installed Bluetooth device. If not specified, the command will be sent to
the first available Bluetooth device.
- -h
- Gives a list of possible 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=c|p]
[--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 c (do not allow
role switch, stay central) or p (allow role switch, become
peripheral if the peer asks to become central). Default is c.
- 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
central or peripheral.
- cpt <bdaddr>
<ptypes>
- Change packet types for baseband connection to device with Bluetooth
address bdaddr. ptypes 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.
- 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 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>

bdaddr.
- clock [bdaddr]
[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).
