoxes PCMCIA card (BL620)
- swave
- Silicon Wave kits
- bcsp
- Serial adapters using CSR chips with BCSP serial protocol
- ath3k
- Atheros AR300x based serial Bluetooth device
- intel
- Intel Bluetooth device
Supported IDs are (manufacturer id, product id)
- 0x0105, 0x080a
- Xircom PCMCIA cards: Credit Card Adapter and Real Port Adapter
- 0x0160, 0x0002
- BrainBoxes PCMCIA card (BL620)
- 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.
- sleep
- 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.
