HCIATTACH(8) Linux System Administration HCIATTACH(8)NAME
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.
OPTIONS -b Send break.
-n Don't detach from controlling terminal.
-p Print the PID when detaching.
Specify an initialization timeout. (Default is 5 seconds.)
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
any Unspecified HCI_UART interface, no vendor specific options
Ericsson based modules
digi Digianswer based cards

csr CSR Casira serial adapter or BrainBoxes serial dongle (BL642)
bboxes BrainBoxes PCMCIA card (BL620)
swave Silicon Wave kits

ath3k Atheros AR300x based serial Bluetooth device
Supported IDs are (manufacturer id, product id)

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.

HCITOOL(1) Linux System Administration HCITOOL(1)NAME
hcitool - configure Bluetooth connections
hcitool [-i <hciX>] [command [command parameters]]
hcitool is used to configure Bluetooth connections and send some special command to Bluetooth devices. If no command is given, or if the
option -h is used, hcitool prints some usage information and exits.
OPTIONS -h Gives a list of possible commands
The command is applied to device hciX , which must be the name of an installed Bluetooth device. If not specified, the command will
be sent to the first available Bluetooth device.
dev Display local devices
inq Inquire remote devices. For each discovered device, Bluetooth device address, clock offset and class are printed.
scan Inquire remote devices. For each discovered device, device name are printed.
Print device name of remote device with Bluetooth address bdaddr.
Print device name, version and supported features of remote device with Bluetooth address bdaddr.
spinq Start periodic inquiry process. No inquiry results are printed.
epinq Exit periodic inquiry process.
cmd <ogf> <ocf> [parameters]
Submit an arbitrary HCI command to local device. ogf, ocf and parameters are hexadecimal bytes.
con Display active baseband connections
cc [--role=m|s] [--pkt-type=<ptype>] <bdaddr>
Create baseband connection to remote device with Bluetooth address bdaddr. Option --pkt-type specifies a list of allowed packet
types. <ptype> is a comma-separated list of packet types, where the possible packet types are DM1, DM3, DM5, DH1, DH3, DH5, HV1,
HV2, HV3. Default is to allow all packet types. Option --role can have value m (do not allow role switch, stay master) or s (allow
role switch, become slave if the peer asks to become master). Default is m.
dc <bdaddr> [reason]
Delete baseband connection from remote device with Bluetooth address bdaddr. The reason can be one of the Bluetooth HCI error
codes. Default is 19 for user ended connections. The value must be given in decimal.
sr <bdaddr> <role>
Switch role for the baseband connection from the remote device to master or slave.
cpt <bdaddr> <packet types>
Change packet types for baseband connection to device with Bluetooth address bdaddr. packet types is a comma-separated list of
packet types, where the possible packet types are DM1, DM3, DM5, DH1, DH3, DH5, HV1, HV2, HV3.
Display received signal strength information for the connection to the device with Bluetooth address bdaddr.
Display link quality for the connection to the device with Bluetooth address bdaddr.
tpl <bdaddr> [type]
Display transmit power level for the connection to the device with Bluetooth address bdaddr. The type can be 0 for the current
transmit power level (which is default) or 1 for the maximum transmit power level.
Display AFH channel map for the connection to the device with Bluetooth address bdaddr.
lp <bdaddr> [value]
With no value, displays link policy settings for the connection to the device with Bluetooth address bdaddr. If value is given,
sets the link policy settings for that connection to value. Possible values are RSWITCH, HOLD, SNIFF and PARK.
lst <bdaddr> [value]
With no value, displays link supervision timeout for the connection to the device with Bluetooth address bdaddr. If value is given,
sets the link supervision timeout for that connection to value slots, or to infinite if value is 0.
Request authentication for the device with Bluetooth address bdaddr.
enc <bdaddr> [encrypt enable]
Enable or disable the encryption for the device with Bluetooth address bdaddr.
Change the connection link key for the device with Bluetooth address bdaddr.
Read the clock offset for the device with Bluetooth address bdaddr.
clock [bdaddr] [which clock]
Read the clock for the device with Bluetooth address bdaddr. The clock can be 0 for the local clock or 1 for the piconet clock
(which is default).
