description
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
-i
<hciX>
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.
commands
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.
name <bdaddr>
Print device name of remote device with Bluetooth address
bdaddr.
info <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.
rssi <bdaddr>
Display received signal strength information for the connection
to the device with Bluetooth address bdaddr.
lq <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.
afh <bdaddr>
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.
auth <bdaddr>
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.
key <bdaddr>
Change the connection link key for the device with Bluetooth
address bdaddr.
clkoff <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).
