NAMEhciattach − attach serial devices via UART HCI to BlueZ stack

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

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

OPTIONS−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.
