hciattach: attach serial devices via UART HCI to BlueZ stack
hciattach - attach serial devices via UART HCI to BlueZ stack
hciattach [OPTIONS] <tty> <type|id> [speed] [flow] [sleep] [bdaddr]
hciattach(1) is used to attach a serial UART to the Bluetooth stack as HCI transport interface.
- Send break
- Don't detach from controlling terminal.
- 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.
- List all available configurations.
- Set the HCI device into raw mode. The kernel and bluetooth daemon will ignore it.
- -h, --help
- Show help options
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
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 ID (manufacturer id, product id)
Description 0x0105, 0x080a Xircom PCMCIA cards: Credit Card Adapter and Real Port Adapter 0x0160, 0x0002 BrainBoxes PCMCIA card (BL620)
The speed specifies the UART speed to use. Baudrates higher than 115200bps
require vendor specific initializations that are not implemented for all
types of devices. In general the following speeds are supported:
Supported vendor devices are automatically initialised to their respective best settings.
9600 19200 38400 57600 115200 230400 460800 921600
- If the 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.
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.
- 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.
